Real-life 3D images are expected to find widespread application in fields ranging from movies and TV broadcasts to industrial and educational uses. In response to the rapidly growing needs for 3D image production, Panasonic now offers a revolutionary solution: AG-3DA1 the world's first* integrated twin-lens FULL HD 3D camera recorder. The AG-3DA1 features a camera section with two integrated lens systems that are configured to resemble the human eyes, and a recorder section that records left-channel and right-channel full-HD images using the high-quality PH mode of the file-based AVCHD format. With the same approximate weight and size of a 2D camera recorder, the AG-3DA1 is easy to handle. It's also quick to operate, as it doesn't require any adjustment of the left and right lens alignment such as vertical gap, size difference, rotation and luminance difference. The AG-3DA1 frees the user from the kind of complex, cumbersome procedures of a conventional rig-type 3D camera system. Data files recorded onto a memory card are readily processed using a nonlinear editing system. With its excellent mobility , flexibility and low cost operation, the AG-3DA1 opens the door to 3D image production.
* As an integrated twin-lens 3D camera recorder capable of recording full-HD video to its memory card. As of August 2010 (based on our investigations).

Schematic of the AG-3DA1:
The left-channel and right-channel optical sections, image sensors, signal processing circuits and recording section are precisely synchronized. The AG-3DA1 outputs left-eye and right-eye full-HD image signals as simultaneous HD-SDI video and also records to the SD/SDHC memory cards in the AVCHD format.

The high-precision HD twin-lens system allows easy acquisition of natural-looking 3D images.
The Integrated Structure Revolutionizes Mobility for Nimble Camera Work
Conventional rig-type 3D camera systems are large and heavy because they mount two existing cameras onto a robust frame. They also require a separate recording system and power supply unit, which makes the cable connection complex and restricts the location and the type of camera work. As a result, the scenes that can be acquired with a rig-type 3D camera system are limited. The compact body of the AG-3DA1 integrated twin-lens FULL HD 3D camera recorder weighs only 2.4 kg (5.3lb). It offers the same portability and mobility as a conventional 2D camera recorder for flexible image acquisition. The AG-3DA1 enhances camera work for all kinds of 3D image production.
The Twin-Lens System Sets You Free From Complex Camera Adjustments for 3D Images
To achieve natural-looking 3D images, you need to pay close attention to the following key points for left- and right-eye images: (1) Vertical deviation, (2) Angle deviation, (3) Difference in brightness and color, (4) Rotation error, (5) Correct adjustment of the parallax, (6) Appropriate image composition. With a conventional rig-type 3D camera system using two separate cameras, these adjustments have to be made precisely for each and every scene. The two integrated optical systems of the AG-3DA1 eliminate the need for manual adjustments of (1) through (4), because they're performed entirely inside the camera recorder.* The optical systems are assembled with high precision, and the lenses, image sensors and signal processing circuits for the left and right systems are accurately synchronized (see the diagram on the previous page). The AG-3DA1 lets you concentrate only on the parallax adjustment and image composition.
*Fine adjustments of the vertical position, focus and iris are also possible.
HD Twin-Lens with No Adjustment for Image Acquisition
The distance between the two lens axes is approximately the same as the distance between the human eyes, to provide easy-to-view, natural-looking 3D images. The HD twin-lens system is set with a distance of about 60 mm (2.3 inches) between the two lenses. The lens axes, viewing angle, rotation, and gradation are pre-adjusted before the components are precisely assembled. This eliminates the need for lens adjustment before shooting. Camera operations such as focusing, zooming and iris adjustment are also synchronized for the left and right lenses.
The new twin HD lenses were designed exclusively for FULL HD 3D image acquisition. They boast low chroma aberration and high resolution, and deliver superb color reproduction, detailed nuances and crisp 3D images even in dark scenes - with minimal flare and ghosting. A built-in 5.6x (approx.) optical zoom function, which extends from 47.1 mm (35 mm equivalent) wide angle to 264 mm (35 mm equivalent) telephoto, covers a wide viewing angle that is well matched to 3D content production.

