FLV to VOB Conversion FAQ
What does the FLV to VOB converter do?
+
It transcodes a FLV 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. FLV → 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 FLV play smoothly on modern devices after converting to VOB?
+
Yes. Legacy FLV 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 FLV?
+
Modern codecs compress better, so VOB from a legacy FLV is typically 30-60% smaller at equivalent quality. Conversions in the opposite direction can grow the file.
Can I add selectable subtitles once the file is VOB?
+
Yes. FLV has no usable soft-subtitle track, so subtitles for FLV 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.
Can the VOB hold more than one audio track?
+
Yes, and it is a real upgrade over FLV. VOB treats every audio stream as a first-class track, so an original-language mix, a dub and a director commentary can live in one file with the player switching between them on demand. VOB preserves the whole DVD payload — multiple angles, multiple audio languages and subtitle tracks all survive inside it.
Does VOB support chapter markers that FLV 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. FLV 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.
Is there any point converting between two legacy formats like FLV 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. No current browser, phone or TV can play FLV — anything still in this container has to be moved out of it to remain watchable. 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 FLV 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 FLV files to VOB at once?
+
Yes. Drop or pick multiple FLV 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 FLV 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.
Will my VOB play on phones, tablets, and TVs?
+
VOB plays in most desktop players but is sometimes unsupported on mobile and TV. For broadest reach, consider MP4 instead.
