VERY VERY odd increase in encoding speed, then crash (Training day & CCE 2.50)

I'm no expert - but usually when this happens (I some times get 4.0+, also on an Athlon 1800+) it's avisynth that has experienced a problem. Try viewing the mpv file that CCE has produced. It will probably at some point be black with some red text. The red text is the error message from avisynth. Sometimes it can help you debugging. Dr. Fresh

@pickaxxe. I'm even less of an expert than others, but you might try a short test with the goal of isolating the problem to a specific s/w: Encode several chapters using same CCE settings (CCR, 2350 bitrate) as you did and then using VBR (3 pass w/ 300 min, 2000 avg, 2300 max avg). Compare the encode times and post results if there is a significant difference. Good luck

Well, I just had the "speeding problem" again, with a different movie. And I found out that it was the "sharpen" option that caused the error. What's this with avisynth thing I read about so much?

i think i remember reading somewhere that sharpen crashed some people's encodings of shrek, and when they turned off sharpen, it didn't crash...maybe something about a lot of dark parts and the video bitrate being too low..i dunno anyways, try turning off sharpen. and if you want to read more about avisynth check out a great review on framesersving over at or avisynth.org

If you do a searcg in the whole doom9 forum you will find mention of another sharpen filter called unfilter. You can try that new one and see if it works for you. To use it you would have to edit the .avs file though.
