I'm trying to export 70 minutes to/ 720x480 / QT file.
Using H264 takes about 15 hours...( fifteen?!) . And using MPEG-4 it takes 2 hours.
I understand it has something to do with resolutions. Any more ideas?
Do a video mixdown of your sequence, output a same as source quicktime as an intermediate, then run it through mpeg streamclip to an h264. If you system is any good, you should save your self several hours.
