I’m a complete newbie, not quite sure but when i dont interlace with qtgmc the file starts processing, but when i have it on, it crashes i get either a bit it too small error Or helper1, exitCode: 11 error.

Followed instructions to the T

I have an interlaced video i ripped from makemkv
Ntsc 29.97 
I wanted to interlace with qtgmc placebo with 1.50 noise reduction and bob for 59.94 fps. 

I will try and paste the script on here.

[Selur]

May be shijan can say more about it, but

helper1, exitCode: 11 error.

indicates that the decoder crashes, so there is probably something 'off' with the Vapoursynth integration.
Check the Vapousynth Preview, it might give some more details about the problem.

Thanks Selur!
i have reached out to him.

quick question about hybrid. Is the interlace 2-pass scanner accurate?
i ran dgiindex on windows of a ripped tv show from a dvd and it says interlaced ntsc video
however when i run the 2-pass interlace scanner From within hybrid the little white box at the bottom told me the same video was telecined. 

thanks for the help.

Is the interlace 2-pass scanner accurate?

Nope it's a heuristic trying to guess the interlaced state, only way for sure what the source is, is to look at the frame/field patterns.
When the source is Ntsc 29.97 it's probably not interlaced, but telecined.
-> Look at the Vapoursynth Preview to see the effects when VIVTC or QTGMC are used.

Well it’s when i runt qtgmc is when i get that error helper 11 or byte size too small. 
i am running vivtc right now With no issues. 

So neither dgindex nor the built in scanner can tell me. 

I have to say selur, your software is amazing. The ability to see all the options laid out, with descriptions. Clearly this is a labor of love, with how much effort you put into this.
I am a Mac user coming from handbrake this software has a much bigger learning curve.  I wish you coded for handbrake, Handbrake is in the stone age compared to all these new filters.

[Selur]

Happy you have a use for Hybrid, even when the mac version hasn't got any code changes and updates for 2+ years.

I don't need changes, although,
docker is becoming very popular. there are ways to make a thin docker container with a thin install of windows (maximum compatibility with vapoursynth and avisynth) could also be made with a thin linux os.
then the docker apps could be loaded on any system (basically a sandboxed application)

I talk as if I know how to do this stuff but I don’t.. or else I would make one.

so interesting issue. when I run qtgmc on vapoursynth with medium setting it works.

when I drop the setting in qtgmc from medium to slow, slower, or very slow, placebo, or custom. that's when I get a crash because the byte size is too small error,

this is my script for medium which works, will try slow script as comparison.

about your problem:
Different presets use different libraries.
The Vapoursynth Preview should give an error message if a library is missing,...

--
about docker: I have no problem in case anyone wants to setup and maintain a docker container and share it for free with others.
