ae can't render h.264 too well (or any codec that uses temporal compression, like hdv, mpeg-2, etc.).
you be best off to use a compression utility. i like this free utility mpeg streamclip but there are others. aslo, if you have fcp, then you should have compressor, which will work well, and if you have cs4, then you should have adobe media encoder, which will work too.
also, if you really want to let the web guys handle the compression, send them a lossless mov. that way the file only gets compressed once. right now it will get compressed once to h.264 and again for flv, so you will be losing a bit more quality.
Thanks for your reply,
yeah been using compressor, but not happy with the results. Washed out.
Same with exporting out of final cut.
And the work around people talk of does nothing for me.
But handy to know that AE's H264 encoder isn't up to it. Least its not me!
Hadn't thought of using MPGstreamclip for h264 encoding, I'll give it a go.
yeah lossless would be a better delivery for web guys, but its just a workflow issue as I'll need to send all the clips to them via yousendit. High quality H264 seemed to be the best compromise.
