How to use the TS to MP4 converter
- Choose your TS video or drop it on the box.
- Check the settings. "Same as original" resolution is fastest and lets fast mode copy compatible videos without re-encoding. Lower it to 720p for a smaller file.
- Click "Convert to MP4". A progress meter shows how far along it is.
- Download your MP4.
Why convert TS to MP4?
TS recordings from TV tuners, IPTV and stream downloads open in few editors and phones. MP4 makes them easy to edit, play and upload.
- TS: slightly larger than MP4 because of packet overhead.
- MP4: plays almost everywhere.
- MP4: good quality at small sizes with H.264.
H.264 TS files are copied into MP4 without re-encoding; MPEG-2 broadcasts are re-encoded.

Does converting TS to MP4 lose quality?
Often none. When the TS contains H.264 video, MP4 can hold it as it is, so fast mode copies the streams without re-encoding. Other codecs (including HEVC while "Play everywhere" is ticked) are re-encoded at "Balanced" quality, which looks the same as the original to most people.
How long does it take?
Seconds when fast mode applies, even for a full film. If the video must be re-encoded, expect a few minutes for a long HD video.
What is a TS file?
TS (transport stream) is the format of digital TV broadcasts and of HLS streaming segments. It is designed to survive transmission errors, which is why TV recorders and stream downloaders produce .ts files.
What is an MP4 file?
MP4 is a container that usually holds H.264 or H.265 video with AAC sound. It is built on Apple's QuickTime file structure and became an ISO standard in 2001. Because almost every phone, browser, TV and editing app can play it, MP4 is the safest choice when you need a video to just work.
