I've been doing a lot of projects recently working between AE CS4 and FCP.
All the work I've been doing has been animation based and all projects have been HD. I've been rendering out clips of up to a minute from AE as .mov with H.264 codec and then putting them in FCP to edit together.
The problem that I'm having is that quite often FCP runs slowly once there are a lot of mov files in the sequence. It also crashes when there is a long (50 seconds, so not really that long!) .mov clip in the sequence. I was just wondering if there is a better way for me to be rendering these clips out for use in FCP. Obviously they need to stay at a very high quality.
Any help would be much appreciated,
H.264 is a delivery codec: it's not really ideal for editing purposes, and the
decoding of it may be what's clogging up your system. Try using the Apple ProRes HQ codec - it's very high quality, and designed specifically for HD editing.
As Andrew said, simply use different CoDecs and don't get miserly on file sizes. Simply buy another harddisk, if you run out. H.264 is very processor intensive and even the most beefy MacPro with FCP3 can only decode so many such files in realtime. For ProRes, Todd provides additional guidelines on his blog, but of course other CoDecs shoulkd work as well.
Thanks very much guys. Great advise as always!
