I previously used Vegas 8 and could use well beyond 4 video rendering threads by simply right click on an empty thread and select ‘insert video track’.
In Vegas 9, in the preference menu than in the video tab it shows that the maximum number of rendering threads is 4. I increased to maximum usage of RAM (1024MB) and even than its maximum is 4 threads.
Is there any way to increase the threads in Vegas 9?
