[HELP] no preview window with vaporsynth qtgmc
#4
If you just double the resolution, you should not use stepped resizing at all.
Look at the code that is creates and what your settings are doing.
clip = core.std.AddBorders(clip=clip, left=1, right=2, top=0, bottom=0) # add borders to archive mod 4 (NNEDI3(CL)) - 680x564

clip = edi_rpow2.nnedi3_rpow2(clip=clip, rfactor=2, nsize=2, nns=4) # 1360x1128
clip = core.std.Crop(clip=clip, left=2, right=4, top=0, bottom=0) # removing borders (NNEDI3(CL)) -  1354x1128

So I would recommend:
a. clear the temp folder you are using
b. use sane settings

Dev versions are in the 'experimental'-folder of my GoogleDrive, which is linked on the download page.
