oh, i found the LanczosResize, it's in the tab of Avisynth -> Line -> Resizer
Here is one of my tests described further here https://forum.blackmagicdesign.com/viewt...3&t=109259
Use NNEDI3 neural network resizer. It removes jaggies upscale artifacts on contrast diagonal lines, but doesn't add artificial oversharpening. On maximum settings it is very slow. if you use NNEDI3 Resize, it always use only its internal resize method (looks like based on Lanczos) and don't depends of Resize method selected in "Crop/Resize" tab at all.

Here are SD to 1440x1080 renders additionally 200% magnified to see the difference:
Here is another interesting test. Poor quality chroma edges from miniDV camera where magically fixed by NNEDI3 resize. Further NNEDI3 Upscale to QHD (1920x1440) and UHD4K (2880x2160) compare to HD makes almost no real difference in quality even if compare side by side on UHD4K timeline.
Some people recommend 960x720 as a master copy for deinterlaced video because 1280x720 @50fps allows to playback from bluray disc, but as you can see NNEDI3 resize to 960x720 looks slightly softer than NNEDI3 resize to HD.
Another interesting option is 1556x1152 (this is dual 768x576). It allow to crop Hi8 tape black borders and fit source to 1440x1080 in Resolve without additional upscaling step.
Tests made on UHD 4K timeline:
QTGMC SLOW-FTS0, NO RESIZE (same quality produce simple Lanczos Resize in Hybrid)
QTGMC SLOW-FTS0, RESIZE to 720p NNEDI3-32-N2-P2
QTGMC SLOW-FTS0, RESIZE to 1080p NNEDI3-32-N2-P2
QTGMC SLOW-FTS0, RESIZE to 1440p NNEDI3-32-N2-P2
QTGMC SLOW-FTS0, RESIZE to 2160p NNEDI3-32-N2-P2
it seems nice, can you do test using my DVD video clip? as high definition as possible, i want to see the effect you make, thanks
here is my upload, 31.6MB MKV, you can change English at right top of the page