Convergence Point Adjustment Function
The parallax angle between the two lenses is varied inside the optical unit. This moves the convergence point (the reference plane of the 3D image) in a fore-and-aft direction to control the leaping and depth effects of recorded objects, and acquires natural-looking 3D images. The convergence point can be adjusted easily by using the CONV (convergence) dial* while viewing the L/R-MIX image on the LCD monitor.
*The dial function is switchable between CONV (convergence) adjustment and IRIS (iris) adjustment.
Display Functions Assist 3D Image Acquisition
The LCD monitor and viewfinder of the AG-3DA1 both display a variety of information to assist 3D image shooting and ensure superb 3D effects.
•3D Guide: This displays numerical values for the distance range of the subject to achieve better 3D effects while viewing. Natural-looking 3D images can be captured by using the displayed information as a guide. This function offers two modes: Guide Display 1 mode assumes playback on screens that are 196 cm/ 77 inches or smaller, and Guide Display 2 mode is designed for a screen size of 508 cm/ 200 inches.
•Convergence Point: This displays the numerical value of the convergence point together with the 3D Guide to assist adjustments.
•L/R-MIX Monitor Image Selector: The image display on the LCD monitor and viewfinder can be selected from three modes: Left Lens (no mode indication), Right Lens (R-IMAGE) and Left/Right Mix (MIX).
*When the subject is located outside the distance range indicated by the 3D Guide, it may result in a double image or an unnatural image without proper 3D effects.
Dual 3MOS for High-Quality FULL HD 3D Images
The AG-3DA1 is equipped with two 1/4.1 type 2.07-megapixel (approx.) 3MOS units for left- and right-eye images. Full-pixel full-HD left- and right-eye images are accurately synchronized to create FULL HD 3D images.

6-Mode Gamma includes "Cine-like" mode
Drawing on technologies developed for the VariCam, Panasonic has equipped the AG-3DA1 with advanced gamma functions that address six different shooting scenarios and enhance your creative abilities.
AG-3DA1 Gamma Modes

Advanced Image Adjustments Built-In
• Matrix Tables: Enable quicker color settings for each scene, with three modes: NORM1, NORM2 and CINE-LIKE.
• Knee point settings: Low, Mid and High
• Adjustable H detail level, V detail level, and detail coring
• Adjustable chroma level, chroma phase, color temp and master pedestal

High Image Quality Color Viewfinder and LCD
The AG-3DA1's color EVF uses a 1.14 cm/0.45 inches approx. 1,226,000 dots-equivalent (852 x 480 x 3 [RGB] ) LCOS (liquid crystal on silicon) display panel. This system delivers bright, detailed, high-resolution images and a high response speed. The AG-3DA1's LCD monitor is a 8.13 cm/3.2 inches panel with a 16:9 aspect ratio. With approx. 921,000 dots (1920 x 480), it boasts high resolution.

Color Viewfinder
Focus Assist Functions
The AG-3DA1 has a focus ring for manual focusing, much like a conventional 2D camera recorder. As a focus assist function, a focus bar is displayed on the LCD monitor and viewfinder. The AG-3DA1 also features a PUSH AUTO button that temporarily activates the auto focus function.

Simplified Waveform and Vectorscope Display
The AG-3DA1 has waveform and vectorscope display functions of the captured video signal on the LCD monitor.
* for only Left channel signal in camera mode.
Two User Buttons
The AG-3A1 allows four functions (listed below) to be assigned to two user buttons. Assigned functions can be accessed at the touch of a button.
Assignable Functions

Other Professional Camera Features
• White balance: Two memories (A/B) and Preset (3200K or 5600K).
• Mode check: Displays a list of the camera settings on the viewfinder and monitor.
• Zebra: Select any two levels from among 50% to 105%.
• Color bar and 1 kHz test-tone output.
• Tally lamps: Provided on the unit's front and rear.

Superb Mobility for Low-Angle Shots
Lightweight camera body weighs 2.4 kg (5.3 lb.) approximately. The upper part of the handle grip contains both the Rec Start/Stop button and a lens zoom control (with three speeds). This design assures easy shooting even at low angles. The excellent mobility of the AG-3DA1 allows flexible camera angles that are not possible with other 3D cameras.

