DVD to XviD using GPU

no_1_dave · 14 Jul 2008 at 18:42

I usually convert DVD to XviD using AutoGK but i've decided 1 - 2 hours is too long to wait. Is the software that uses Nvidia's CUDA out yet? Would love to do it in 15 mins. I've also got a 1080p MKV I wouldn't mind downsizing to 720p on the GPU. Anyone know of anything?

Not sure what Nvidias CUDA is but i think 15 mins is a bit optimistic if you want any decent results.

It does the encoding on the GPU so is not optimistic at all. There are some vids on youtube & a good few sites talking about it & demonstrating it. Just nothing new so wondering if it's about yet...

Is it me, or is this a really stupid reply?

Why doesn't it use any processing power available? GPU (and multiple cards) quad core, aegia etc.

Not really - unless I am mistaken, using the GPU isn't going to help that much (from a guess - i might be wrong)?

I mean using a Quad Core at 3.6Ghz with 4GB RAM AutoGK took around 30-40minutes on a single pass for a ~2 hour DVD, and that was after it was copied to the hard drive which took ~20minutes (limited by the read speed of the dvd drive methinks)

The GPU is much faster then the CPU at encoding

Fair enough....I was just going on the fact that all the decent encoders I know are based on CPU encoding, which if what you say is correct, is stupid....

....but then again GPUs have got a lot faster in recent years and the encoders I know are reasonably old.
