Watching video doesn't need much power at all. Video editing however is a different matter and you'd also need a decent GPU so that leaves the Mac Mini out.

One of the last things I did before I retired (in 2013) was editing a doc that combined archive and original video.
I did the rough edits at home on a Mac Mini 2010 using Final Cut Express 4 - one of the reasons I upgraded my 2008 'lunchbox' version in fact.
Perfectly capable it was too
Final Cut specs
Whether it would cope with modern requirements is a different kettle of worms though....
