Should you convert MP4 to TS?

Usually a quick, safe conversion. TS can carry H.264 or HEVC (H.265), which is what MP4 files normally contain, so the video can often be copied across without re-encoding: fast, and with no loss at all.

Check that TS is really needed: it plays in VLC and many TVs; phones, editors and upload forms often refuse it, while MP4 is opens everywhere.

MP4 is the video container that plays on everything, usually holding H.264 video and AAC audio; TS is the broadcast container, also used by camcorders (.mts) and web streaming. Use TS for streaming segments and broadcast equipment; convert recordings to MP4 to share them.

How to convert MP4 to TS

  1. 01

    Add your MP4

    Drop your MP4 video onto the box, or click to choose it. It is read from your disk and stays there.

  2. 02

    Check the settings

    The output is already set to TS. Change the quality if you want to; the defaults suit most files.

  3. 03

    Save the TS

    Press convert and save the TS. Several files come back together as a ZIP.

What changes when MP4 becomes TS

Often a straight copy

When the MP4 holds H.264 or HEVC (H.265) video, the stream is moved into the TS container untouched, so the conversion takes seconds even for long files. If the codec inside is something TS can’t hold, the picture is re-encoded instead and you’ll see a progress bar that takes longer.

Expect a larger file

TS generally takes more room than MP4. If the file has to fit an upload limit, check the size once it’s converted. MP4: 1080p phone video runs roughly 60–130 MB a minute. TS: About 5–15% larger than the same video in MP4.

This page is put together from our notes on each format, choosing only what is true of MP4 and TS, so every pairing states the same facts the same way. How these pages are made.

Why it doesn’t upload

Video files are big, and uploading one just to change its container can take longer than the conversion itself. Your browser can read and write these formats, so the file never has to leave your device.

How to check for yourself

Worth knowing

  • About the MP4. An MP4 that won’t play is rarely broken; it usually holds a newer codec such as HEVC or AV1 that the player doesn’t support.
  • About the TS. A downloaded stream often arrives as hundreds of small .ts pieces; each is a valid video, but you need to join them first.
  • MP4, MOV, MKV and WebM are handled by your browser’s own video engine, often with hardware help. AVI, WMV, FLV, MPG and the other older formats use the FFmpeg engine, a one-time 31 MB download, and are slower.

Questions

Does converting MP4 to TS lose quality?

Not when the video can be copied, which is the case for most MP4 files: the stream moves into TS untouched. If it has to be re-encoded, the default quality keeps the difference invisible.

Will a TS play on my phone?

TS has patchy support: VLC and many TVs; phones, editors and upload forms often refuse it. VLC plays TS and MTS files; many smart TVs play them from a USB stick.
