VOB to TS

Pulling the soundtrack out of a .vob video into .ts audio keeps what you can hear and drops the picture entirely. A .vob file is a Video Object from a DVD's VIDEO_TS folder, holding the disc's actual movie data. Each .vob multiplexes MPEG-2 video, audio, subtitle subpictures, and navigation commands, split into pieces of about one gigabyte to satisfy the DVD specification.
A .ts file is an MPEG transport stream, the packetized format built to carry television through unreliable channels like antennas, satellites, and cable. DVR recordings, IPTV captures, and HLS streaming segments all use .ts, making it one of the most common raw broadcast formats people encounter. For this route the practical draw is corruption costs a fraction of a second, not the whole file and trivially concatenable without remuxing — balanced against packet overhead runs several percent above an equivalent MP4, which is worth knowing before you commit a large batch.
Why convert VOB to TS?
The usual reason to take .ts audio out of a .vob file is that only the sound matters — a talk, interview, song, or podcast segment. Keeping the video stream would waste storage, and a dedicated audio file is easier to trim, tag, and play. On the source side, files split at roughly 1 GB boundaries and must be rejoined for continuous playback; on the target side, the payoff is corruption costs a fraction of a second, not the whole file, which is exactly what you want for saving recordings from DVRs and set-top boxes.
VOB vs TS at a glance
| Aspect | DVD video object (.vob) | MPEG transport stream (.ts) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Container — quality depends on the codecs and settings inside |
| How it stores data | an MPEG-2 program stream variant extended with navigation packs (PCI/DSI) that DVD players use for menus and seeking | fixed 188-byte packets with sync bytes and continuity counters allow receivers to detect and skip corrupted data |
| Strongest at | backing up home-movie DVDs before the media degrades | saving recordings from DVRs and set-top boxes |
| Weak spot | files split at roughly 1 GB boundaries and must be rejoined for continuous playback | packet overhead runs several percent above an equivalent MP4 |
| Metadata | none inside the VOB itself; titles, chapters, and menu logic live in the accompanying IFO files on the disc | broadcast service tables (SDT/EIT) can carry channel names and program-guide data, but there is no field for user tagging |
Pick TS as the output
Select .ts in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if TS is selectable, the route is real and validated.
Convert on your device
Press Convert. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid TS file. Outputs keep the original filename with the .ts extension.
VOB to TS questions, answered
Will converting VOB to TS lose quality?
Since vob is container-oriented and ts is container-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .ts itself requires.
Is it private to convert VOB files here?
Yes — the .vob file is processed inside your browser tab and never uploaded. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded. Close the tab and the file is gone from memory.
Where will the TS file work?
VLC, ffmpeg, and every broadcast tool read .ts natively, and smart TVs often play recordings made by their own tuners. Browsers only consume transport streams indirectly through JavaScript HLS players, so standalone .ts files need conversion for the web.
Will the TS file be bigger or smaller than my VOB?
Much smaller — the video stream is usually 80–95% of a .vob file's weight, and it is discarded entirely. The remaining audio is re-encoded at the bitrate implied by your quality setting.
What happens to the metadata in my VOB file?
This converter strips container metadata deliberately (the FFmpeg command runs with metadata mapping disabled) so exported files do not leak recording details. In the source, none inside the VOB itself; titles, chapters, and menu logic live in the accompanying IFO files on the disc; none of it is transmitted anywhere because the file never leaves your browser.
Can I convert TS back to VOB?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .vob → .ts → .vob is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
