Hello,
My encoding is crashing for no reason I can seem to figure out. I have not made any changes to my defaults and such. So, I don't know what the deal is. I am also wondering if it is related to Vapoursynth, as it seems I've been having some stutter-y deinterlacing recently. But I can't confirm that yet. Just a hunch.
Anyway, all I'm trying to do is de-interlace a VHS capture, while using cut support and cropping, and encoding it into an MKV via x264. Here is the debug file.

During the analysis FFmpeg reports some unknown data in the video header data:

x264 reports: "y4m [error]: bad sequence header magic" which usually indicates some problem with the Vapoursynth script.
Does the Vapoursynth Preview work?
The Vapoursynth script itself seems fine:

One thing you can try, assuming you got a vfw version of the codec installed which the source was captured, is to enable: F"iltering->Vapoursynth->Misc->Source->Prefer AviSource for .avi input". This way Hybrid will use AviSource assuming the right vfw codec is installed.

Sorry for the late reply.
No, sometimes the Vapoursynth preview does not pop up.
After applying the suggested setting, it still crashes on the same step. Debug attached.
Also, after I made that change, it took much longer to extract the wav/pcm audio. Like, considerably longer than usual.

Vapoursynth settings have nothing to do with audio extraction. Maybe some over active virus scanner or similar at work?
Vapoursynth script, now uses AviSource as expected:

=> try whether adjusting the crop values, so that the width is mod4, not just mod2, helps.

My crops are mod 4 (multiples of 4, correct?). Are you also referring to my letterbox borders?

Sorry, yes.
I suspect the problem is with:
# letterboxing 702x468 to 720x480
clip = core.std.AddBorders(clip=clip, left=9, right=9, top=6, bottom=6)
If this is the case, I can probably write a workaround, by making sure the content is converted to YUV444 beforehand and converted to YUV422 afterwards.

Sorry, I was wrong. I deleted my comment as soon as I wrote it. Eighteen is definitely not a multiple of four. 😅 I am tired. I changed it from 18 to 16 and it has started encoding at least.

I restored your post.
I did a small test and from the looks of it, the problem is the AddBorders.
I assumed AddBorders with YUV422 would allow uneven left&right, assuming the sum is even again, which it does not.
=> send you a link to a dev version which should fix the problem. (by doing the mentioned YUV422=>YUV444=>letterbox=>YUV422 trip)

Sounds good. In the meantime, changing the 18 to a 16 did the trick (and then splitting it to 8 and 8 instead of 9 and 9). I will have to give the dev version a try to see if I can use odd numbered crop settings.
Thank you!

Ok, let me know how it works out.
