VOB to MPEG Conversion FAQ
What does the VOB to MPEG converter do?
+
It transcodes a VOB video into the MPEG 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 MPEG?
+
Yes. VOB → MPEG keeps resolution, frame rate, and aspect ratio unchanged by default. To change them, use the Resize or Speed tool on the result.
Will the VOB play smoothly on modern devices after converting to MPEG?
+
Yes. Legacy VOB files often fail to play in modern browsers and on iOS / Android. MPEG uses widely supported codecs that play natively on phones, tablets, smart TVs, and every modern browser.
Will the converted MPEG be a different size than the VOB?
+
Modern codecs compress better, so MPEG from a legacy VOB is typically 30-60% smaller at equivalent quality. Conversions in the opposite direction can grow the file.
Can VOB be converted to MPEG without re-encoding the video?
+
Yes, and it is the fast path. VOB and MPEG 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. 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. MPEG here means an MPEG-1 or MPEG-2 program stream, the format standardised for Video CD and then for DVD and broadcast television.
My VOB recordings are split into numbered parts — does MPEG 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. MPEG 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 cannot stay selectable, because MPEG has no soft-subtitle stream to hold them. There are two ways out: burn them into the video during conversion, which makes them permanent and unstyleable, or export them as a separate .srt alongside the MPEG for the player to load. The converter tells you which it did rather than dropping them silently. 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.
What should I watch for converting a VOB 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 MPEG. Check the first few seconds of the output before running a batch — both faults are obvious immediately and invisible in the settings.
Why does my VOB file fail to convert to MPEG?
+
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 MPEG?
+
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.
Is there a file-size limit when converting VOB to MPEG?
+
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 VOB files to MPEG at once?
+
Yes. Drop or pick multiple VOB files in one upload — the converter processes them in parallel and returns a ZIP of the MPEG results. There is no need to repeat the upload step per file.