The file-based recording system and digital interface achieve a comfortable 3D image production workflow
File-Based Recording to Two Memory Cards
Using the two Left/Right memory card slots, the AG-3DA1 records left-channel and right-channel full-HD images simultaneously to two SD/SDHC Memory Cards. The solid-state memory card ensures high reliability and withstands operating temperatures of –25°C to 85°C (-13°F to 185°F). This enables use in harsh temperatures and fluctuating humidity. It is also free of dropouts and head clogging. With memory cards, there is no need to search for a blank space to record. Data is automatically recorded in an available space. This eliminates accidental overwriting of existing data. After shooting, recorded clips can be previewed or deleted immediately. After recording, data can be uploaded to editing software without digitizing. SD/SDHC Memory Cards are inexpensive and can be easily purchased in local markets.
* Use SDHC/SD Memory Cards of Class 4 or higher. SDXC cards cannot be used. HD Multi-format Recording
Multi-format HD recording in the AG-3DA1 responds to a host of 3D content production needs and worldwide applications. It supports the following HD video formats. The maximum recording time is approximately 180 minutes in each mode (when two 32 GB SDHC cards are mounted in the Left/Right slots).
AG-3DA1 series Recording Format

* In Native mode, the AG-3DA1 records only active frames. AVCHD PH Mode for FULL HD 3D Recording
The AG-3DA1 records in AVCHD PH mode, based on MPEG-4 AVC/H.264 High Profile, which is the latest video compression technology. With more than twice the compression efficiency of MPEG-2 (such as in HDV), AVCHD provides both high image quality and a low data rate. PH mode was developed by Panasonic exclusively for AVCCAM professional video production. Boasting 24 Mbps (average: 21 Mbps), which is the maximum bit rate for the AVCHD format, the AG-3DA1 records 1920 x 1080 full-pixel HD images. The multi-slice feature of the PH mode also helps to speed up processing by nonlinear editors that are equipped with multi-core CPUs, by using parallel processing to take full advantage of the CPU power.

Sample comparison: When a flash causes large contrast differences and reduces correlation of consecutive image, HDV shows considerable block noise, while AVCHD in the PH mode minimize break-up.
Comparison of HD Recording Formats
Versatile Solid-State Recording Functions
• Thumbnail View for easy playback or deletion of clips displayed on the LCD monitor
• Shot mark: Allows convenient OK and NG marking, and can be added to each clip during or after recording.
• Rec check: You can check the end of the most recently recorded clip with one-touch ease.
Clip Metadata Function
You can create a metadata upload file (produced with AVCCAM Viewer software) containing information such as clip name, the name of the camera operator, the recording location, and text memos on an SD/SDHC card, and load it as clip metadata. This information will be very useful when it comes to editing the project and quickly finding the right clip to place on the timeline.
Professional-Level Audio Input
The AG-3DA1 is equipped with two audio input channels for digital audio (Dolby Digital) recording. The AG-3DA1 also comes equipped with a built-in stereo microphone and with XLR-type audio input terminals (2 channels, mic/line switchable, 48 V compatible) on the rear panel. You can switch audio channels 1 and 2 separately to either line or front mic input. Large level adjustment dials are easy to operate and offer high visibility.
SMPTE Time Code Generator/Reader
The built-in SMPTE time-code generator/reader lets you select the Drop Frame/Non-Drop Frame and Free Run/Rec Run modes, preset and regenerate. User bits are also provided.
HD SDI Simultaneous Output with Sync-Rec Function
HD SDI Left/Right terminals on the AG-3DA1 allow camera-through or playback left-channel/right-channel FULL HD 3D image output (simultaneous). This enables 3D images to be monitored on a BT-3DL2550 3D Video Monitor. When the external recorders/recorder are/is connected, line recording of camera-through FULL HD 3D video signals is also possible.
HDMI 1.4a Output
The AG-3DA1 features an HDMI 1.4a output terminal*1 that outputs FULL HD 3D video signals for viewing on 3D VIERA and Panasonic 3D plasma displays.*2 This terminal outputs camera-through signals or left-channel/right-channel FULL HD 3D playback signals.
*1: HDMI output and HD SDI output cannot be used simultaneously.*2: Professional 3D Plasma Display is scheduled for release in Autumn of 2010. Please refer to the latest Professional 3D Plasma Display Information at Panasonic website.
3D Compatible Camera Remote
The camera remote terminal allows remote adjustment of the convergence point in addition to the focus, iris, zoom and REC start/stop.

