Pulling the soundtrack out of a .ts video into .avi audio keeps what you can hear and drops the picture entirely. 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.
An .avi file is Microsoft's Audio Video Interleave container, one of the oldest video wrappers still in circulation. It stores video and audio in alternating chunks inside a RIFF structure, and the extension remains common on older camcorder captures and DivX-era rips. For this route the practical draw is simple, thoroughly reverse-engineered structure and virtually every desktop player and converter opens it — balanced against no streaming support of any kind, which is worth knowing before you commit a large batch.
Why convert TS to AVI?
The usual reason to take .avi audio out of a .ts 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, packet overhead runs several percent above an equivalent MP4; on the target side, the payoff is simple, thoroughly reverse-engineered structure, which is exactly what you want for playing back footage digitized from DV and Hi8 tapes.
TS vs AVI at a glance
| Aspect | MPEG transport stream (.ts) | AVI video (.avi) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Container — quality depends on the codecs and settings inside |
| How it stores data | fixed 188-byte packets with sync bytes and continuity counters allow receivers to detect and skip corrupted data | interleaves audio and video chunks inside a RIFF file, with the codec identified by a four-character FourCC code |
| Strongest at | saving recordings from DVRs and set-top boxes | playing back footage digitized from DV and Hi8 tapes |
| Weak spot | packet overhead runs several percent above an equivalent MP4 | no streaming support of any kind |
| Metadata | broadcast service tables (SDT/EIT) can carry channel names and program-guide data, but there is no field for user tagging | rIFF INFO chunks store basic fields such as title, artist, and encoding software, but nothing comparable to ID3 or MP4 atoms exists |
Pick AVI as the output
Select .avi in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if AVI 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 AVI file. Outputs keep the original filename with the .avi extension.
TS to AVI questions, answered
Will converting TS to AVI lose quality?
Since ts is container-oriented and avi is container-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .avi itself requires.
Is it private to convert TS files here?
Yes — the .ts 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 AVI file work?
Windows still opens .avi natively and macOS handles common variants through third-party players, though browsers never adopted the container. Whether a specific file plays depends entirely on the codec inside, so an old Indeo or Cinepak recording may need VLC even on Windows.
Will the AVI file be bigger or smaller than my TS?
Much smaller — the video stream is usually 80–95% of a .ts 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 TS 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, broadcast service tables (SDT/EIT) can carry channel names and program-guide data, but there is no field for user tagging; none of it is transmitted anywhere because the file never leaves your browser.
Can I convert AVI back to TS?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .ts → .avi → .ts is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
