  1. Please help. I have the latest version of Staxrip and Avisyinth+ with it. I saw a preview of my video and I personally think that mClean does a great job, but when it starts to encode the 2 pass it crashes. I don't know how to fix it. If there is a better denosing algorithm please tell, but I do prefer mClean right now.

  2. Is there an error message?
    Check the log file for messages

    Are you computer temperatures ok ? overheating ?

    Does it encode ok without mclean ?

  3. It encodes just fine without the mClean filter and no my computer doesn't get hot. Here's a screenshot of the error message. Just to clarify this was just a test so I could show you guys the error message. My actually video is 30 minutes while this was 2 seconds.Image

  4. I know that it's the mClean filter that is doing it

  5. Can you post the actual log file ? There should be more information. It should be a text file somewhere

    That error message is for the 2nd pass. That suggests the 1st pass completed - If that's true, then mClean isn't the problem

  7. It looks like the wrong log . This one uses x265, and it completes the 2nd pass

    Code:
    Video encoding second pass using x265 3.1+11-de920e0 Wolfberry
    .
    .
    .
    encoded 101 frames in 31.39s (3.22 fps), 10395.64 kb/s, Avg QP:23.65

    I did some test with x265.

    This one should be with x264

  9. No error messages in that log. It shows everything completed

  10. I'm sorry i'm really new to all of this. wait a little bit and I'll find one

    I cut the video to 10 seconds. This video was originally 30 minutes, but it still fails with mClean

  12. I don't know .

    The 1st pass doesn't complete. I've never seen the "bad sequence header magic" error . There is some issue before x264 gets the data. It doesn't make sense because other encodes complete using the same tool chain

    Code:
    avs2pipemod[info]: writing 476 frames of 50/1 fps, 1920x1080,
    sar 0:0, YUV-420-planar-8bit progressive video.
    y4m [error]: bad sequence header magic
    x264 [error]: could not open input file `-'
    What versions of avisynth and avs2pipemod are being used? Maybe try updating them

    Take "D:\Videos\Klods Hans\VTS_01_1_temp\VTS_01_1.avs" , and open that in vdub2 . Scrub through the timeline and check if there are any error message

    Code:
    MPEG2Source("D:\Videos\Klods Hans\VTS_01_1_temp\VTS_01_1.d2v")
    QTGMC(Preset = "Medium")
    mClean()
    nnedi3_rpow2(rfactor=2,cshift="lanczosresize",fwidth=1920,fheight=1080)
    Trim(0, 475)

  13. avs2pipemod 1.1.1

    Avisynth+ 2772

  14. It might have something to do with just the x264/x265 encoing

    I don't remember having seen 'bad sequence header magic' before. For 8 bit input you can disable the piping tool in the x264 options Other tab, x264 supports 8 bit avs input, no need for piping in this case. I just recently made avs2pipemod the default in 2.0.3.0 because x264 don't support 10 bit input, it only supports 8 bit and 16 bit input. Alternatively to no piping tool and avs2pipemod you can also choose ffmpeg as piping tool, like avs2pipemod this supports both 8 bit and 10 bit input.

    Yeah, it's not an x264 issue. It means something before it is failing. AviSynth (the script) or avs2pipemod.

  17. I don't know what the piping toll is and it is not in the other tab or maybe it has a different name.

    I just think it's weird that mClean is what is causing it. Tried it without and it works just fine

  18. It works ok with mclean for me, using avs+ r2772 , avs2pipemod64 1.1.1 , same script on a PAL source like yours, just using the commandline to x264 r2935

    Maybe issues with that specific x264 binary

  19. I'm gonna keep trying to fix it, but if there is a better denoising algorithm, then please tell. Because it doesn't have to me mClean, unless that is one of the best denosing algorithms.

    Have you tried the script in Virtualdub2 to see if it works properly (this was already suggested by poisondeathray above)

    Virtualdub2 will open the script via avifile api just like the staxrip preview, the staxrip preview adds converttorgb and convertbits 8

  22. I tried running the script in virtualdub2 and It seemed to work fine.

    But bigger news is that the mClean filter seems to work with the "Quality" preset on staxrip. I used 2 pass before

    2 pass only works sometimes with the mClean filter. I'm not sure why. I'm guessing it's fine to just use the "Quality" preset as it seems it does as good as 2 pass, but I could be wrong.

  23. 2 pass is as good as crf right?

    Because I've heard some people say it is and others say it isn't.

    If the resulting bitrate of the CRF encode is similar to that of the 2-pass encode, then the quality will also be very similar. Of course, there's no way to know that in advance. But, unless you really need a specific filesize for your result, better might be to make a quality-based encode.

    If this mClean doesn't work well in StaxRip, why not try a different denoiser?
