TS to MP4

Details

How to use TS to MP4

What the tool does, how to run it, and what to expect from the result.

Why TS captures are awkward, and what this does

A TS file is an MPEG transport stream: the raw format of broadcast television, DVR and CCTV exports, IPTV recordings, and AVCHD camcorders. Transport streams are built for transmission, not playback from disk, which is why a TS seeks badly, shows the wrong duration, and gets refused by phones and editing software.

The useful fact is that most modern TS captures already carry H.264 video. This tool probes the file first, and in that common case it copies the streams straight into an MP4 container: lossless, and done in seconds. Genuinely old MPEG-2 broadcast captures fall back to a local re-encode. Either way it all runs in your browser, with nothing uploaded.

  • The streams inside the TS are probed first
  • H.264 captures rewrap losslessly into MP4 in seconds
  • Older MPEG-2 streams fall back to a local re-encode

What you get on the other side

The MP4 fixes exactly what makes transport streams painful: it seeks instantly, reports its duration correctly, plays on phones and TVs, uploads to any platform, and drops into editors without an ingest fight.

For recordings that matter, a CCTV incident, a broadcast you cannot re-capture, the lossless rewrap path means conversion is safe: the common case changes the wrapper around the video without touching a single frame.

Tips

Getting a better result out of TS to MP4

Specific settings and thresholds, not general advice.

  • A conversion that finishes in seconds took the lossless path, which is the normal case for HDTV and DVR captures.
  • If a DVR splits a recording into several sequential TS files, convert each one and join them afterwards with the video merge tool.
  • CCTV exports sometimes use proprietary variants; a TS that no ordinary player opens may need the vendor player to export a standard file first.
  • Keep the original of anything evidentiary; convert a copy.
Limits

What TS to MP4 does not do

The honest boundary, so you do not lose time finding it yourself.

  • Encrypted broadcast streams will not decode.
  • When a stream carries several audio tracks, the default track is the one kept.
  • It cannot repair a capture with missing chunks; conversion preserves what was recorded.

FAQ

Common questions

Short answers for the questions people usually have before trying a utility like this.

Is this TS to MP4 converter free?

Yes. It runs in your browser with no signup, no watermark, and no limit on the file size.

Does the recording get uploaded?

No. Probing, rewrapping, and any re-encode run on your own device, which matters for CCTV and personal recordings.

How long does the conversion take?

Seconds for the common case, because the H.264 stream is copied into the MP4 rather than re-encoded. Old MPEG-2 captures take longer since those genuinely transcode.

Will the quality drop?

Not at all on the rewrap path; the video data is untouched, bit for bit. The re-encode fallback for older streams costs only slightly.

Why does my TS file show the wrong duration or refuse to seek?

Because transport streams carry no proper index; they were designed to be broadcast, not browsed. The MP4 container adds the index, which is why the converted file behaves normally.

Does this handle M2TS and MTS files from camcorders?

Yes; they are the same transport stream family with AVCHD flavouring, and they typically carry H.264, so they usually take the fast lossless path.
