I think I found the answer with the error/ H.264 issue people. If you do you what the comments say for each setting (e.g. for H.264 – 720×480 on the stretch settings) and then click the aspect ratio checkbox off it should work. Well, I am rendering it now and it seems to be working – No more ‘AEGP Plugin Media IO Plugin: There is a mismatch between Output Module settings and Transcode Setting’ errors occurring.
