Should you convert WEBM to TS?

Yes, when a device or app needs TS. TS can’t carry the VP8, VP9 or AV1 video found in WEBM files, so the picture is re-encoded as H.264, HEVC (H.265) or MPEG-2, which takes about as long as the clip on a recent laptop.

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

WEBM is the web’s open video format, holding VP8, VP9 or AV1 video with Opus or Vorbis 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 WEBM to TS

  1. 01

    Add your WEBM

    Drop your WEBM 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 WEBM becomes TS

Re-encoded, at a quality you choose

Because the video has to be compressed again, a little detail is lost. The default quality keeps the difference invisible; choose High for footage you’ll edit further.

Expect a larger file

TS generally takes more room than WEBM. If the file has to fit an upload limit, check the size once it’s converted. WEBM: Usually a little smaller than MP4 at the same quality. 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 WEBM 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 WEBM. Browser screen recorders save WEBM, and the recording then fails to upload or attach almost everywhere else.
  • 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 WEBM to TS lose quality?

The video is re-encoded, so a little detail is lost, but the default quality is set high enough that it doesn’t show.

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.
