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.

About Ogg Video
Ogg Video (OGV) is the open Ogg container from the Xiph.Org Foundation holding Theora video, usually with Vorbis audio.
Open-source projects and Wikimedia Commons, which accepts video only in free formats.
Theora compresses less efficiently than modern codecs, and Apple devices do not play OGV natively.
Why convert video to OGV? For websites that standardise on open formats: Firefox and Chrome play it without patented codecs.
