transcode encoding speed...


I've been trying out dvd::rip and xdvdshrink on my computer. Both of those programs seem to be insanely slow when it comes to encoding video. I used dvd::rip to rip the title from the DVD and that is decently quick, but even from the hard drive it takes forever (14 hours) to encode the ripped vob files into a single avi file. Even xdvdshrink takes as long to shrink the vob files. In dvd::rip I even set the nice process to 0, didn't seem to change anything. Only 35% on average of my processing power seems to be used.

the win32 version of DVD Shrink under wine only takes about 45min to complete this same task. Is there anyway to speed up this process?

Since you have DVDShrink working, you can use that. If you want an open source application, try k9copy. It uses a fast requantizer instead of decoding and re-encoding, which is the way DVDShrink works.

Even K9copy says it would take over 21 hours to complete the backup.

Are you sure you're reading that right? 21:00 is 21 minutes, zero seconds. I've run k9copy, and it typically takes about a half hour.

Update: From your snapshot, you selected MPEG4 re-encode, not the backup in k9copy. That will take a while.

It says 21:26:64. I'm assuming that means 21 hours 26 minutes and 64 seconds

Believe I solved the problem. When I set up my secondary partition to mount under /home I used the option sync in fstab. I changed that option to async and remounted. Now the reported time it takes K9copy to copy the disc is 19min.
