Ask HN: How to use AI/ML to cut all dead time from table tennis video matches

Hi all,

I am a table tennis player and I like to record my matches for learning purposes. The problem is I always have to manually cut away the boring stuff (pick up balls, time outs, towel breaks,...). Are there any open source libraries I could use to do this with AI/ML? What is the best way to start? I am an experienced web programmer looking to build this as a hobby. I tried to Google but haven't found a solid library yet. Thanks for your recommendations!
