I'm new to Creative Cow and relatively new to AE. I'm using AE CS5 and am doing a video library project. The issue I have is some renders are experiencing a jitter/stutter when rendered. Only 7 out of about 300 videos (all with the same original footage (ie. frame rate etc) suffer the problem, the rest are fine.
I'm renderingin a Macbook Pro in After Effects to mp4 with the built in H.264 encoder set to VBR1 and 5-8mb min to max (that seemed to produce the desired results in the test renders)
