I need to get my file from AE on a MAC to a true AVI. Does quicktime pro really convert the .mov to a true AVI that will play without quicktime on a PC via the export AVI function?

I use premier instead of final cut as well, is compressor a good option (and can it be purchased seperately?) for encoding MOVs to AVIs (not .wmv)

Thanks for the help-
Jessica

If I'm wrong, someone will jump on this for sure, so stay tuned.

Yes, AE will create AVI files on a Mac, but you will definitely want to make them Lossless (if that option is available) or Uncompressed.... and let the next person in line convert them to AVIs in their codec of choice.

The reason: a shortcoming in Quicktime. QT doesn't have the full panoply of codecs for AVI files. It has really high quality... and garbage. No in-between.

Useful info again David. I didn't realize that there were issues with AVIs and QT Pro. I just made some AVIs a few days ago for a client, but luckily I ran them through Compressor.

[Andrew Saliga] "I didn't realize that there were issues with AVIs and QT Pro."

There may be flaws in QT, but I don't think you can count AVI creation among them. The lack of useful codecs in QT is more likely a case of Apple and Microsoft not playing nice together.

To build on Dave's point, both Quicktime and AVI are "container" or "wrapper" formats. Container formats describe how to store and read tracks in a file, but not how to actually interpret the streams. That's where codecs (codec stands for compressor/decompressor) come in -- they actually describe the video, audio, timecode, subtitles, etc.

You could store just about any kind of video in an AVI -- Cinepak, DV, uncompressed, h.264, etc., but the codec must be installed on the system for playback. Here's a list of codecs pre-installed on PCs:

Thanks everyone for your help! It seems their display program was able to read the direct export as avi from AE.
