AVI to VOB Conversion FAQ
How do I convert AVI to VOB without re-encoding the video stream?
+
When the AVI and VOB containers can both carry the same codec (H.264, H.265, VP9, AV1), the converter falls back to a remux: the elementary streams are copied byte-for-byte into the VOB container and only the wrapper changes. A remux of a 1 GB AVI into VOB typically finishes in 5-15 seconds with zero quality loss.
Will multi-track audio survive AVI to VOB conversion?
+
Yes — every audio track in the AVI (director commentary, alternate languages, descriptive audio) is preserved in the VOB when the target container supports multi-stream audio. MKV and MOV handle unlimited audio tracks; MP4 supports many but some hardware players only see track 1; WebM is capped at one Opus / Vorbis track.
Are subtitle tracks preserved when converting AVI to VOB?
+
Soft subtitles (selectable tracks) survive when VOB can carry them: MKV holds SRT, ASS, SSA, PGS, VobSub natively; MP4 only holds mov_text (a stripped-down format). Converting an MKV with ASS styled subs to MP4 will typically downgrade them to mov_text or burn them in. Hardsubs (burned into the video) carry over regardless.
Does AVI to VOB keep chapter markers / DVD-style navigation?
+
Chapter metadata transfers between AVI and VOB whenever both containers support a chapter atom (MKV, MP4, MOV). WebM stores chapters in a Matroska-compatible block, so MKV <-> WebM chapters round-trip cleanly. AVI has no chapter spec, so converting AVI to VOB produces an unchaptered file unless you add markers manually.
What about MKV attachments (fonts, cover art) when going AVI to VOB?
+
MKV is the only mainstream container that stores arbitrary attached files (TTF fonts for ASS subs, JPG cover art, fan-translated PDF inserts). Going from AVI to VOB drops these attachments when VOB is not MKV — the elementary streams convert, but the attached payload stays in the source. Keep AVI as a backup if you depend on attached fonts.
Which codec does the VOB output use by default?
+
The default codec is chosen to match the VOB container conservatively: MKV defaults to H.265 (HEVC) for better compression; MP4 defaults to H.264 for the widest device support; WebM defaults to VP9; AVI uses MPEG-4 ASP (DivX/Xvid lineage). Override via the advanced codec dropdown — AV1 is available for MKV / WebM where you want maximum compression and can wait through the encode.
How does HDR (HDR10, Dolby Vision) survive AVI to VOB?
+
HDR static metadata (HDR10 mastering display values, max content light level) carries through to VOB when both containers and the chosen codec support it (HEVC, AV1 in MKV / MP4). Dolby Vision is more fragile — DV profile 5 / 7 / 8.1 in AVI commonly survives only into MKV with HEVC; converting to a VOB container that does not carry the DV layer flattens to HDR10.
Will the AVI to VOB converter keep variable framerate (VFR)?
+
MKV and WebM record real per-frame timestamps and handle VFR natively, so AVI VFR survives into a VOB of those formats with no resampling. MP4 nominally stores timestamps too but some players assume CFR; the converter exposes a "force CFR" toggle that resamples VFR AVI to 24 / 30 / 60 fps VOB for problematic targets.
Why is my VOB file smaller / larger than the AVI after conversion?
+
Same-codec remux produces a near-identical size (container overhead differs by 0.1-2%). A codec change can swing the size by 50% or more: H.264 to H.265 typically halves the file at the same visual quality; H.264 to AV1 halves it again on a slow preset. Going from a high-bitrate AVI (Blu-ray rip) to a low-bitrate VOB (web upload) is the most common reason for a dramatic drop.
Does the AVI to VOB converter handle 4K / 8K / 60fps content?
+
Yes up to 8K (7680x4320) on Premium. Free tier handles 4K (3840x2160) up to the 1 GB file cap. Pure remuxes (same-codec passthrough) of large AVI into VOB are limited by disk I/O, not CPU — a 30 GB AVI typically remuxes to VOB in under a minute regardless of resolution. Re-encodes scale with pixel count.
Is my AVI file private during VOB conversion?
+
Yes — uploaded AVI files are processed in isolated workers and deleted within minutes of completion. We never view, store, retain, or share the content. See /privacy/ for the data retention window. The conversion pipeline runs on hardware we control end-to-end; no third-party APIs receive your file.
Can I trim, crop, or join AVI files during the VOB conversion?
+
Not in the same job — keep conversion focused on container / codec. Use /trim/ to clip the AVI first, then queue the AVI -> VOB step. For joining several clips into one VOB, the /merge/ tool stitches them on a per-codec basis (it remuxes when the inputs share a codec, re-encodes otherwise) and emits a single VOB file at the end.