The high-precision HD twin-lens system allows easy acquisition of natural-looking 3D images.
3D Acquisition System
Connecting the BT-3DL2550 3D LCD Video Monitor via HD SDI Dual-Link lets you view the stereo image so that you may adjust the 3D image to create the effect you want by varying the focus and convergence point.
3D Content Editing System
3D video data recorded by the AG-3DA1 can be editedby a computer-based (Windows/Mac), low-cost nonlinear editing system installed with a 3D editor plug-in (third-party software, sold separately)* that supports existing AVCHD-compatible video editing. The use of files allows easy ingestion to a computer, much in the same way as in ordinary 2D image editing. The addition of the 3D plug-in also lets you adjust the 3D images. This plug-in produces a DVI-D video output so that images can be viewed and checked using the BT-3DL2550. Editing results can be saved in an external storage unit for handover to the subsequent process (MA/Blu-ray 3D™ authoring, etc.).

فیلمنامه نویسی 5

دیگر برف نمی بارد. پنجره اطاق کوچکم آسمان را با ستاره هایش قاب  گرفته است. لحظه ای به آسمان خیره می شوم. ستاره ها انگار آسمان را چراغانی کرده اند. به کنار میز بر می گردم و نشانگر ماوس را می کشم پایین - روی استارت  کلیک می کنم. و بعد شاوت داون. به دفتر یاداشتم کنار کتاب ها ی روی میز نگاه می کنم. صفحه اش هنوز هم سفید است. چراغ روی میز را خاموش می کنم .
در راهرو تاریک را که باز می کنم نور خورشید می افتد روی صورتم. آفتاب چشمم را می زند. عینک آفتابی ام را می زنم و از خانه  می آیم بیرون .  
تو راه می افتی پشت سرم و اصلا  به من محل هم نمی گذاری.  من هم به تو سلام  نمی کنم.
نگاه سرد مردم توی سوپر مارکت واحساس اینکه فروشند ه ها تو را تحت نظر دارند باعث می شود زودتر خریدم را بکنم و بایستم توی صف صندوق برای پرداخت. آنطرف صندوق مردی با نشان دادن کارت شناسایی - کیف یکی از خریداران خارجی را بازرسی می کند. همکار دیگرش درب ورودی را می بندد و هنوز نوبت پرداخت من نشد که پلیس های تنومندی وارد سوپر مارکت می شوند.
تو کمی جلو تر از من از کنار ماشین پلیس رد می شوی و من لحظه ای می ایستم و به ماشین پلیس خیره می شوم. نا گهان احساس می کنم ایده ای  برای نوشتن پیدا کرده ام.
یک اتفاق می تواند تولد یک ایده باشد. یک شخصیت جالب و حتی یک مکان بخصوص نیز به ما ایده برای نوشتن می دهند. البته عمق نگاه ما و وسعت دیدمان تعین کننده نوع برداشت ما از آن واقعه - شخصیت - مکان و یا هر چیز دیگر است. سپس ما به تخیل و دانش یا فن نوشتن نیاز داریم. برای تمرین بد نیست به عکسی که دوست دارید نگاه کنید و یک صفحه در باره آن و احساسی که به آن دارید بنویسید. دقیقا همان کاری که من اکنون باید در رابطه با واقعه ای که شاهدش بودم انجام بدهم. در اولین مرحله  - خود واقعه را در چند جمله ساده می نویسم. سپس آنچه که باعث شد تا این واقعه برایم بیشتر از یک اتفاق عادی جلوه کند را نیز ذکر می کنم. و در ادامه احساسم را در آن رابطه می نویسم و حالا آنرا در ارتباط  یا  در مقابل با وقایع دیگر قرار می دهم. حالا نظرم را در این رابطه یاداشت می کنم. در واقع یک تحلیل چند خطی که داستان - شخصیت و نتیجه کلی یا  پایان نه چندان دقیق آنرا برایم روشن می کند

دوربین جی وی سی JVC GY-HM 790 مناسب تولیدات تلویزیونی

 

شرکت جی وی سی اعلام کرد به خریداران دوربین JVC GY-HM 790  پانصد یورو تخفیف می دهد.  GY-HM 790 که قابلیت های بیشتری نسبت به GY-HM 700  دارد مانند برادر کوچکش اقبال خوبی برای فروش نداشته است. تولیدات متنوع و بسیار مناسب شرکت های رقیب در سال جاری که بزودی وارد بازار می شوند فروش این دوربین مناسب برای تولیدات تلویزیونی متوسط را تحت الشعاع خود قرار داد. شاید بهمین خاطر جی وی سی بیشترین تبلیغ اش را برای فروش این دوربین به قابلیت ضبط استودیوئی و  رپرتاژ آن معطوف داشته است.  این دوربین 11000 دلاری (با یک عدد لنز کانن) با قابلیت های خوبی مانند 35 Mbps و FULLHD- 422  باز هم برای رقابت کمی  گران بنظر می رسد.

