Talk about intensive learning. This may be very interesting for people who want to rip DVD's to avi format using a complex processor:
I've tried a lot (and I mean a lot) of programs out there that convert DVDs to DivX, Xvid etc - including DVD Fab and #1 DVD Ripper which are supposed to be among the best, with my Intel Quad 2 Core, they run at around 50-60 frames per second (fps). As well as recording the fps, I also take note of the Vista Task Manager for all four processors. One of them is being utilised fully but the others don't. They fluctuate, but are not comprehensively utilised.
I tested the same DVD with a program called Auto Gordian Knot (AGK) and the real kicker is that it's freeware. It's brilliant and utilises the system resources available. I thought I'd put it through it's paces with a 2-pass transcode with the Xvid codec. Here's my results!
The program uses a number of smaller programs including VirtualDub. I can either set a thread priority manually per movie or default it - I default it at highest thread priority. With a Quad 2 Core, who wouldn't, right!
I went a step further and looked at the priority in Task Manager. It was set to low so I changed it to high, then real-time. The strange thing is that setting a higher priority in task manager lowered the fps substantially. I changed it back to the default of low.
To understand my results, here's my system specifications:
22" high definition widescreen LCD monitor running 1680 x 1050
Asus motherboard at 1066 Mhz
Intel Quad 2 Core 2.6GHz
3GB DDR2 RAM
Nvidia 8600GT 512mb
2 x 500gb HDD
Windows Vista Ultimate
Other stuff that's not important for this test.
The results are based on the same DVD residing on my hard drive, encoded to a second hard drive using the Xvid codec. Note that the average fps with other programs like DVD Fab was around 50-60 per pass using the 2-pass method.
- First pass 130-150 fps (15 minutes)
- Second pass fluctuated rapidly from 60-220 fps (the result was an average of 110 fps) (22 minutes)
- The avi product after encoding was far greater than any other product I have tested.
- Even on a high definition 22" LCD monitor, it looks great at full screen. Much better than other programs.
- The file finished almost 15 minutes quicker than any other product tested.
- There's no sound in Windows Media Player or Windows Media Center. There are audio options and I assume one of them will work (note that the product using Auto settings did work on my DVD Player which is weird).
The download link for AutoGK is http://www.autogk.me.uk/
It installs VirtualDub as well but remember that to set the thread priority in VirtualDub before using AGK. I'd be interested in any results for the DivX codec, but I prefer XVid because it's free.
Hope this helps! I definitely recommend AutoGK.
