The current code doesn't appear very optimized. Running on CPU-only it only uses four threads for example, nowhere close to saturating all my cores.
As a result it's dog slow on CPU only, like 3-4 minutes to produce a 3 second clip, and still significantly less than real-time on my 5090 using only 30% of the GPU.
