Selur's Little Message Board

Hello all, I'm still fairly new to Hybrid so please bear with me. I have successfully used Hybrid in the past to encode avi files from VirtualDub. In this case, I am trying to re-encode DV video in the form of avi files to convert them to mp4, and also to deinterlace. I have attached the debug output. Please let me know if there is anything else you need from me to help figure out this issue.

Okay, seeing that you are using Windows 7 a few things.
Windows 7 was dropped with 2021.01.31.1 (see: https://www.selur.de/changelog), but it might still work iirc. there are a few users that use Hybrid on Windows 7 with the latest version.

Here are a few things you can try:

• check the Vapoursynth Preview and see whether it shows an error, let me know if it works or not.
  Since x264 reports ' y4m [error]: bad sequence header magic' it probably is a decoding problem.
  In case the decoding of the file fails:
  • Since you use DV and before used VirtualDub, you could try whether it helps to enable "Filtering->Vapoursynth->Misc->Source->Prefer AviSource for .avi input". This way Hybrid will look for a 64bit vfw dv codec on your system an in case there is one use that.
    
• change 'Filtering->Support' to 'Avisynth' and try whether the preview works fine.
  • Since you use DV and before used VirtualDub, you could try whether it helps to enable "Filtering->Avisynth->Misc->Source->Prefer AviSource for .avi input". This way Hybrid will look for a 32it vfw dv codec on your system an in case there is one use that. (64bit version in case Config->Internals->Avisynth->Avisynth type" is set to '64bit'.)
    
  • Since ffms2 is used as decoder, you could try using an older FFMS2 version (https://github.com/FFMS/ffms2/releases); 32bit dll belongs into 'Hybrid\32bit\avisynthPlugins'-folder, 64bit dll belongs into 'Hybrid\64bit\Avisynth\avisynthPlugins' folder.
    
• try a later Hybrid version
  

If you can upload a small sample somewhere and send me a link to it I can try whether it's a general decoding issue with your file.
I tried some content with the same characteristics of your file (# color space: YUV411P8, bit depth: 8, resolution: 720x480, fps: 29.97, color matrix: 470bg, yuv luminance scale: limited, scanorder: bottom field first) and had no issue decoding (and encoding to 422 x264) it.

The Vapoursynth script used:
also looks fine to me.

Thank you so much for the quick response! I checked the preview and the log said "Failed to Initialize VapourSynth." Also, I updated to the latest version of Hybrid. I tried enabling the "Prefer Avisource for .avi input," however it still crashed.

I switched over to Avisynth and preferred Avisource for that, but I got the following error when I ran the preview:

Avisynth preview error: -> MDegrain1 : no valid OVERSCHROMA function for 16x16, bitsperpixel=8, lsb_flag=0, level=1 (C:\Program Files\Hybrid\64bit\Avisynth\avisynthPlugins\QTGMC.avsi, line 759) (C:\Users\Zack\AppData\Local\Temp\tempPreviewAvisynthFile15_16_55_602_tmp.avs, line 16)

I can also confirm that it is not one specific file that I'm having this issue with, as I have tried several similar files and have had the same results.

Please don't blindy quote my whole posts, it really makes it harder to read your post. :/

Okay, I can reproduce that problem is that QTGMC doesn't support 411 sampling.
Try:

• enable "Filtering->Custom->Insert before"
  
• set "Filtering->Custom->Insert before" to "Deinterlace"
  
• enable "Filtering->Custom->enable" and enter
  
  Code:

  # adjust color to YV12 (color matrix: Rec601)
ConvertToYV12(ChromaOutPlacement="DV")
# colorformat YV12

that hopefully fixes the issue. (will adjust Avisynth QTGMC handle 411 content in the next release) -> send you a link to a dev version which does the adjustment automatially so no custom code for Avisynth is needed.
