Innovation that Meets the Needs of Professionals — Ease of Operation
Ease of Operation for Complete Creative Freedom
1.22Megapixel LCOS Viewfinder and Focus Assist Function The GY-HM790U features a stunning new high-resolution (852 x 480 x 3) LCOS (Liquid Crystal on Silicon) 0.45" viewfinder. The 16:9 aspect ratio image is crisper and more detailed than conventional LCD viewfinders, with higher vertical resolution and superior RGB color separation. Helping the camera operator stay focused on the action is a focus assist system that
highlights the edges of objects in the image. Also visible in the viewfinder are indicators for the audio input level, the battery time remaining, and the recording time available on each memory card.
Focus Assist
With the increased resolution of HD, accurate focusing is critical—focusing errors that may pass unnoticed in SD video are far more obvious when watching in HD. JVC developed Focus Assist to make accurate HD focusing quick and easy. When Focus Assist is switched on, the image in the viewfinder or LCD monitor becomes monochrome and all objects that are in focus appear with colored edges. Keeping the important elements in the picture in focus while shooting is greatly simplified.
GUI
The new GUI features several improvements that make the GY-HM790U easier to use.
All on-screen monitors can be navigated intuitively via a four-way cross key and a central Set button. A colored LED ring illuminates the outer edge of the
cross keys, indicating the current camera mode. The GUI can be viewed in both the LCD monitor and overlaid in the viewfinder.
The high-resolution picture thumbnail display makes it a simple task to select clips visually for review, and more detailed file and file format, frame rate, resolution and time code data.

Shooter-Friendly Controls and Layout
The control panel of the GY-HM790U has been laid out so that all commonly used controls are within easy reach of the operator while shooting. Among the controls are three user- definable buttons that can be assigned a range of functions for instant setting.
Pre Rec Mode
How many times have you missed a crucial moment because you didn't hit the record button in time? With Pre Rec enabled,
the camcorder continuously buffers up to 20 seconds of video, so that when recording is started the cached video is included in the recorded file, giving you up to 20 second head start.
