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 `.

A D2V “index file” acts as a technical guide to the stream for MPEG-2 VOB/MPG/TS content, listing which files form the timeline and how frames are arranged, including cadence or interlace hints, so AviSynth can assemble frames correctly and perform IVTC or deinterlacing with accuracy, but because it contains no actual video, moving the source files breaks its references.
Because it’s a recipe tied to specific ingredients, a D2V can fail if its source files move—renaming or relocating VOB/MPG/TS segments breaks the lookup table, since the index stores only pointers, not video; the D2V itself is a frame-by-frame map that DGIndex/DVD2AVI builds by scanning MPEG-2 sources and listing which segments form the timeline, how the stream spans multiple VOBs, and where frames sit inside GOP structures, along with flags for frame rate, aspect, and interlacing/cadence, allowing AviSynth to jump straight to correct byte ranges for stable, frame-accurate filtering and encoding, making the D2V the clean gateway into processing workflows.
From a D2V-driven workflow you can perform operations like cropping, resizing, denoising, sharpening, color/levels adjustments, subtitle burn-ins, and critically DVD-oriented steps such as deinterlacing or IVTC, after which AviSynth hands the processed frames to an encoder like x264/x265 to create MP4/MKV output, with the D2V simply ensuring frame-accurate decoding; this is why you don’t “play” a D2V—players expect actual audio/video streams, but a D2V is only a map pointing to VOB/MPG/TS sources and describing frame layout, cadence, and stitching across segments, so VLC or WMP can’t render it while DGIndex/AviSynth can use it to retrieve real frames for encoding.
A .D2V file is intended to anchor MPEG-2 workflows, letting DGIndex/DVD2AVI codify frame layout, aspect flags, and interlace/telecine cues so AviSynth can request frames reliably for cleanup tasks—crop, resize, denoise, sharpen, adjust levels, add subtitles, deinterlace, IVTC—and then encode through x264/x265, with its purpose being accuracy across multiple VOB segments.
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.
