DV Video Encoder Filter

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

This filter encodes an uncompressed video stream into digital video (DV). It provides a custom interface, IDVEnc, for setting the encoding resolution and format.

Remarks

For 16-bit video (MEDIASUBTYPE_RGB555 or MEDIASUBTYPE_RGB565), the input must be 720 x 480 pixels for NTSC, or 720 x 576 pixels for PAL. For 24-bit video, there are no size constraints on the input.

The output is always 720 x 480 for NTSC or 720 x 576 for PAL; 24-bit video is scaled to fit these dimensions.