Performance


Designed to Achieve Higher HD Picture Quality with JVC's Advanced Technologies
The GY-HM790 utilizes three precisely aligned 1/3-inch progressive scan full HD CCDs—one each for red, green and blue primary color—and outputs full resolution in both 720p and 1080i/p. JVC's advanced ProHD capture technology incorporates a new patent-pending Adaptive Pixel Correlation Technique (APCT), and combined with TRIPLEX Offset Technology delivers exceptional resolving power comparable to cameras with larger image sensors. The highly efficient ProHD form of H-V pixel shift, where the Blue pixels' sensor array is shifted ½ pixel horizontally, while the Red pixels' sensor array is shifted ½ pixel vertically (both referenced to the Green array), enables recovery of additional luminance detail between the photosites of each pixel. By applying the Adaptive Pixel Correlation Technique, the camera achieves a remarkable improvement in image texture and resolving power in the 1080i/p modes. The TRIPLEX/APCT system differentiates between "object directions" in high frequency areas of the image, to the extent vertical, horizontal, diagonal (left) or diagonal (right), and then applies pixel compensation for lost pixels in high frequency areas. Furthermore, using a global shutter, the design minimizes wobbling during quick pans and fixed pattern noise in low light conditions, contributing to a more stable image.

JVC Original 35Mbps MPEG2 Encoder
Drawing from its experience in developing rack mount encoders used by major television stations, JVC developed a proprietary codec capable of providing highly efficient compression up to 35 megabits per second, a bitrate that can support full 1920 x 1080 sampling. This results in recorded images of exceptional quality. MPEG2 long GOP is the most widely accepted broadcast standard compression supported by all popular editing systems and broadcast servers. In the HQ mode, the encoder operates with a variable bit rate average of 35Mbps. The SP mode records at a constant bit rate of either 19.7Mbps or 25Mbps to ensure compatibility with a wide range of equipment. The GY-HM790 supports all major signal formats including 1920 x 1080, 1440 x 1080, 1280 x 720, and 720 x 480.

Variable Frame Rate Recording (Over crank, Under crank)
When recording in the 720p 35Mbps mode, the camera can be set to record at a frame rate different than the playback rate. This capability makes it possible to record slow or fast motion when the recording is played back at 24p or 30p.

Standard Definition Recording Capability
Responding to the needs of the industry, the GY-HM790U, in addition to its capability as an HD recorder, offers Standard Definition recording for maximum flexibility. Recording in SD provides a time-saving alternative to down-conversion of HD material for SD broadcasts, which is still an industry standard in many countries worldwide. This feature offers a fundamental advantage for professionals with time-sensitive SD workflows.

High performance Canon HD lens
The GY-HM790U includes a detachable 14x Canon KT14x4.4KRSJ HD lens based on the superb optics found in more expensive HD lenses. Its superior MTF provides higher resolution than typical "stock" lenses. The lens has improved lateral and longitudinal chromatic aberration characteristics and is ideal for full 1920 x 1080 imaging. Canon's internal focusing system minimizes "breathing" compared with typical focusing systems. Internal focus also makes possible a more efficient light blocking lens hood. ENG shooters will be pleased with its wider angle and consistent brightness from 4.4mm (wide) to 62mm (telephoto) with no F-drop. Operation is the same as with all professional lenses, with mechanical control of focus, and servo or manual control of zoom and aperture. In addition to the GY-HM790's standard detachable 14x Canon lens, numerous lens options are available from JVC including the 13xTh13x3.5BRMU wide angle Fujinon zoom lens, a new 17x XT17sx45BRMK1 Fujinon zoom lens, 18x HTs18X4.2BRM Fujinon zoom lens, 20x KT20X5BKRS Canon zoom lens, and adapters that allow ½-in and 2/3" bayonet mount lenses to be used. Add the HZ-CA13U film lens mount adapter to the 1/3" bayonet mount, to enable mounting of 16mm film camera lenses to the GY-HM790, greatly expanding production lens options. The camera features an "image flip" function that corrects for the inverted image produced by prime lenses.

