So I had recently uninstalled After Effects just a little while ago because of inactivity but today I re downloaded it (CC 2015) and I tried to import a hour long clip but it gave me the following error above. I don't know what this means but I researched except the answers that came up on the forum weren't accurate or clear. I have a Mac book Pro and was wondering if anyone else was having the same problem and or solved this problem before..Please help it would be much appreciated!
Of special interest would be things like exact version of AE you're running (CC first downloads the original version and sometimes doesn't tell you about updates, so exact version number of AE, please), what format and codec the footage is in, your OS, and your hardware.
I contacted support and they took a look at my problem. I even shared my screen with them but it appears to be a problem with QT. I have no idea how to fix it because the chat session with the adobe support person ended abruptly and without a clear answer or solution. All he said was that I may need to Re install my OS which I really do not want to do.
