Whats the optimum (if not the best) hardware for ripping dvd into DivX?

[tornedo]

Any comments/input are appreciated...:)

Video Processing is mainly dependant on your CPU in conjuction with your RAM Speed. With my Machine I can encode DivX in realtime ~30fps. Your Hardrive Speed also has hand in the actual copying of VOB's to your drive.

Well i hope this helps you

Hey thanks for the reply.

I got an AMD 1.1G processor and a 256mb ddr ram....with Raid-0 40gb Maxtor 133.

Was having CPU running at 100% for a few hours during dubbing....taking very long time.

Thats why i am checking what to improve.

I did a little testing with a 1.2G TBird, SDRAM, Win2K and XVID. Brief results:

CPU speed is obviously important for a 100% activity like encoding. Encode increased by about 40-50% of the increase in CPU speed (using a multipler OC so all else remained the same). Clock-FPS(scaling% over prior speed): 800-9.23, 1000-10.37(49%), 1200-11.35(47%), 1400-11.96(32%). The last interval scaling result seems a little abrupt but I didn't explore it further. Scaling should be better with CPUs with more cache and faster (DDR/RDRAM) memory.

The HD speed didn't matter with the single exception of wanting to be DMA mode rather than PIO as this adds about 10% to the speed and triple my LAN transfer speeds. I tried an old slower 13.6GB HD and new 30GB HD which benches about three times faster. I tried C->C, C->D, D->C and D->D for source and destination files and the results were within 1%. So certainly make sure you are in DMA mode -- I had re-assembled the machine but not finished the process and was certainly glad when I corrected this oversight.

Minor gains:
(a) increasing the FSB (and memory) while maintaining relatively constant CPU clock -- IMHO possibly not worth the possible drop in stability
(b) 2-bank and 4-bank interleave -- definitely do this one
(c) more agggressive memory timings -- IMHO not worth the possible drop in stability

Final trivia: Oddly enough I got results that were slightly faster when I left OGR running in the background. I have seen this with other benchmarking and think it most likely an error.

Yo pt7,

Good findings you got there...:) Thanks for sharing the info. I am sure a lot of people will benifit from this.

Some inputs from other forum...

btw, SCSI has nothing to do with DVD ripping, don't think it makes any diff.

Thanks MacC for your input.....

I also have the same thinking. Just that to have a Intel dual cpu config is a bit expansive.

Just wonder hows much the AMD dual cpu going to be...cheaper and better performance?? Or not yet proven....

Any other input guys?

[Hiro2k]

MacClipper was right when he said that SCSI has nothing to do with the encoding speed. However It does make a difference if the scsi is in a RAID array. But the benifit of raid is only usefull in large sequectial writes, which isn't available in any version of Windows since it just writes file anywhere on the HD.

But the most important issue when encoding anything DivX is the filters you use! I can't stress that enough. Running any kind of IVTC instead of Force Film will result in longer encodes. Doing any type of De-interlacing will also slow down your machine considerably and there is little that you can do about it.

Hope this helps any :)

I was think about upgrading hardware or setup...
-tried and now running ide raid-0....improve hdd performance
-What u guys think about dual cpu setup? Anyone on dualie care to comment?

[luminous]

My setup is as follows:
amd xp 1800+
epox 8k3a+
512mb pc2700
16x pioneer dvd
etc, etc

it takes about 15 minutes to rip a dvd, then about 3-4 hours to encode it with divx 5

[tornedo]

Anybody else wanna share their experience....any dual cpu systems owners?

[xox]

is the type of video card also important? I mean, would it help to have more ram/power in the video card? or chipset type?

[da franksta]

duals: some increase in speed, but main advantage is being able to run other programs smoothly while ripping.

video card is not important.

[inoteb]

My setup :
PIV 1.8A
2x256MB Rambus PC1600
Pioneer DVD 16x
IBM HD (AVVA 80GB)
Win2k SP3 (NTFS)

120 minutes DVD movie takes me :
#Rip & audio demux (SmartRipper) : 15 minutes
#Audio encoding : nothing for AC3 track (!); 15 min. for LameMP3 160 kbits (BeSweet) or 20 min. for OggVorbis 0.400 surround (OggMachine)
#2 pass video encoding (DivX5 Pro in VirtualDub with AviSynth frameserving) : max. 3 hours 1/2 (1st pass : less than 2 hours, 2nd pass : less than 1h30).
Fast enough for me :)

But many others S/W settings are affecting (each one a little bit) encoding speed (iDCT algorithm, deinterlace, resize filter, etc...)
