Go to interpret footage and fix the problem. Select the footage in the Project Panel then go to File>Interpret Footage>Main or just right click and follow the link. AE Basics.
Sound in AE is good - it's not 50% slow as video (today I test this footage in Premiere - same issue).
So if I Interpret footage as 25 fps - sound will speedup 2x.
50% of my video! So Interpret footage - not an option!
And my project contents over 200 clips! So pre-comps (even with 50% of source video) - will be pain in ...!
I had to transcode all my footage to ProRes.. not using AME, because of same issue..
Do yourself a favor:
- Find the original footage.
- Transcode it into a Quicktime Movie in the Photo JPEG Codec.
- Use it in AE.
If your problems continue, write back.
I already transcode all footage to ProRes and it's work perfectly.
But it's time-consuming, free-space-on-hdd-consuming and definitely not workflow I expect from Adobe software!
If you're worried about using up your storage, get more storage. It's cheap.
And FYI, H.264 footage isn't the best choice for use in AE. It can cause too many problems.
If you're not happy with AE, may I direct you to Blackmagic's FREE Fusion Lite, a node-based compositing application?
