Benefit of Self Compile

[zerodefect]

Considering that video encoding is such an intensive process is there any benefit to compiling any open source components that ffmpegX uses or are they pretty well optimized already?

I don't think it would change anything, as most of the time-critical operations are now handled in assembler code in many engines. Also on Intel the architecture is pretty much the same on all Macs apart from the new Xeons.
