Even a QT will play bad if you don't apply a compressor to it. You need to add a CODEC and not render an UNCOMPRESSED file. There are very few computers that can handle an uncompressed file playing back in any player- DIVX is compressed AVI and QT could be either way depending on your settings.

DIVX as Sunny mentioned is good

For QT: you can run animation or preferably Sorenson (go to Sorenson.com and see if there are newer versions you can download for free)

For AVI/WMV: you can run the MPEG4 V3 codecs that will play in media player 6.4 and above

The codecs are mostly determined by what players are installed in you system.

If you have any kind of editing system- Find out what codecs it uses and render with them- this way its all compatible.

Testing can be done in any compressed format you want- but You want your final renders to be uncompressed until you compile it to create you final Output. This was mentioned in another tread and was great advice. If you render an compressed file and then compile it in an edit system then output another compressed file- you will loose quality because you create a compression of a compression. Ive even seen bad color hellation and cuttoff frames and wired pixelation from this situation.

I use a great CODEC that is high quality and will playback on most systems(with the codec- which I installed). Go to Avid.com and look for the meridien CODEC and install. Then render a QT with the MERIDIEN Compressed compressor and select 2:1 NTSC. (Note: I think the frame needs to be 720x486 D1 non-square pixels- which you can set in the render options)- I'm trying to find out from Autodesk what system they use (if any) to compile these animations- if they use an avid they it should be OK to deliver this way even though its not 640x480- I HAVEN'T HEARD BACK FROM MY EMAIL A FEW DAYS AGO SO I'M STILL WAITING TO SEE.
