Speed is not min(filter1,filter2)

CPU is a quad. Code:

Mode 2 MT the caused random access on your AviSource, unless you are using a keyframe only format .AVI file like Huffyuv, DV or uncompressed, the seek overhead is extremely high. You can use ChangeFPS (clip1, clip2, bool "linear") to linearis you access pattern. Something like :- Code:

The problem is that mcbob and mctemporaldenoise are not running in parallel. Can I make mcbob start on the next frame before mctemporaldenoise is finished with the previous one? Would really like a speedup here as the video is over half a million frames...

if you're going to run multiple scripts simultaneously then it would make more sense to split them length-wise with Trim(), rather than do some weird selectEvery() style which would probably not see much if any speed up if there was a temporal filter used.
