dvgrab is part of kino, so here is kino's description:
Kino is a non-linear DV editor for GNU/Linux. It features excellent integration with IEEE-1394 for capture, VTR control, and recording back to the camera. It captures video to disk in RawDV and AVI format, in both type-1 DV and type-2 DV (separate audio stream) encodings.
You can load multiple video clips, cut and paste portions of video/audio, and save it to an edit decision list (SMIL XML format). Most edit and navigation commands are mapped to equivalent vi key commands. Also, Kino can load movies and export the composite movie in a number of formats: DV over IEEE 1394, Raw DV, DV AVI, still frames, WAV, MP3, Ogg Vorbis, MPEG-1, MPEG-2, and DivX. Still frame export uses Imlib1, which has built-in support for PPM, JPEG, PNG, TIFF, GIF, and whatever your ImageMagick installation supports. MP3 requires lame. Ogg Vorbis requires oggenc. MPEG-1, MPEG-2, and DivX require mjpegtools 2.0.0.
