I am running the melt command on a 4-core system with no other software running 
(except system services), and I am only seeing about 30% CPU usage (134% of the 
theoretical 400% on the box). ffmpeg and other commands are fully utilizing the 
cores (380-410%), so the power is definitely available. All the files are being 
read from tempfs (RAM-based disk), so while there is definitely some latency 
for file access it should not be significant compared to the same media stored 
on physical media.

Is melt able to utilize multiple processors? If so, why is it only using about 
1.5 CPUs of the available 4? Are there settings I can adjust to better utilize 
the host machine?
