Replacing:

if clip.format.bits_per_sample != 8:
        clip = vs.core.resize.Bicubic(clip, format=clip.format.replace(bits_per_sample=8))

with:

if clip.format.bits_per_sample != 8:
        if clip.format.sample_type == vs.FLOAT:
            clip = vs.core.resize.Bicubic(clip, format=vs.RGB24, range_s="full")
        else:
            clip = vs.core.resize.Bicubic(clip, format=clip.format.replace(bits_per_sample=8))

does seem to fix the problem. (in propainter_utils.py)

Hi Selur,

could you clarify better the problem ?

When using the attached mask, it crashes with the above error message unless I change the code as I did.

But the 1-bit mask is an image, while you are getting error on the clip.
Please provide a complete sample with: clip + mask + script

Doh, you are right.
Here's a link to the source: https://www.mediafire.com/file/nxspwubdhbbixyn/1_re-encode%252C_no_filtering.mkv/file

I tested on my side on R74 and it is working.
Please try to test on R74 to see if it works also on your side.

If, as I suspect, is a problem introduced in R76.
You should open an issue to myrsloik on Vapoursynth.

Will do some testing tomorrow, got my gpu busy till tomorrow. Tongue

RE: ProPainter Vapoursynth filter - Dan64 - 14.06.2026

I tested it with the last dev version with R77 released today, and it works with no issues.
Given that you are using 1-bit mask you should use: mask_enhance=True, but in any case it works also with mask_enhance=False.

I noted that in the R77 bundle there is the folder vsdeoldify with about 4GB of models that can be removed, because is not used any more.

P.S.
to read the source I used: core.lsmas.LWLibavSource()

Can you be more specific which pth files are no longer needed?

using R77, it works.

RE: ProPainter Vapoursynth filter - Dan64 - 15.06.2026

as you know vsdeoldify has been substituted by vshavc and in your bundle all the models (about 4 GB) are correctly located in the vshavc folder.
But I noted that in your bundle there is also the folder vsdeoldify with about 4 GB of models and no *.py.
I don't know the reason, but this folder can be safely deleted (unless you are using links that are substituted by physical files when put in the archive).
Please check.
