Alright, I was able to find that information finally. It's variable obviosuly with a max 30 and target 25
I think I may have figured out the real issue though. The project I am making has 3 seperate videos/timelines (three of each) and I think encore is just using the first video to set the transcode settings because after doing a little looking, the estimated file size of just one of the videos is like 19GB. So it isn't taking into account that there are three files before it starts transcoding, and obviously when it's done the whole project is too big for the disk.
Any ideas?
