It embeds media, it does not process it
There is no video transcoding and no re-encoding. Transcoding was removed in 2.4.0 and the plugin bans exec-family calls outright, which is grep-verified in both halves. Upload what your members shot; MediaVerse will show it, not convert it.
The same reasoning covers documents: PDF, text, Markdown and CSV preview inline, while Word, Excel, PowerPoint and ODF get a download card. No server-side conversion, no LibreOffice on your box.
