DVD Ripper 2 pass encoding really really slow

[ryanmc]

I have been experimenting with some different options in DVD ripper, and I tried 2 pass encoding. After a couple minutes the estimated time was over 8 hours. This was way too long, so I switched it to 1 pass encoding and it completed with in 10 minutes.

So why the discrepancy? I thought 2 pass encoding would take 2x the time, not 200x the time.

BTW I am using Windows 7
DVDfab 8.1.7.8
mp4 iPad3.h.264 1080p encoding at 1600 kpbs

Any idea about this? Do you need more information?

Yeah seems very slow at the moment it seems to constantly drop fps

ryamc, it appears from your log that you are attempting 1080P from a standard definition DVD. Just use the iPad.h264 profile and set the bit rate high enough so that bit/pixel is 0.2 or higher and use one pass. Trying to make the frame resolution larger than the original is really a waste of time IMHO. The iPad will fill out the display and I think you'll be pleased with the result.
