On the bad side, it takes something like 8-9x realtime, meaning for every hour of raw footage, it takes somewhere between 8-9 hours to process.
You do the math.
It's not like I can just start it and walk away either. The clips vary in length from 30 seconds to ten minutes. I can do other stuff during the longer render times, but most of the clips are shorter.
It's gonna be a long night.
