Playback choking on rendered file

I just finished editing a 10 minute clip. Playback with the orginal unrendered clips and FULL FX works just fine. Let me repeat that: Playback BEFORE RENDER WITH FULL FX WORKS FINE.

So, I rendered the clip to a single AVI file, and it came in at ~500 Meg. I then bring this into a new project and playback totally chokes. It is hanging 10 and 15 seconds at a time, so playback is totally useless. Usually, you expect this with the project BEFORE it is rendered, not after.

Everything I've read deals with real time playback during the actual edit and full fx applied, which, again, works fine.

Why then, is the rendered file totally choking in playback? I mean, it does fine reading individual clips and assembling them on the fly, but can't handle a finished rendered file. Something is not right here.

What type of AVI file did you render it as?

AVIs can use any of a number of codecs. The DV codec is ideal if the video is standard definition and you plan to edit the AVI in Vegas. It's not a good choice if you're working with hi-def video.

About the worst thing you can do is output an uncompressed AVI and then try to edit with that. You end up with a huge, bulky file that offers no better quality than a DV-AVI because you started with already compressed video.

I've had the problem with both Divx and WMV renders. I'm using uncompressed raw video for the first render, so things are compressed quite a bit.

It's choking on both, but can play the raw video in a project without a hiccup. We're talking 20-30 gigs of raw video in the project that plays just fine and about 8 Gig in the render, which it cannot handle.

Something is not right here.

Uncompressed AVI video is extremely hard to edit. It's even hard to play! As I said above, AVI video with the DV codec is the perfect balance of quality and compression and the ideal format for editing in a program like Premiere Elements.
