+ File runtime
+ Container and track formats
+-- Resolution
+ File name
+-- Presence of year in filename could indicate movie
+-- Split file (.cd1/2)
+-- Episode-based regexes, adjacent files with similar file name structure
+-- Presence of music video artist in music database
+ Tokenized path as a feature vector
+ Scraper results - catch-22 dilemma, but scraper results do verify our decision

These are great!

I'm semi unsure on what you mean by "Presence of music video artist in music database" and "tokenized path as feature vector" though.

The rest I think most are possible, atleast the file name ones, to get from the current data.
