You can also set size requirements too which is pretty interesting because if you don't set size parameters you could end up grabbing an upgraded file that's like 100 gigs or something because it's like an uncompressed audio woth multiple language files version of a video but Setting a limit for the types of files you want is extremely helpful. It takes a little bit to dial in based on your preferences, but once you have it dialed in, it's pretty slick.

I imagine it’s a lot of trial and error in the begining. Like you set a benchmark size for 1 hour of video and then go from there
