A .D2V file serves as a frame guide created by DVD2AVI/DGIndex to reference actual video in VOB or MPG/TS streams, recording frame positions and metadata such as frame rate, field order, and aspect flags, enabling precise seeking and stable processing through AviSynth for tasks like cropping, IVTC, or denoising before encoding, though it fails if the referenced sources are moved or renamed, and its placement near VIDEO_TS or `.avs` projects helps identify its purpose.

A D2V “index file” serves as a navigation guide to the real video by telling tools exactly where each frame lives inside the VOB/MPG/TS files, since DGIndex/DVD2AVI scans the stream and logs GOP structure, frame boundaries, and interpretation flags like frame rate or interlacing, allowing AviSynth (via DGDecode) to jump straight to the correct bytes instead of guessing—though the map breaks if source files move because the D2V only holds references, not the video itself.

Because its pointers rely on unaltered VOB/MPG/TS files, a D2V stops working if those files move or one segment goes missing, since the recipe no longer matches the pantry; the index itself is a DGIndex/DVD2AVI scan result that specifies which files form the timeline, how MPEG-2 frames spread across segments, and the precise GOP positions, along with stream metadata like frame rate and interlacing cues, giving AviSynth a dependable frame-accurate source for filtering and encoding without wrestling with raw MPEG-2 structure.

With a D2V you can run typical post-processing tasks—cropping, scaling, denoising, sharpening, color/levels adjustments, subtitle burn-ins, and IVTC/deinterlacing for DVD cleanup—then feed the processed stream to x264/x265 for MP4/MKV output, and the D2V’s entire purpose is to keep decoding stable; players can’t handle it because it holds no video or audio streams, only an index showing where frames sit inside VOB/MPG/TS files, so only tools like DGIndex/AviSynth can use it to extract the actual frames for viewing or encoding.

A .D2V file exists to give consistent frame access to MPEG-2 sources, capturing DGIndex/DVD2AVI’s interpretation of timeline and cadence so AviSynth can pull frames correctly for tasks like cropping, scaling, noise cleanup, sharpening, levels tuning, subtitle burn-ins, deinterlacing, or IVTC, then send the processed stream to x264/x265, making the D2V’s job reliability rather than playback.

A .D2V fails post-move because its role is to point to exact byte locations inside specific VOB/MPG/TS files, relying on stored filenames and paths that DGIndex captured during indexing; change those inputs and the index can no longer resolve frames, producing errors or blank video, making it essential to keep the D2V with its sources or re-index if the file layout changes.
