Why is quicktim

Yes, H264 is a part of MPEG-4, called MPEG-4 layer 10. You can encode to this with QT Pro ver. 7 (it demand ver. 7 to encode/decode), and an alternative could be MPEG-4 standard, which is included in QT 6. One of the best encoder is Sorenson Squeeze, which supply some further features, and can be highly recommended if You need high quality/encoding workflow.
