+Introduced some restrictions on the goroutines (from copilot). I need to brush up on the logic with these, but the purpose is to keep the program for crashing with the new batch feature. Currently it doesn't seem to restrict performance: generating video took 0 hours 1 minutes 34 seconds with this new 10 core restriction.
