I have 2 disks from an episode release, one disk has 2 shows, another 3 shows, all shows are approx 50 minutes, the 2 show disk and 3 show disk
compressed with shrink in about the same time?
AFAIK, DVD Shrink works not by re-encoding frames but by raising the quant of the source (basically taking stuff out). If the source quality is high enough and DVD Shrink determines it can chop a lot without doing much harm to the final quant (within its boundaries) then it will proceed in rapid time.
An encoder on the other hand takes the source material and encodes from scratch on a frame by frame basis. This would certainly resulkt in longer encoding.
Given that both disks had the same size of files to be compressed, but one disk had 50% more video(time), then is it possible that shrink could do a say 70% compression on both in the same time?
I am ripping both disks to my hard drive to verify size, and will reshrink to verify compression and time?
Depend on the quant. I've done shrinks of just a few % that took an hour (they started at high quant and the prog needed to work to figure out where it could shrink) and other superbits of equal or longer time which breezed through. The larger the video, the easier it can be shrunk!
Well I started one disk with 2 episodes, compression was ~77%, it took longer than the 3 episode at ~72% on a slower computer. Makes sense, the 3 episode was already compressed a lot more. Sort of?
