VOB to FLV Conversion FAQ
How do I convert a VOB file to FLV?
+
Upload your VOB file using the picker above and the converter detects the source type and runs the VOB → FLV pipeline. The result downloads automatically when conversion completes; no account needed for one-off conversions.
My VOB footage shows comb lines on movement — will that carry into the FLV?
+
It will unless you deinterlace, and VOB content very often is interlaced because the format comes from the broadcast and DVD era. Interlaced frames store two half-height fields captured a fiftieth of a second apart; on a progressive-scan phone or monitor that reads as horizontal combing on anything that moves. Turn on the deinterlace option and the encoder weaves the fields into whole progressive frames before writing the FLV. 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 cannot stay selectable, because FLV 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 FLV for the player to load. The converter tells you which it did rather than dropping them silently. 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?
+
Not dependably. VOB stores multiple audio streams as first-class tracks, but FLV playback support past the first track is inconsistent, so most players will only ever expose one. Choose the track you actually want before converting; the others are better extracted to their own files than left in a container that hides them. 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.
Is the VOB to FLV converter free?
+
Yes — basic VOB → FLV conversion is free with no registration. Premium adds higher per-file size limits, more parallel batch workers, and removes ads.
How big a VOB file can I convert to FLV?
+
Free accounts: up to 100 MB per VOB file. Premium: typically 1 GB per file, depending on the VOB source type. Very large files are split into chunks server-side when the FLV format allows.
Will conversion change the content of my VOB?
+
Conversion preserves all information that both VOB and FLV can represent. Format-specific features that the FLV format doesn't support (e.g. vector data in raster output, formulas in plain-text output) are rasterized or stripped — see the format-specific notes on the result page.
Can I convert many VOB files to FLV at once?
+
Yes — drop multiple VOB files into the upload zone and they are queued in parallel. Premium has more parallel workers; on a 50-file batch this is the difference between minutes and seconds.
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.