Secure Digital High Capacity (SDHC) memory card recording
The GY-HM790 records on widely available SDHC Class 6 or Class 10 memory cards, presently available in capacities up to 32GB. The camera provides 2 memory card slots, for a total of up to 64GB of on board storage—enough for more than 6 hours* of continuous HD recording. The camera automatically begins recording on the second card when the first card fills up. When the second card fills up, the camera will revert to recording to the first card slot, allowing for virtually unlimited recording lengths. Class 6 or Class 10 cards are required. If a class 2 or 4 card is inserted, a warning indicator will be displayed. Being able to quickly switch cards with dual slots is invaluable in a breaking news situation where a producer may wish to begin editing while the shooter is still capturing footage. *When recording in 19Mbps mode
Separate flip open covers protect card slots from dust, moisture and open separately for each card. If a cover is opened while the card is being recorded on, a warning message is displayed on the VF/LCD. SDHC cards are economical, highly reliable, and make possible a recording system that consumes up to 20% less power than tape or HDD based systems. The per-minute cost of SDHC memory is comparable to professional video tape. Moreover, SDHC media is the first practical solid state solution to physical archive.

Native File Recording
The GY-HM790 incorporates JVC's Native File Recording technology that stores video in the ready-to-edit file formats used by Apple's Final Cut Pro™, Adobe Premiere™, and other popular non-linear editing systems. The HD and SD ".mov" files created in the camera can be easily dragged onto Final Cut Pro's or Premiere's timeline or clip bin without conversion or rewrapping, saving time while keeping the recorded material first generation. There is no need to use an intermediate codec. For users of other NLE systems, including solutions from Avid, Canopus and Vegas, the GY-HM790U supports the MP4 file format which can edited without re-encoding. HDV-compatible M2T files can also be created from these MP4 files using the ProHD Clip Manager. 4:2:2 uncompressed digital video is provided via HD-SDI output for recording onto an external recorder. For standard definition applications, in addition to .mov format files, the GY-HM790 creates popular type-2 AVI files that imports easily into most current and legacy NLE systems. *1 Play back compatibility not guaranteed on different types of products due to variation of supported recording mode. *2 MP4 is the compliant file format used on the XDCAM EX™ *3 SxS is a flash memory card designed for professional video cameras with a high-speed PCI Express interface.

Optional SxS Media Recorder
The optional SxS media recorder allows simultaneous shooting to SDHC and SxS media providing instant backup or archival recordings. This compact recorder attaches directly to the GY-HM790 without an adapter. The compact media recorder provides status information on its built-in LCD screen as well as on the camera's viewfinder. Recorded video on the SxS cards can be played back on the camera's LCD monitor or viewfinder.

Pre Rec (Retro Cache) Start Mode—No more missed shots!
In this mode, the GY-HM790 continually records up to 20 seconds in cache memory. When the trigger is pressed, the live signal is appended to the cache recording, giving the shooter a head start in getting the shot. This feature is invaluable in capturing breaking events when the shot would be lost before a traditional camera could begin recording. When Pre Rec is activated, a "P" will be displayed in the viewfinder and on the LCD monitor.

Continuous Clip Mode
In this mode, the GY-HM790 creates a single clip file from multiple trigger presses. This is ideal when "in camera editing" is preferred. The complete shot sequence is instantly available as a single clip. When recording in the Continuous Clip Mode, time code can be either free run or in the REC mode.

JVC ProHD Clip Manager
The ProHD Clip Manager for both Mac and Windows makes it easy to manage MP4 clips on the GY-HM790U's memory cards from your computer. With a few clicks of the mouse you can copy, move or delete clips, preview clip content, as well as view and edit clip metadata. A thumbnail view of all the clips in the current folder shows the content of each clip at a glance. Use the viewer to watch the whole clip, or change the clip's index frame used for the thumbnail. You can also manage folders to keep your clips organized, and check the remaining free space on a card. The latest version of ProHD Clip Manager offers an even greater level of NLE compatibility by enabling MP4 files to be converted to m2t widely supported by NLEs.

ProHD Log and Transfer Plug-in
The ProHD Log and Transfer Plug-in is a software for Apple's Final Cut Pro™ that lets you drop MP4 files recorded on the GY-HM790U into the clip bin of Final Cut Pro™. With the plug-in installed, you can view thumbnails of the MP4 files on a memory card from the Log and Transfer screen of Final Cut Pro™. Simply drag and drop the thumbnails into the bin to automatically convert the clips to QuickTime™, ready for use.
Unsurpassed Versatility


Compact Shoulder Form Factor
Weighing only 8.2 lbs including lens, viewfinder, microphone and battery, the GY-HM790 rests comfortably on the right shoulder providing stable, steady shots. Unlike some oversized hand held models, the GY-HM790 becomes part of the shooter similar larger cameras but without the fatigue associated with them. The handle has been redesigned for better carrying balance, and to accommodate wearing gloves in cold weather.

