Multiple format projects and crashing

Hey all,

After much futzing around with a lot of crashes during attempts to render, I found that I could prevent crashing by following a few "rules" to work with Vegas 8.0 and 8.1. Perhaps if we build a rule list, it could help the many uses plagued with these issues.
Here is my basic list so far:
1. Avoid using multiple disparate video formats within the same project (i.e. MP4 files from one camera and MTS from another, etc.). Create HDV intermediates and bring those into the project with the most native Sony formats.
2. Avoid JPEG images (most of us know this). A work around is to pre-render the segments with JPEG's first.
3. Render projects to HDV 1080-60i AVI files using the default HDV Cineform Codec (BIG files....)
4. Use the file from step 3 to create the final versions you want for distribution (Blu-ray, MP4, MPEG's, etc.).

By doing this I finally had a project work without crashing during the render process for the first time in months...

Looking for Vegas 9 to fix the memory issues and clean up some of these issues.

Any other rules of the road others use?

Mike

I have absolutely NO issues with HDV or jpeg's at all anymore. Two hour time lines... 800 plus events with effects/transitions.... In fact the only issues I have with Vegas now is rendering to AVC. I do get a fair bit of crashing. But then rendering a avc time line over to mpeg2 clears that up. I've even mixed jpeg's avc, and HDV on the same time line with no issues (as long as I render over to mpeg2).

There are however a couple of different jpeg varieties and Vegas is a allergic to one of them.

Probably not the cause of any crashes but in a similar vein to reducing the load on Vegas during render and playback:

Get all audio the same sample rate. For example if you have music ripped from a CD use Vegas to convert it to a 16/48KHz wave file first. Make certain Audio Resample quality is set to Best while doing this.

Last night I was editing XDCAM 720p50 with client music from a CD. Converting the client's music to 48KHz was enough to avoid occasional dropped frames during playaback.

All of your advice is solid and inline with what I've seen happen on complex projects.
