VOB to FLV Conversion FAQ
Is the VOB to FLV converter free?
+
Yes. One conversion an hour is free, with no account needed, for a file within the free size limit. A paid plan removes the hourly limit and the size limit, and lets you add several files to one job.
My VOB footage shows comb lines on movement — will that carry into the FLV?
+
Yes. VOB content is often interlaced, because the format comes from the broadcast and DVD era, and this converter has no deinterlace option, so the combing carries into the FLV. If it matters, deinterlace the VOB first in a desktop tool such as HandBrake or ffmpeg (the yadif filter). 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.
My VOB recordings are split into numbered parts — does FLV 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. FLV 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. FLV 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 FLV in your player. No current browser, phone or TV can play FLV — anything still in this container has to be moved out of it to remain watchable.
My VOB has several audio tracks — do they all survive into the FLV?
+
No. The converter keeps one audio track, the one with the most channels (normally the main mix), and drops the rest; there is no setting to pick a different one. To keep another track, remux the VOB with that track first (VLC or ffmpeg can do this), then convert it. VOB preserves the whole DVD payload — multiple angles, multiple audio languages and subtitle tracks all survive inside it.
Why does my VOB file fail to convert to FLV?
+
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.
Will the FLV still play smoothly on a phone or a TV?
+
It may not. VOB is decoded by dedicated silicon on phones, tablets and TVs, which is why it plays without flattening the battery. FLV typically falls back to software decoding on the same hardware — higher CPU load, a warmer device, and dropped frames on 4K material. For a device target, VOB is the safer container to stay in.
How big a VOB file can I convert to FLV?
+
Free conversions have a size limit per file, set by the type of file, and the page tells you when a file is over it. A paid plan removes that limit, so much larger files can be converted.
Can I convert many VOB files to FLV at once?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Does the VOB to FLV converter work on phones and tablets?
+
Yes — the UI is responsive and the conversion pipeline runs server-side, so mobile devices upload-then-download just like desktops. iOS and Android browser file pickers (camera roll, Files app) work end-to-end.
