I haven't looked it to just yet. But, I looked at the code in the
videocrop, I don't think it could be much faster, with the simple format
the way it is, maybe threading it, but that adds complications to
everything else that could slow things down.

Also, typo. I meant to say that I will look a lot into speeding it up. =P
