[HELP] Input resolution not divisible error

[Selur]

File "src\\cython\\vapoursynth.pyx", line 3123, in vapoursynth.Function.__call__
vapoursynth.Error: Analyse: failed to retrieve first frame from super clip. Error message: Resize error 1027: image dimensions must be divisible by subsampling factor

that makes sense.
Content has a resolution of 720x486, so divided by into the two fields each has 720x243.

[clip] = beforeDeinterlace(clip)
# clip current meta; color space: YUV422P8, bit depth: 8, resolution: 720x486, fps: 29.97, color matrix: 170m, yuv luminance scale: limited, scanorder: top field first, full

I've inserted # requires mod 2 before QTGMC. Same behavior, but padding is visible in the generated .vpy script

This should have no effect, since the input (720x486) already is mod2.

[clip] = beforeDeinterlace(clip)
# clip current meta; color space: YUV422P8, bit depth: 8, resolution: 720x486, fps: 29.97, color matrix: 170m, yuv luminance scale: limited, scanorder: top field first, full height: true

Does indicate that nothing was done,.. resolution didn't change

clip = core.std.AddBorders(clip=clip, left=0, right=0, top=0, bottom=2) # add borders to archive mod 4 (vsQTGMC) - 720x488
# Deinterlacing using QTGMC
clip = qtgmc.QTGMC(Input=clip, Preset="Medium", InputType=0, TFF=True, TR2=0, SourceMatch=1, Lossless=0, opencl=True) # new fps: 59.94
clip = core.std.Crop(clip=clip, left=0, right=0, top=0, bottom=2) # removing added borders from mod requirement (vsQTGMC) - 720x486

should work,...
argh,.. mvtools internally does 3 divisions,..

I probably always force mod16, just to be same => looking into it
