ADVC700

Broadcast-quality Bidirectional Analogue/Digital Video Conversion

ADVC®700 is a bidirectional analogue/DV video converter with Grass Valley® PerfectSync technology to ensure impeccable conversion of every frame. A 19-inch breakout box with component video, composite, S-Video, and balanced and unbalanced audio I/O, ADVC700 offers an extraordinary set of high-end features. RS-422 signal conversion facilitates capture from professional VTRs using standard DV editing software with DV device control. Reference input and LTC time code input/output can be utilized to create a professional video editing system with editors or switchers. Locked audio prevents gaps in audio/video synchronization. The front panel includes an accessible jog dial for changing settings while viewing the LCD display.

Perfect Signal Synchronization: Grass Valley "PerfectSync"

ADVC700 not only incorporates the same video conversion technology present in the entire ADVC family of products, providing excellent reproduction of the source video footage, but also features PerfectSync technology. PerfectSync controls and synchronizes the transfer rate of IEEE 1394 communication with an external reference signal. This prevents skipped and duplicate frames and produces perfect conversion of all frames during analogue/DV conversion.

Many of the current analogue/DV converters adjust the output by skipping and/or duplicating frames in order to synchronize the DV signal to an external sync signal's frame frequency. In these converters, there is no guarantee that all input frames will output to DV accurately without frame repetition and/or frame drops. Since ADVC700 is primarily designed for studio environments, frame accuracy is essential for accurate offline/online editing. With PerfectSync, this is assured.

VTR Control by AV/C-RS422 Conversion

ADVC700 converts DV device control signals to RS422, to control an external VTR. Such control makes it possible to take in data from professional VTRs such as Digital Betacam from any standard DV editing software that features DV device control.

Professional Video System Input

Reference input and LTC input/output can be utilized to create a professional video editing system with editors or switchers.

• Reference Input
• LTC input/output
• Reciprocal TC conversions (LTC, VITC, DV TC)

Analogue Video Input Filtering

ADVC700 also features built-in analogue filtering technology to improve the quality of analogue video input during conversion. Filtering options include 3D Y/C separation, 3D noise reduction, 2D Y and 2D C noise reduction, black/white gain adjust and horizontal/vertical outline enhancement.

Proven DV Codec Technology

At the heart of ADVC700 is the innovative Grass Valley DV codec chip, providing the industry's highest picture quality preservation during analogue-to-DV conversion and locked audio support for perfect audio and video synchronization at all times.

Advanced Usability

ADVC700 is quickly configurable. The front-side dial and LCD display feature controls for Video and Audio I/O selection, aspect ratio, audio sample rates, audio delay, reference sync, RS422 control, colour bar output, PerfectSync adjustments and more. ADVC700 can operate as a stand-alone device not requiring a computer, while keeping any pre-programmed settings.
