MP4/M4V to DV: Convert Video from MP4/M4V(MPEG-4 Video) to DV(Digital Video Cassette) with River Past Video Cleaner, MP4/M4V2DV converter, conversion

What is MP4/M4V?

A video compression standard planned for late 1998. MPEG-4 extends the earlier MPEG-1 and MPEG-2 algorithms with synthesis of speech and video, fractal compression, computer visualisation and artificial intelligence-based image processing techniques.

MPEG.ORG is an excellent source for additional information on MPEG format and usage.

There are several ways to decode MP4 video. Most of the time, having Apple QuickTime installed is sufficient. Occasionally, a file is not compatible with QuickTime. You will need to install CCCP when that happens.

What is DV?

The format was first called DVC (as in Digital Video Cassette), later it was called simply DV. It is used in many consumer and professional grade digital camcorders.

Digital video (DV) can be captured from a DV camcorder, stored in a file on the user's computer, or stored on tape using a video tape recorder (VTR).

On Windows, DirectShow based DV capture program normally capture the DV into an AVI file. However, QuickTime based software would generally create a .DV file without the AVI header.

To convert video to DV, please have Apple QuickTime is installed.
