Scaling error - different output resolution

[Selur]

LOL, looking at the preview script, I see what is causing the confusion.
(if you had read the sticky and provided a debug output of calling the preview, I would have probably spotted it earlier)

The Vapoursynth Script View properly shows:

clip = core.std.Crop(clip=clip, left=24, right=24, top=4, bottom=8)# cropping to 672x564
# resizing using NNEDI3CL
# current: 672x564 target: 1440x1080 -> pow: 4
clip = edi_rpow2.nnedi3cl_rpow2(clip=clip, rfactor=4, nsize=3, nns=4) # 2688x2256
# resizing 2688x2256 to 1440x1080
clip = core.fmtc.resample(clip=clip, w=1440, h=1080, kernel="spline64", interlaced=False, interlacedd=False)# before YUV422P8 after YUV422P16
# adjusting output color from: YUV422P16 to YUV420P10 for NVEncModel
clip = core.resize.Bicubic(clip=clip, format=vs.YUV420P10, range_s="limited", dither_type="error_diffusion")
# set output frame rate to 50fps (progressive)
clip = core.std.AssumeFPS(clip=clip, fpsnum=50, fpsden=1)
# output
clip.set_output()

Now looking at the preview script (which needs to use output PAR 1:1)
Hybrid generates:

# resizing using NNEDI3CL
# current: 672x564 target: 1440x1080 -> pow: 4
clip = edi_rpow2.nnedi3cl_rpow2(clip=clip, rfactor=4, nsize=3, nns=4) # 2688x2256
# resizing 2688x2256 to 1440x1080
clip = core.fmtc.resample(clip=clip, w=1440, h=1080, kernel="spline64", interlaced=False, interlacedd=False)# before YUV422P8 after YUV422P16
# adjusting output color from: YUV422P16 to YUV420P10 for NVEncModel
clip = core.resize.Bicubic(clip=clip, format=vs.YUV420P10, range_s="limited", dither_type="error_diffusion")
# adjusted resizing to achieve PAR 1:1 for preview
# resizing for preview to square pixel to 1288x1080
clip = core.resize.Bicubic(clip=clip, width=1288, height=1080)
# set output frame rate to 50fps (progressive)
clip = core.std.AssumeFPS(clip=clip, fpsnum=50, fpsden=1)
# output
clip.set_output()

So it starts with 672x564 (PAR 1:1), then applies NNEDI3 with x4 and has 2688x2256 (PAR 42:47).
This then gets resized to 1440x1080 (PAR 42:47).
And at the end gets adjusted to PAR 1:1 for preview, which results in 1288x1080. (1288 = 1440/47*42)

=> Hybrid is working as intended.

MPC-BE also shows 1288x1080 even if the encoded file is 1440x1080 since it too needs to compensate for the 42:47 PAR.

Ps.: I suspect your input PAR is wrong and should be 16x11 and you wanted something like:

or

(The source also should be flagged as TFF, atm. it is only flagged as interlaced and Hybrid assumes BFF since its SD)

PPs.: Reading [INFO] About pixel aspect ratios,.. and the linked sites might help with any confusion about PAR, DAR,...
