MPEG to VOB Conversion FAQ
How do I convert MPEG to VOB without re-encoding the video stream?
+
When the MPEG 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 MPEG into VOB typically finishes in 5-15 seconds with zero quality loss. The video is MPEG-1 or MPEG-2 with MP2 or AC-3 audio, multiplexed into a stream designed to be decoded by fixed-function hardware. A VOB holds MPEG-2 video, AC-3 or PCM audio, and DVD subpicture subtitle streams, split into 1 GB segments by the DVD spec.
Can MPEG be converted to VOB without re-encoding the video?
+
Yes, and it is the fast path. MPEG and VOB share the same underlying box structure, so the video and audio streams are copied across byte-for-byte and only the container wrapper is rewritten. Nothing is decoded and nothing is re-compressed, so a feature-length file finishes in under a minute instead of half an hour, with output quality identical to the source. MPEG here means an MPEG-1 or MPEG-2 program stream, the format standardised for Video CD and then for DVD and broadcast television. VOB is the Video Object container found in the VIDEO_TS folder of every DVD — an MPEG-2 program stream with DVD-specific navigation data added.
Can I add selectable subtitles once the file is VOB?
+
Yes. MPEG has no usable soft-subtitle track, so subtitles for MPEG content had to be burned into the picture or shipped as a separate sidecar file. VOB carries subtitles as their own selectable stream, so after conversion you can attach an SRT track the viewer can switch on, switch off or restyle.
Does VOB support chapter markers that MPEG did not?
+
It does. VOB stores chapters as container metadata, so a long recording can be navigated by section instead of by scrubbing a progress bar. MPEG has nowhere to put that information, so if the source shipped with a chapter list it was in a sidecar file — hand that to the converter and it gets written into the VOB. VOB preserves the whole DVD payload — multiple angles, multiple audio languages and subtitle tracks all survive inside it.
Is there any point converting between two legacy formats like MPEG and VOB?
+
Only if a specific piece of equipment demands the target. Both formats come from the same pre-H.264 era, so neither conversion buys efficiency, quality or future-proofing — it buys compatibility with one particular device. If the goal is to keep the footage usable long-term, convert to a current container instead of sideways. MPEG-2 needs roughly four to six times the bitrate of H.264 for the same picture, and its content is frequently interlaced, which looks combed on modern displays. VOB is split across files, may be CSS-encrypted, and carries navigation packets that confuse general-purpose players.
Will multi-track audio survive MPEG to VOB conversion?
+
Yes — every audio track in the MPEG (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 MPEG 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 MPEG to VOB keep chapter markers / DVD-style navigation?
+
Chapter metadata transfers between MPEG 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 at all, so an AVI source arrives with no chapters to carry across and an AVI target cannot store the ones it was handed; add markers manually afterwards if you need them.
What about MKV attachments (fonts, cover art) when going MPEG 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 MPEG to VOB drops these attachments when VOB is not MKV — the elementary streams convert, but the attached payload stays in the source. Keep MPEG 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 MPEG 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 MPEG commonly survives only into MKV with HEVC; converting to a VOB container that does not carry the DV layer flattens to HDR10.
Will the MPEG to VOB converter keep variable framerate (VFR)?
+
MKV and WebM record real per-frame timestamps and handle VFR natively, so MPEG 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 MPEG to 24 / 30 / 60 fps VOB for problematic targets.
