Main Movie goes over the 25gb target?
I'm using BDrebuilder to simply compress my movies to main movie (25gb) and have noticed some movies go over this target. I'm using ffdshow as frame server and using crf for quality on the high quality (default) setting. Does anybody have any previous experience in regards to this problem and how to rectify the problem. Thankyou

CRF uses an alogorithm to attempt to predict output size, it is pretty accurate, but can sometimes be wrong. If it oversizes, look at the predicted value, and set a fixed CRF that is slightly larger.

Thankyou for getting back to me. The movie in question was very grainy and them type of movies rarely encode well and can give huge file sizes. I did however try two pass and that got me a file around 21.5gb which was perfect as I don't like maximising the space on the Blu-ray Disc. In regards to the CRF can you manually set that? I'm just using the default high quality atm, could you tell me the crf for high quality. I assume its around the 21/22 mark.
