I want to be able to transcode Canon 5D mark II footage into codec Final Cut Express can handle without constant rendering or distorted aspect ratio. Source is 1920 x 1080 h.264 Using Streamclip, I transcoding to 1280 x 720 Apple Prores not knowing that Final Cut Express does not support any codec except for AIC. Not even DVCPRO seems to work. To be precise, FCE requires you to transcode your footage into AIC 720 x 480, 30fps. Or it will start killing kittens. Also note: apparently, Intel doesn't support the AIC encoder?!?! Streamcip has trouble transcoding 1920 x 1080 into 720 x 480 without distorting your image. So it looks like you can crop -100 from the bottom and top of the image to hack a non-distorted 720 x 480 image. So this: If there is a better solution out there, I would love to know about it.
