I am somewhat of an amateur at Adobe After Effects. I have made a movie that I would like to be turned into the AVI format. I went to Composition > Make Movie, and waited the 5 hours that it took to render. Once done, the movie lagged, went faster then normal at some parts, and had no sound!! Please help!!

picture of a speaker needs to be enabled in composition.
output module audio output needs to be checkmarked and you probably exported an uncompressed movie which is more info than your hard drive can playback smoothly. try a DV video compression and see if that helps.

There's a problem that's growing among AE users, one that rarely existed in years past: using the wrong type of footage. Read on....
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.
