First time actually came to rendering in the new Vegas Pro 18. Rendering using 32bit full range there is an issue. The firs time I went to render it did render, but the preview screen was flashing between black and the video image, this was also rendered into the video itself.
So, went to re-render and it just wouldn't and came up with an error message. I've uploaded a video to show this. Setting ram preview to zero had no effect on this, same issue. I always 32bit full range as I always get odd banding artifacts using 8 bit. Full range always gives me the best quality.
The only way to fix this was to turn off GPU acceleration. (my spec are in my sig)
