AE CS3 buggy & crashing – on import and layers disappearing, etc
Message:
I have been working on an 8 core Xeon for 3 months with no problems. Suddenly, yesterday, AE CS3 started:-freezing on select imports (2 files would be imported but the 3rd would cause a freeze)- have to force quit
– layers in comps and timeline intermittently disappears – have to quit and restart
– freezing on replace footage
– footage intermittently is “missing” (when nothing has been moved).
– AE changed the set frame rate on select moviesI’m going nuts trying to figure this out – if anyone has any systematic way to troubleshoot this, I’d be very grateful. I am in the middle of a complex project and, well, you know…

this is from dave laronde, but it is a common problem if you have any of these file types…
Dave’s Stock Answer #1:
If the footage you imported into AE is any kind of the following — Native HDV, MPEG1, MPEG2, mp4, m2t, H.261 or H.264 — you need to convert it to a different codec.
These kinds of footage use temporal, or interframe compression. They have keyframes at regular intervals, containing complete frame information. However, the frames in between do NOT have complete information. Interframe codecs toss out duplicated information.
In order to maintain peak rendering efficiency, AE needs complete information for each and every frame. But because these kinds of footage contain only partial information, AE freaks out, resulting in a wide variety of problems.
now there could be other problems… since this suddenly occurred, what has changed since this wasn’t happening? since many of the issues seem to involve footage, i’m wondering if quicktime had been recently updated on your machine… quicktime updates have been known to cause issues with video application, including apple’s own pro apps, so that may be the cause.
if you are on a mac and think it may be quicktime, you can download an earlier version of quicktime from apple (i have 7.5 running with osx 10.5.4 nicely) and a shareware called pacifist to effectively revert back to an earlier version of qt. you may also be able to use time machine to go back and ‘undo’ the quicktime update if you have time machine enabled.
if you are on a pc, you may be able to use the add/remove software to revert back to an earlier qt version…

Thank you.
I did a clean uninstall from the disc image, and fresh reinstall, and also got rid of flip4mac and blackmagic codecs – putting these fun facts together from various advice sources. anyway, all is back to normal. i had added no software no updates, nothing that I could see to have caused this meltdown. BUT it’s great that it’s not only fixed, but running better than before.
