About MPEG Transport Stream (TS)
An MPEG transport stream (TS, MTS, M2TS) is the container used for digital TV broadcasting and Blu-ray. It is built from small fixed-size packets that tolerate transmission errors.
TV recordings, AVCHD camcorder files (.mts), Blu-ray discs (.m2ts) and HLS streaming segments.
The packet structure adds overhead, and many editors and phones do not open TS files directly.

Why won't my media player open the .ts file I recorded? A transport stream is written for broadcast, so many players expect a renamed or converted container before they accept it.
About WebM
WebM is an open, royalty-free video format developed by Google and based on the Matroska container. It holds VP8, VP9 or AV1 video with Vorbis or Opus audio.
It is made for the web: all major browsers play it in the HTML video element, and it is common for screen recordings and short clips.
WebM allows only its own small set of codecs, so H.264 video or AAC audio has to be re-encoded to fit.
Why convert video to WebM for a website? Browsers play it without plugins, and VP9 or AV1 compresses smaller than H.264 at the same quality, so pages load faster.
What changes when you convert TS to WebM
