  1. Hi, I would appreciate some help please. I'm using the latest megui 0.3.4.0 and my computer is a Q6600 quad core, using 8gb RAM. I'm trying to encode a movie and the FPS in megui is 1.64FPS - this is crazy slow. . . what am I doing wrong? Any help much appreciated.

    ETA: the task manager says that the CPU is being used at 100%, by x264_64.exe, if that helps.

  2. use faster / lower quality settings

  3. Thankyou....but it is not the case. I should have mentioned that I used to average 3-4 hrs on megui encoding a standard 2 hr DVD movie, at 2pass insane setting. Now I return to it after a few months and it has autoupdated itself but the speed has become too slow. I used to have between 16fps - 20 fps on my quad, but now it's down to 1-2fps and will take over 1 day to encode a 2 hr movie.

    What factors could be involved? I have closed down all other programs to allow megui full use, and it is at full 100% CPU throttle but still the speed remains slow. puzzled and frustrated...

  4. how long ago since last update? "insane" is several times slower now , there are some new features implemented. "insane" is named that for a reason; 10x slower is not worth 1% increase in quality at a certain bitrate IMO. Roll back to an older version if it bothers you

  5. I did try rolling back to megui-0.3.1.1056 but the slow speed has remained, it is like it has infected all earlier version. I don't know why it is behaving so slow when it used to be so fast. I am thinking of purchasing a new hard drive and re-installing windows-xp on it to see if that will make full use of my quad core speed. I wonder if anyone has further suggestions for me...

    May be the source that you are trying to encode is not so good.
    Try encoding the older video source on which you got 16-20fps.. if u get between 1-2 fps on that source too then try formatting your hard disc and re-install windows & your older version of Megui.

    Buying a new hard disc entire for this purpose is not a good option when you have many alternatives to work on.
    Good luck

  7. Use a faster x264 preset. "Slow" or "slower" will be a lot faster. I'm guessing it's some change in the presets that caused it.

    what was the commandline when it was "fast"

    what was the commandline when it was "slow"

    if taskmanager says x264_64.exe is 100% ,then that suggests its your settings, not some other bottleneck like avisynth or filters etc..

  9. Thankyou so much for the replies, SXN, Creamyhorror and Poisondeathray. I reinstalled version 0.3.1.1056 again, and this time did not let it update the core - (had to update everything else or else it would not run). I also installed an earlier version of avisynth instead of the latest version 2.58. And so now my speed is averaging between 28-30, which still isn't ideal for a quad core but miles away from the slow speed I was getting before.

    Thanks for the replies, and you're right SXN, it wasn't worth getting another hard drive when more tinkering did it.
