VOB to MPG Conversion FAQ
How do I convert VOB to MPG without re-encoding the video stream?
+
There is no stream-copy switch on this page. A few pairs copy a compatible video stream into the MPG container without re-encoding it, MKV to MP4 among them, which is quick and loses no quality. Most pairs re-encode the video. 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. Contents are MPEG-1 or MPEG-2 video with MP2 audio; the muxing and the GOP structure are identical to a .mpeg file.
Can VOB be converted to MPG without re-encoding the video?
+
No, not on this page. VOB and MPG share the same underlying structure, but the converter re-encodes the video for this pair rather than copying the stream, so it takes longer than a container change and the picture is compressed again. Choose High Quality under Quality to keep the most detail. 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. MPG is the same MPEG program stream as .mpeg — the three-letter extension is a DOS-era truncation, not a different format.
My VOB recordings are split into numbered parts — does MPG have the same limit?
+
No, and that is one of the better reasons to move. The VOB container has a practical single-file ceiling that long or high-bitrate recordings run straight into, which is exactly why old captures arrive as part1, part2, part3. MPG has no equivalent limit, so the pieces can be rejoined into one continuous file. VOB is split across files, may be CSS-encrypted, and carries navigation packets that confuse general-purpose players.
What happens to the subtitle tracks in my VOB file?
+
They are dropped. MPG has no soft-subtitle stream to hold them, and the converter neither burns them into the picture nor exports them as a separate file. If you need them, extract the subtitles to an .srt file with a desktop tool such as ffmpeg or MKVToolNix before converting, and load that file alongside the MPG in your player. MPG inherits every MPEG-2 limitation — heavy bitrate, interlacing, no soft subtitles — plus the confusion of two extensions for one format.
Why does my VOB file fail to convert to MPG?
+
Almost always DRM. Some VOB files are encrypted at the bitstream level by the store or software that issued them, and an encrypted stream cannot be decoded by us or by anything else without the licence key. Files you recorded, exported or downloaded unprotected convert normally; a licensed purchase will not, and no converter can honestly promise otherwise.
Is there any point converting between two legacy formats like VOB and MPG?
+
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.
Will multi-track audio survive VOB to MPG conversion?
+
Usually not. Most conversions keep one audio track, the one with the most channels (normally the main mix), re-encoded for the MPG container, so commentary and alternate-language tracks are dropped. AVI, WMV, MPEG, FLV, VOB and M4V to MKV keep every track, and so does MP4 to MOV. To keep a different track, remux the VOB with that track first (VLC or ffmpeg can do this), then convert it.
Are subtitle tracks preserved when converting VOB to MPG?
+
On some pairs. MP4 to MOV keeps every text subtitle track. AVI, WMV, MPEG, FLV, VOB and M4V to MKV keep every subtitle track: text subtitles are copied or converted to SRT, and picture-based subtitles such as DVD or Blu-ray ones are copied as they are. MP4, MOV and WebM to MKV keep only the first subtitle track (as ASS), and MP4 to WebM keeps the first one as WebVTT. Other pairs, including MKV to MP4 or MOV and WebM to MP4, drop subtitle tracks, and the converter does not burn them into the picture. Subtitles that are already burned in stay, because they are part of the video frames.
What about MKV attachments (fonts, cover art) when going VOB to MPG?
+
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 VOB to MPG drops these attachments when MPG is not MKV — the elementary streams convert, but the attached payload stays in the source. Keep VOB as a backup if you depend on attached fonts.
Which codec does the MPG output use by default?
+
It depends on the MPG container. MP4, MOV and MKV output use H.264, which plays on practically every phone, browser and TV. WebM output uses VP9. AVI, WMV and MPEG output use the older codecs those formats were designed for. MPG is the extension DVD authoring software, older camcorders and broadcast ingest tools recognise, so it stays useful for those pipelines.
How does HDR (HDR10, Dolby Vision) survive VOB to MPG?
+
There is no HDR processing or tone mapping. When the video stream is copied (MKV to MP4 or MOV with the default settings), HDR10 passes through as it is. When the video is re-encoded, the HDR10 mastering metadata is dropped and Dolby Vision or HDR10+ data is not kept, and with a Quality, Resolution or Frame Rate setting some pairs also reduce the video to 8-bit colour, so an HDR VOB can look washed out in the MPG.
