So my friends and I are making a short film for school and I'm a newbie when it comes to AE but I tried it anyways.
I got all the clips together which turned out to be 9 minutes and 20 seconds long and then I rendered. I checked the audio switch in the output module and I thought I'd just be fine there. But then the video and audio was all off-sync and lag-tastic.
So I tried changing file formats and I don't know which one to use... Anyone know which one? I'll provide as much information as I possibly can.
Thanks in advance!
What is the delivery codec and medium for your school? DVD? Web? Computer file?
If your audio isn't synced in the timeline it won't be synced when it is rendered.
If it is synched, are you doing this in HD and your computer doesn't have an HD accelerated video card? You can still render, but you won't be able to play.
Render out a file at 640x360 resolution and see if it plays appropriately. If so your computer is too slow to play hd content. If not, then you have problems you need to fix in your comp. Fix those. Then contact your teachers to figure out what delivery mechanism they want. Then ask us how to conform your footage to that if you can't figure it out.
