What is a D2V file?

D2V files mostly belong to DGIndex by Donald A. Graft. DGIndex, part of the DGMPGDec package, is primarily designed to create an index of an MPEG video stream, containing the location of each frame in the input stream, and some additional information about each frame. This index, or project file, is used by the companion Avisynth filter DGDecode to provide frame-accurate serving of the video via an Avisynth script. DGIndex is able to decode and index most MPEG1/2 streams including elementary streams, program streams, VOBs, VCDs, SVCDs, PVA files, and transport streams. Additional features include: video demuxing (m1v/m2v), audio demuxing (ac3, dts, aac, mpa, and lpcm), optimized iDCTs, luminance filtering, cropping, and more.
