When I set up the format from AVI to MPEG4, I can find the warning on the bottom.
Warning : Output file will be resized from 1920x1080 (1.00 PAR) to 176 x 120 (1.21 PAR) to meet format constraints.
Warning: Frame rate of output file will be adjusted from 30 to 15 fps to meet format constraints. Audio my not synchronize.
- what exact Ae version. (full numbers)
- what is your exact workflow? show screenshots of your menu selections, this probably something to do with wrong set of parameters of your output settings.
First, your level is too low. Make it the highest it can be.
Second, you really shouldn't render MP4's out of After Effects anyway, it can be a bit buggy - as you've seen - and it doesn't even offer multipass encoding. It's better to render an intermediate file (like QuickTime with the PNG codec) and then use the Adobe Media Encoder to make your deliverable. That's what AME is for. You can even set up watch folders so the encoding happens automatically.
Third, you should really update AE. You are missing lots of bug fixes! CS6 should be on version 11.0.4, but you're on 11.0.0.
I didn't need to render MP4's.
Now message(warning) pops up before hit the settings..
I changed using Premiere Pro then After Effects..
Premiere works okay..
Thanks alot for helping me !!!
(I was so desperate)