High resolution LCOS viewfinder
The GY-HM790 is equipped with a new, rugged high resolution viewfinder based on a new .45-inch 1.22 million pixel Liquid Crystal on Silicon (LCOS) panel (852 x 480 x 3). This new all-digital viewfinder displays images with more than 5 times the resolution of typical color viewfinders. Its sturdy reinforced die-cast aluminum chassis and LED light source ensure years of trouble-free operation. A serial digital interface means there's no quality loss, even with razor sharp graphic overlays. The viewfinder's native aspect ratio is 16:9. Safe area indications are available for popular aspect ratios including 2.35:1. In the record mode, audio level indications, battery remaining "fuel gauge" (when using digital batteries) and estimated time remaining for each memory card are displayed in the viewfinder. The Zebra function now offers 2 patterns (selectable.)

Jumbo size 4.3-inch flip-out LCD panel
Complementing the new high resolution viewfinder is a large LCD flip out monitor that can be used in recording, playback, clip management, and menu operation. The 4.3-inch 800x480 WVGA LCD offers a 16:9 aspect ratio and provides a wide array of monitoring and setup indications. It is specially designed to reduce surface reflections and glare to maintain a clear, visible, bright view during outdoor recording. Menu items are easily selected using user-friendly setting cross keys. Cross-key control makes menu navigation a breeze. The interface is very intuitive, with up down/left-right buttons on the same control disk. Selections are made by pressing the center of the disk. When in the camera mode, a blue LED lamp outlines the disk. When in the media playback/management mode, the color changes to green. A Red display indicates that the camera is in the USB or IEEE-1394 (slave) mode. (The LED can be turned off with a menu choice.) Extensive image customization is available. Thanks to the oversize monitor screen, the user see changes to the image as the setting is being made, eliminating guesswork. Individual user settings are stored on an SDHC card and may be restored to any GY-HM790 or GY-HM700 camera.

Built-in Clip View & Management Functions
When the camera is switched to the playback mode, a clip viewer appears on the large LCD monitor and in the VF. (This signal may also be output through the HD/SD SDI connector.) Clips are identified by time code and with a user defined filename with numeric increments. Detailed information is displayed about each clip including recording format, resolution, and time code start/stop, user bits, and creation date/time. Clips can be protected from accidental deletion or deleted if no longer needed. Damaged clips (due to improper eject, etc.) may be repaired with the "restore file" function. Though no special formatting is required, memory cards can be re-initialized in the GY-HM790 to an empty state even while the other card is recording. The Quick Review function is available in the record-pause mode and allows the videographer to play back the first 5 seconds or the last 5 seconds of each clip, or the entire clip. After playback, the last image is retained (freeze) until the menu is reactivated. If during Quick Review, the record trigger is pressed, playback stops and recording begins immediately.

Spot Exposure Meter
When shooting very high contrast scenes, the Spot Meter can be a very useful tool, letting the videographer monitor the dynamic range of an image on the LCD/VF and adjust the exposure of an object in the frame. There are 4 modes of spot metering: Max/Min, Max, Min, and Manual. In the Max/Min mode, the highest and lowest levels of the image are identified with color markers, red (H) and white (L), along with the video level (before knee & gamma). The same values can be obtained individually with the Max and Min settings. Manual lets the videographer set the portion of the image to monitor. For example, in a scene with varied illumination, the videographer may wish to meter an individual's face, and set the exposure accordingly. As the scene changes, the exposure can be corrected precisely to the desired subject.

Uncompressed Audio Recording with Full Manual Control
The GY-HM790U captures audio with the same uncompromising quality as video. Two-channel 16-bit/48 kHz uncompressed linear PCM (linear pulse code modulated) audio channels are recorded via the detachable shotgun microphone, or via a pair of balanced XLR connectors. Versatile input switching and independent channel assignment allow both mic and line-level sources (such as wireless receivers) to be connected, and phantom power is available on each XLR connector independently. Audio recording levels are controlled automatically or manually, with an audio level meter in the viewfinder and LCD monitor for easy monitoring.

