I outsource a lot of animation to another company, that mainly uses After FX and Maya, here is the thing, they don't have FCP 6.02, is there any way to get the codecs to install in a machine without FCP 6.02, they have 5.+

Might be best to convert the files they need to prores or animation codecs.

My After Effects CS3 accepts the mp4-files straight from the camera.
