Gordian Knot w/ DivX 5.1.1

[divxdude]

has any one tried it out yet. if not ill be happy to give it a go around to night, and give my thoughts on it.

I have tried it but switched back to v5.05. It is tooooo slow. Slowest gave me an output of 6 fps on a P4 3.0gig! Although, over at DivX they claim that standard 5.1.1 = slowest 5.0.5 as far as speed is concerned but I didn't stick around to mess with it. I wanted my speed back. As far as the newest Gordian Knot goes, hold off on that because it seems to have a memory leak in it while doing a compressibility check w/ VdubMod (but not during the actual encode). So I downgraded that as well. Hope this was helpfull.

[divxdude]

weird.

i just finished testing mine. did a compressibility test at with these options.

512x368
little noise
Lanczos (Sharp)
Field Deinterlace
5% compressibility
Birate 1531

encoded first pass and second pass at 22.5 fps.

this is way faster then 5.1

What are your system specs?

[divxdude]

P4 2.8ghz w/512k cache
ASUS P4TE MB
640MB RDRAM
Windows XP w/SP1
Black Vipers Windows XP Services Disable patch

Gordian Knot 28.6.3
DivX 5.1.1

[georgiek50]

Did you follow the guides over at DivX on increasing speed or you just happened to get right from the start? Also, do you really notice such a big quality improvement that would make it worth losing 25-50 extra fps?

[divxdude]

nah i didnt read any guides. as far as quality loss, i think 5.1.1 is a bit more crisp and clearer then 5.0.5.

For the codec settings i uncheck disable post prcessing, set automatic post processing to Full. Deringing and Deblocking to full.
Enabled Bi-Directional Encoding and GMC. I also had the divx profiles disabled, theres really no use for these.

positive results

i have been doing my endoding with 5.1.1 and gknot. my fps is between 60-90, but will finish in the 60's. only problem here is with playback. i have dual monitors and i play a video on one monitor while playing a video game on the other. it used to work fine with 5.0.5, but now the video won't keep up with the sound.

[georgiek50]

frell,

Can you post some computer specs as well as setup for encodes. I am really curious to see 5.1.1 with some good speeds. From your fps it sounds like you a "trual" (not dual) CPU...please, shed some light.

[frell]

i got a p4 3+ghz with hyperthreading, 800 mhz bus... earlier tonight i was watching a divx movie and encoding at over 60fps. i use default settings with 5.1.1.

[georgiek50]

Hmmmm....I have the same exact specs, except I got 6 fps when I tried encoding with it!!! Did you disable anything in there?

[B|izz]

60-90 ? woah.
Using Gordian Knot w/ DivX 5.1.1 on my 1.4ghz AMD laptop I get around 4.2 fps and it takes AGES !!!

How do I speed it up?

Watching movies and encoding at over 60fps???

i highly doubt that. no offence but encoding takes about 90% of your processing power. Doesnt matter how fast your processor is.

[georgiek50]

Actually I think it's highly possible as long as long as 60 fps is there to begin with. I have the same exact specs, I get between 45-80 fps but never up to 90...and mostly I'm in the 55-60 range (but w/ 5.0.5 not 5.1.1) and watching a movie while encoding doesnt' seem to slow it down by more than a few fps.

[frell]

when i switched to 5.1.1 my speeds jumped bigtime. and divxdude, i'm sorry but your knowledge of how computers work appears to seriously be lacking
