I have SVP 11 I am trying to create and render projects (none bigger that 5mins). They have an intro, an outro and range from 2 mins to 4 mins. Some have rendered fine. Others have rendered and then the file has nothing on it when played. Others still have just stayed at a certain %age and not budged and others have crashed SVP. If I render in anyhting other than .mov SVP crashes too. CPU is at max agreed when rendering. Trying to find a long term solution (without having to change laptop or add memory to it - Settings maybe or file type or ??. Any thoughts greatly appreciated!!
You might want to download the trial of Vegas Pro 13.0 and see if it fixes your problem. To be honest, I never used Vegas Pro 11.0 in production because it was too buggy, specifically with rendering. I used Vegas Pro 10.0 until 12.0 came out. My suggestion is to stop using 11 and move on to something more stable like 12 or 13 (although I've had problems with 13 and moved back to 12 for some projects). Vegas Pro 10.0 and 12.0 seem to be the most stable recent versions.
