Can you first state the full details of your system, and then your Assets. Those are the first points that crashes occur.
In troubleshooting problems, here is the order:
5.) Bug (or built-in limitations)
What do you have to work with?
MacPro 2,1 3.0 Ghz 8 Core w/ 13 GB RAM - and using at least 3 or more HD formats + large images and large screencap quicktime movies
but I dont know if the system is the questions here because I am about to invest in new system and it will be top of the line and top of Cuda spec
with the system I have and with the maxed out system I am getting -- I am 99.9% sure --- vegas would choke with long mixed format timelines...
that why i was seeing if anyone has expereince in this regard...
What are the pixel x pixel dimensions of those "large still images?"
Are you mixing different Assets in the same Sequence?
>long mixed format timelines
I read all 3 of the forums (2 PPro and Elements) so don't know where I read this... but I have read a message in the past month or so from someone having problems trying to edit a timeline with "mixed" video
The advice was to do conversion(s) to make everything on the timeline the same
I don't know if CS5 has this kind of problem or not
CS5 seems to have fewer problems, than either previous versions of PrPro, or PrE, but much will depend on HOW "mixed" the Assets are.
Normal workflow would be to choose the prime source, create a Project/Sequence to match those files, and then convert the other Assets to match.
