Audio out of sync with video issues with AE7

I have a problem I was hoping I could get help with. I have Adobe Prodution Studio Professional, and use the Canon XL H1. With the camera, I create .m2t files that when I import them directly into Adobe Premier 2, the audio and video are in sync. When I import the same file into AE7, the audio is out of sync with the video. What am I doing wrong?

Convert the m2t file to another format before importing into AE. If I'm right, m2t is an interframe-compressed codec like MPEG-2, and AE (a compositor, not an editor) doesn't like those.

Thanks for the reply. Yes, when I convert it to an avi file, everything works fine. Seems too bad that I have to convert it before using it in AE 7.
What would you suggest as the best way to convert? Can you suggest a particular piece of software? And when you say "Try Animation codec", can you give me more information on that?

If Quicktime Player opens the m2t file, you can use File>export there to convert "movie to Quicktime movie". Choose the Animation codec under "options>settings". It's a high-quality lossless codec used when transferring files between apps.
If you're short on space, use the Photo-JPEG codec. They're both Quicktime codecs.
Or you should be able to use Premiere to export to a different codec, no?
Or you could import an AVI file into AE-- that should work.

Just use no interframe-compressed MPEG-based files such as m2t or HDV.

Hey, no problem. :)
M2t import is probably low on their list, and that's understandable. High-compression sources aren't desired, since they're low-quality and their main advantage (speedy playback and low data rate) isn't needed, since AE has to render everything anyway.
That's the trade-off with AE: A lot of compositing and effects power means that everything has to be rendered.
HDV is an acquisition codec. It's not good enough for compositing.
By the way, see how far you get (compositing) with the average NLE before you have to render. :)
