After Effects render out of sync

Zarxrax · Post by **Zarxrax** » Fri Dec 28, 2007 7:07 pm

So, I go about working in After Effects, checking everything in RAM previews and all, everything looks great. Then I go and export to a Lagarith file, and then compress that to whatever. My output plays back out of sync. Just a few frames off, but enough to completely kill the mood. I can take the Lagarith back into AE, or premiere, or wherever, and it previews perfectly fine.

Whats going on here?

That happened to me and some friends even with huffyuv, not only lagarith. Exporting in uncompressed seemed to work, at least for us. Oh, and also: I don't trust AE RAM preview that much. It keeps the audio playback 4 or 5 frames off sync with the video when I RAM preview, but when I export is actually all fine and perfect. I prefer to watch the audio form and look where the level edges are. But this problem might be my weak PC more than an AE problem. More IT, if exporting uncompressed doesn't work, then I have no clue.

Well, I just tried exporting uncompressed, and no difference.
HOWEVER, I also tried exporting as h.264, just for the heck of it. And I'll be damned, it's in sync! Theres something really screwy going on, keeping AE from exporting my avi files in sync

That's actually weird! If I try to export compressed straight from AE, it will make some render mistakes. Like forgetting nested compositions or not exporting layers that are actually there with the visibility turned on and the opacity @ 100%.
I actually understand this program less and less every day. o.O
In the CS3 I did Composition > Make movie and AE tried to directly render an avi without letting me change the settings. I had to do Composition > Add to render queue. That happened me once, tho, after that, it always worked as in the previous version (Ctrl+M adds to render queue).
Maybe after effects dislikes big projects or something like that...? :\

That might actually be true. CS3 can't find the audio tracks when opening 7.0.1 projects, and some old projects can't even be imported at all. Gives strange errors and such. Luckily I had huffy of the old projects so I lost just the layers, but it's sad anyway... but I had to use after effects cs3, as I couldn't obviously import premiere pro cs3 projects in after effects 7.0.
Bah, I don't care. Even if it gives random errors and such, it still works. I can't downgrade to 7.0 now as I'll loose my projects... aaaah, I do care: I hate it!

I don't recall ever having this problem before upgrading to CS3 either...

Perhaps if you try to give feedback directly to adobe, they might release a patch, as they did in 7.0... they fixed some bugs with the release 7.0.1.
