Thank you very much for the swift response, I guess from what you are saying that if I want the quality I need to invest the time!
Apologies, yes WMV is what I meant.
Thank you for the heads up in the aspect ratio, much appreciated. I changed the settings to 6.7 Mbps HD 1080-25p Video and it seemed to go a little quicker. It now averages out at about 1 frame per second rendering time, so each file takes 25 x real time to render. this still was using only about 25% of CPU and mem so I figured out a way to work more effectively. I open 3 separate instances of Sony Vegas and set them all rendering together. It takes the same amount of time per file but at least I am rendering 3 files together!! It also allows me to open a 4th one to work in while the other are rendering.
One last thing, I don’t suppose you know if Vegas works well / better on XP / Vista 64 bit as my CPU still has some more to give but with 4 Vegas sessions open it is the memory which is the limiting factor (limited to 3.5GB by 32bit) so I figure if I changed to 64 bit I could get a 5th session open before I get to 95-100% of CPU. What are your thoughts, again thank you so much for your help, now I am re-rendering everything in the correct aspect ratio!!!!
