I'm making a mech-like thing.
The legs of the mech have to lift up and over each other (think of the AT-ATs from Star Wars).
I can't do that in 4 frames; its too complex. I have spent a LOT of time on this model, I'd HATE to drop it now.
Right now I have it set to 320 frames, though I can reduce that number to maybe 32 if needed. Maybe even 16. But not 4.
