buddyweiser 105 Posted February 4, 2014 Share Posted February 4, 2014 I'm wondering if anyone has this problem or can offer any advice. I'm using DVDFab to encode foreign-only subtitles onto MP4 video files for movies such as The Wolverine, Elysium, and Captain Phillips. Here is the problem: DVDFab supports CUDA GPU to encode/decode video, however when I select the option and start a task, the "Encoding fps" drops to 8, then less than 1fps. On Software encoding, it never goes over 30fps and takes sometimes 5 hours per movie. Could this be an issue with my GPU? I have searched multiple forums and cannot find a solution to this issue so I thought I would bring it here where my questions are pretty much always answered Here is a shot of the settings screen.

buddyweiser 105 Posted February 9, 2014 Author Share Posted February 9, 2014 My GPU is an ASUS GTX650 2GB 128-BIT (GTX650-E-2GD5) and my CPU is a Intel Pentium G3220 3.0Ghz Link to comment Share on other sites More sharing options...
shaefurr 1337 Posted February 10, 2014 Share Posted February 10, 2014 Try ripping to another format like mkv, I read the mp4 profile in dvdfab 9 has a bug, if it doesn't improve I can try dvdfab 8. You should definitely not be getting such low encode fps on that system Sent from my XT907 using Tapatalk Link to comment Share on other sites More sharing options...
buddyweiser 105 Posted February 10, 2014 Author Share Posted February 10, 2014 Well, I kind of fixed this issue. I don't know if the Common Settings were messed up, but I did a fresh install and now am getting over 60fps on CUDA encoding. However, DVDFab won't let me choose 2-pass encoding, and instead I have to use "CRF". What exactly is the difference between these two, I've always heard that 2-pass resulted in higher quality.
