				Input

Field mode corrects underexposed and low-contrast F.REC gamma images, and outputs monitor images with full film texture that can be used to check the lighting. There's a setting for ordinary daylight and one for

nighttime shooting.

Telecine mode is a post-processing mode that uses movie footage to produce TV content with a film-like texture (a telecine look). This mode preserves the high image quality by correcting intermediate gradation while maintaining highlights and shadows.

The Video Rec and Video modes convert images with F.REC gamma characteristics to V.REC gamma or video gamma characteristics.

CG mode is a film production mode that reverse-converts images into F.REC images after they were previously converted to telecine mode and CG-processed for production ease. Also provided is a user mode that lets you install any desired conversion table from a PC.

In addition to 720p (59.94/60 Hz), the AJ-GBX27 is compatible with 1080i (59.94/60/50 Hz) and 1080p (23.97/24 Hz) HD formats.* This makes it ideal for VARICAM recording and for editing, package production, and a host of other applications. The 12-VDC power supply (XLR 4-pin terminal) lets you take the AJ-GBX27 into the field. One HD-SDI input, two HD-SDI outputs, and an analog HD (Y/Pb/Pr) output are provided for convenient monitor connection. Make contacts let you control conversion ON/OFF from a switcher.

*This is not a format conversion function. It allows input/output of the same format only.
