Should you convert M4V to TS?

Usually a quick, safe conversion. TS can carry H.264 or HEVC (H.265), which is what M4V 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 M4V is mainly an Apple format.

M4V is an MP4 video with Apple’s extension; 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.

Save the TS

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

What changes when M4V becomes TS

Often a straight copy

When the M4V 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 M4V. If the file has to fit an upload limit, check the size once it’s converted. M4V: The same as the equivalent MP4. TS: About 5–15% larger than the same video in MP4.

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 M4V. Films bought from the iTunes Store are copy-protected and can’t be converted by any tool; your own M4V exports convert in seconds.
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 M4V to TS lose quality?

Not when the video can be copied, which is the case for most M4V 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.
