1st pass high fps 2nd pass low fps

[ny555soul]

I have a C2D E6600 OC'd to 3.0 GHZ and I was averaging 160 fps on 1st pass and 160 fps on 2nd pass using autogk 2.40.For some reason im now averaging 160 fps on 1st pass and 80-100 fps on 2nd pass, and my cpu usage is 95-100%.What would cause such a huge drop in fps?I havent changed any settings and the 30 min test video is the same.

Btw Im using xvid 1.2 with 2 threads.Both cores are being used in task manager with 95-100% usage.
Like i said i havent changed any of the settings but now the fps are dropping alot during 2nd pass.

are you using a more complex avisynth input script?

No i havent touched avisynth.All the settings in autogk are the same as before.Im wondering if it has anything to do with overclocking, but im using cold air to keep temps below 40 degrees C even at full load, so the cpu never got really hot.But even still why would only the 2nd pass slow down?

I wish i had saved my logs, so i could trouble shoot this better, but i do remember one one of the logs saying:
"trying to adjust settings"
"no adjustment possible"
Not sure what it meant, but it was right after the 1st pass.
Thinking that has something to do with it.

Hi,

You can monitor the cpu clock in the process manager (Ctrl+Alt+Del) to see if the cpu throttles ...
Edit: my bad monitor with cpuz, not the process manager.
...but i do remember one one of the logs saying:
"trying to adjust settings"
"no adjustment possible"

Correct, that has to do with the 1st pass which can be redone IF the settings can be adjusted.
If it happens again, post the logfile

OT: 160fps is impressive, I'll have to overclock much more if I want to approach that speed :D /OT

are you using a more complex avisynth input script?Indeed... Most probably generating encodes at a higher resolution...

The more pixels you encode, the lower the encode speed.

Hi,

SMD, he already stated no and it is true in Autogk unless geeks like me use Agkpal :)

Typical script is
autocrop(movie,mode=0,wmultof=4,hmultof=4,samples=10,aspect=new_aspect,threshold=34,samplestartframe=0,leftadd=0,rightadd=0,topadd=0,bottomadd=0)
LanczosResize(out_width,out_height)
RemoveGrain(mode=2)+ colormatrix or leakkerneldeint if used

I just made a quick 2 pass encode of 1 short Vob and had the "Trying to adjust settings" indication and a slower 2nd pass; here is the partial log:

I have my C2D e6600 clocked to 3 ghz with a 4:5 ratio for this test

Actually the "trying to adjust settings" log was when my 1st and 2nd pass fps were around 160-170 fps(depending on how high i overclocked)
Now i dont get the "trying to adjust settings" and my 2nd pass is slower.
Here is a more recent log with 2nd pass dropping fps:

Hi,

@SMD, My apologies. You were right but in reverse: the less pixels to encode the higher the encode speed :)

@ny555soul
Your encode is out of usual boundaries: you have 21% expected quality with a resolution of 512x384 :scared:
You may want to re-read the tutorial http://www.autogk.me.uk/modules.php?name=TutorialEN , specially the part concerning size, quality and resolution.
I suppose your source is an avi and you want to have your movie or clip in a smaller size. If so let AGK with auto width (not 512 minimum width)
I suppose the resolution will then drop below 400 or even 352 width with the expected quality rising to 50% or more.
Let it finish and compare the 2 encodes then choose what fits you best and give us the encoding speed for the other encode -> the 2nd pass should be lower but near the 1st pass speed ...

Temperature could be causing a problem. With core2duo chips, if the temperature hits 70C (or was it 75 or 80?) the clocks will automatically scale down in speed in a manner that won't be picked up by CPUZ or similar. the only program I know of that picks it up is intels Thermal Analysis Advisor (definately a useful tool to have btw).

I use coretemp to read the actual temp of both cores.
My temps never go above 46C on either core even at 100% cpu usage even overclocked to 3.3 ghz with a 1:1 ratio.

@ BigDid

Source is TS (mpeg2) 544x480 i have autogk set to fixed 512 to keep 4:3 ratio and to keep bitrate above 1000 kbs to fit 90 minutes on a cd.But that was a 15 minute length test clip.Custom size of 117 MB

I did notice on the last test i did, during 2nd pass cpu usage went down to 88-93% where 1st pass was a consistent 97-100%, but coretemp never went above 46C and actually dropped to 43C during 2nd pass.
I dont think my cpu throttled at those low temps.

Heres another test @ 3.3 ghz 1:1 ratio :

I have same issue with my amd X2. 1st pass uses 100% cpu on both cores and 2nd pass is quite eratic but generaly used about 90% across both cores. C&Q is dissabled. I have a fresh xp install and a fresh autogk 2.40 install and pretty sure it didnt happen a few versions ago but cant be sure.

My source is 720x576 freeview footage. usualy 45 min tv episodes. minimum width set to 640 and vbr 192 mp3 and a target 350mb file size. Accurate colour fixing, sharp mpeg, and ess standalone support.
