MPEG to VOB Conversion FAQ
What does the MPEG to VOB converter do?
+
It transcodes a MPEG video into the VOB container. Resolution, frame rate, and aspect ratio are preserved by default — useful when you need a different format for a target player without quality loss.
Will resolution and frame rate be preserved in the VOB?
+
Yes. MPEG → VOB keeps resolution, frame rate, and aspect ratio unchanged by default. To change them, use the Resize or Speed tool on the result.
Will the MPEG play smoothly on modern devices after converting to VOB?
+
Yes. Legacy MPEG files often fail to play in modern browsers and on iOS / Android. VOB uses widely supported codecs that play natively on phones, tablets, smart TVs, and every modern browser.
Will the converted VOB be a different size than the MPEG?
+
Modern codecs compress better, so VOB from a legacy MPEG is typically 30-60% smaller at equivalent quality. Conversions in the opposite direction can grow the file.
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. 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.
What should I watch for converting an MPEG from a disc or a broadcast recording?
+
Interlacing and aspect ratio, in that order. Material made for television is interlaced almost without exception, so deinterlacing has to be on or every moving edge arrives combed; and a great deal of it is stored as non-square pixels with a flag saying how wide to display it, which a converter that ignores the flag turns into a stretched or squashed VOB. Check the first few seconds of the output before running a batch — both faults are obvious immediately and invisible in the settings.
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.
Is there a file-size limit when converting MPEG to VOB?
+
Anonymous uploads are capped at a generous default; signed-in free accounts get a higher cap, and Pro accounts have no per-file limit. Browser memory is usually the practical constraint long before our server-side limits kick in.
Can I batch-convert several MPEG files to VOB at once?
+
Yes. Drop or pick multiple MPEG files in one upload — the converter processes them in parallel and returns a ZIP of the VOB results. There is no need to repeat the upload step per file.
What happens to my MPEG files after the conversion?
+
Uploaded files and VOB outputs are auto-deleted after a short retention window. We do not inspect, share, or train on user files. Direct download links are time-limited and tied to your session.
