I have tried a couple of the h.264 presets ... HDTV 720p seems to work fine however its the Vimeo HD preset which seems to give me problems.

The only thing I can see which is different between the two is obviously the target and maximum bitrate... and also the profile setting. The vimeo HD profile setting is 3.1 and the HDTV 720p is 3.2 Im not too sure if that would affect it. I dont have a lot of knowledge on profiles. That and keyframe distances.

Ok so you say I should alter the good preset until it gives stuttery results. Not too sure what I should alter first.

At the momemnt I am exporting as Quicktime animation and then converting to h.264 in mpeg streamclip ...which seems to give good results.

I am running a imac I7 with 8GB Ram
