A .D2V file is essentially a processing index created by DVD2AVI/DGIndex to outline frame positions and encoding flags for VOB or MPG/TS footage, used by AviSynth to enable accurate seeking and filtering before encoding, but it fails if source segments vanish or change paths, with its presence near DVD rips or scripted encoding assets signaling its role, and it must be used with the original media rather than opened in a player.

A D2V "index file" acts as a non-video reference sheet created during DGIndex’s scan pass, capturing GOP layout, frame order, aspect/interlace flags, and file lists so AviSynth/DGDecode can retrieve frames deterministically instead of guessing, making filtering and encoding more stable—though the index fails if the source paths no longer match.

Because a D2V is tied to filenames, shifting or renaming the source VOB/MPG/TS files causes the "recipe" to break, as all its pointers lead to outdated locations; conceptually, the file is a DGIndex/DVD2AVI-built frame map listing segment order, byte offsets, and interpretation flags—rate, aspect, interlace/cadence—so that AviSynth pipelines can decode frames in the correct sequence, apply processing cleanly, and avoid the guesswork and instability that come with seeking directly through the underlying MPEG-2 GOP chain.

A D2V enables workflow steps like cropping, resizing, noise reduction, sharpening, color/levels corrections, subtitle burn-ins, and DVD-specific IVTC/deinterlacing, after which AviSynth feeds frames to encoders like x264/x265 for MP4/MKV output, and the D2V’s role is simply frame-accurate guidance; since it stores no actual video or audio, media players can’t play it—what they need aren’t pointers but real encoded streams—whereas DGIndex/AviSynth can interpret the D2V and retrieve frames from the underlying VOB/MPG/TS files.

A .D2V file functions as a precision guide for tools that clean and re-encode video, letting DGIndex/DVD2AVI record the timeline, frame rate, aspect flags, and field/telecine cues so AviSynth can fetch frames correctly for operations like crop, resize, denoise, sharpen, levels adjustment, subtitle burn-in, deinterlacing, or IVTC, and then send them to x264/x265, making the D2V a processing aid rather than a playable file.

A .D2V "breaks" after files move because it’s a pointer file that stores exact filenames and paths for the VOB/MPG/TS set it indexed—DGIndex writes entries like `VTS_01_1.VOB`, `VTS_01_2.VOB`, etc., and downstream tools rely on those references to fetch frames, so renaming, relocating, or losing any segment leaves the D2V pointing to nowhere, causing errors or blank output; the safest fix is to keep the D2V with the full source set or simply re-index after reorganizing.
