I am getting AI input and trying one thing. I add the following to beforeCAS in the custom area of VS.
# 0. Load GPU Plugin
core.std.LoadPlugin(path="C:/Program Files/Hybrid/64bit/vsfilters/ResizeFilter/nnedi3/NNEDI3CL.dll")
# 1. THE STRETCH KILLER (Metadata Reset)
# We force the clip to recognize itself as Square Pixels (1:1) BEFORE upscaling.
# This prevents the "Double Stretch" issue.
clip = core.std.SetFrameProps(clip, _SARNum=1, _SARDen=1)
# 2. THE GPU UPSCALE
# NNEDI3CL handles the high-quality 2x jump (720 -> 1440)
clip = core.nnedi3cl.NNEDI3CL(clip, field=0, dh=True, dw=True, nsize=0, nns=3, device=0)
# Final stretch to hit 4K height (2160)
clip = core.resize.Spline36(clip, 2880, 2160)
# 3. PILLARBOXING
# Center the 4:3 image inside the 3840 wide 4K frame
clip = core.std.AddBorders(clip, left=480, right=480)
I concurrently uncheck the resize box and the Convert output to PAR boxes. The enconding processes but the output is stretched vertically. I assume it's a PAR issue and AI keeps telling me that its custom script will fix it but no luck. For completeness, below is the entire script with these changes.