Patented "FOCUS ASSIST" function
Achieving exact focus with HD signals is critical. JVC's Focus Assist turns focusing into a fast, easy and accurate process. When Focus Assist is activated, the picture in the viewfinder becomes monochrome and all objects which are in focus take on a colored edge. Focus Assist works equally in the viewfinder as well as on the LCD panel. The Focus Assist function can be invoked by pressing the dedicated button on the control panel, or assigned to the RETURN button on the lens.
Connectivity


HD/SD SDI, IEEE1394 Output
For live broadcast applications, or for monitoring, the GY-HM790 provides an uncompressed, 4:2:2 full HD or downconverted SD signal via its HD/SD SDI connector. The signal can come from either the camera or from memory playback. When downconverted, the video may be in either PAL or NTSC depending on the HD mode selected: 60Hz (23.98p, 29.97p, 59.94p/i) = NTSC, 50Hz (25p, 50p/i) = PAL. When 23.98p modes are selected, it will contain Varicam™ flags (720p24 mode only) to facilitate post production. The HD/SD SDI output is via a BNC connector and includes embedded uncompressed audio. It is also possible to output the menus and clip viewer via the HD/SD SDI output. The IEEE1394 output is via a 4-pin connector and can also be switched between HD and SD. The audio output is HDV compliant in HD mode and DV compliant in SD mode.

Genlock / Aux (Pool feed) Input
For multi-camera productions, the GY-HM790 provides a genlock input. The same connector can be switched to an auxillary SD video input (standard definition), useful for recording composite pool feeds from other cameras. Recordings from the pool feed are made in the DV (.avi) or MOV format.

Time Code In/Out
Time codes can be preset from within the GY-HM790's menu, or can be input from an external time code generator, useful in isocam recording applications. The GY-HM790 can also be used as a master TC generator, providing a time code output for other cameras or audio recorders to synchronize to.

Component or Composite Video Output (selectable)
Component HD signals can be output via the BNC connectors on the camera. The signal will always be in the format being captured or played back. (Cross converting to another format is not possible.) If a downconverted composite signal is desired, the output can be switched to provide NTSC (when HD is 23.98p/29.97p/59.94p/i) or PAL (when HD is 25p, 50p/i) signals. Downconverted composite signals can be especially useful when providing an SD feed for a live webcast while simultaneously recording full HD. The composite output can also be provided when playing back recorded high definition material.

Simultaneous DV/HDV Output via IEEE-1394
Downconverted standard definition DV signals are available through the 4-pin IEEE-1394 connector. These signals can be recorded on most "Firewire" recorders, including the DRHD100GB100 dockable HDD recorder. Again, these signals will be in either the NTSC or PAL mode depending on the HD mode selected (60Hz or 50Hz) and can be output while recording full high definition to the built-in SDHC memory cards, or when playing back HD material. When an SP high definition mode is selected (either 19.7Mbps or 25Mbps), the camera can also output an HDV transport stream compatible with the MR-HD100 through the IEEE-1394 connector.

KA-790 Studio Sled
KA-790 is a mechanical adapter for studio use for GY-HM790 and KA-M790. It supports the VF-HP790 LCD studio viewfinder on the top and stabilizes the entire system including an optional teleprompter. A hinged side panel makes it easy to remove the camera for shoulder use.

VF-HP790 LCD Studio Viewfinder
The VF-HP790 is an 8.4-inch XGA (1024x768 pixels) LCD studio viewfinder designed to work with GY-HM790 or the GY-HM700. Designed to mount to the KA-790 Studio Sled, it is equipped with a large tally indicator, and screen hood. A fully digital interface provides all of the camera's viewfinder indications: safety markers, focus assist, power and clip management. The VF-HP790 is also provided with an HDSDI input for monitoring an external signal.

KA-M790 Multi-core studio interface unit
The KA-M790 is a small and compact interface unit that enables Studio/EFP operation. It differs from the interface used with the GY-HD250 system in that all studio functions are now contained within a single unit attached to the camera body. The GY-HM790/KA-M790 system is now more mobile for EFP applications.

Remote Camera Control Connector
A 6-pin remote connector provides a TTL interface to an optional JVC RM-LP25U, RM-LP57U, or RM-LP55U control unit. Extensive control options are available including shading, paint, iris, gamma level, knee, gain, shutter and black level. Functions vary with each unit.
