IF clips takes too much ressources...
If the clips are too resource intensive because people are clipping garbage... Just remove it and replace it with uploadable video for affiliate and partner.
Limit it to streamed content and moderate it. You will have sooooo much less data to deal with and every streamer worth their salt can just add a replay buffer action to their bot, then upload later.
Or just use technology and timestamp the VOD that is already available at the end of each stream anyway. You could scrub to where you see the most timestamp and have the user go at it. It cost nothing. make it like a facebook live replay where you see a graph on the scrubber to make it so you go see where the action was.
Facebook live like replay scrubber: Add a user interaction graph to the scrubber when replaying a VOD. You could easily go back to those moment where the chat exploded.
