up-scale, a new small and simple Upscaler

[ProWo]

Here is a small video upscaler. It is portable, for x86 and x64 Windows systems and requires .Net 4.6.1.
You can load any video and an Avisynth script will be generated; this can be edited if desired and previewed/controled with VirtualDub.
Then just click Encode and the video will be encoded.
You can also load your own Avisynth script if you wish. In this case the program simply works as h264 encoder.

The following Avisynth plugins are required:
ffms2.dll
DeDot.dll
Nnedi3.dll
aWarpSharpMT.dll

Enjoy it.

Tested with Avisynth+ 64bit with 64bit plugins
It needs a static build of ffmpeg.exe.
For a x86 computer you need of course avisynth 32bit with 32 bit plugins

Re: Down-Scale Use.

I just found your “up-scale, a new small and simple Upscaler” post.
It is a weird coincidence, a little bizarre that I find your program post.

I use Topaz 1.3.8 Gaia CG, because it is the best version.
As with other versions It creates various patterned artefacts that follow shapes.
I create noise profile and remove with Neat Video.

My point being, I am interested in your upscale.
I process material many times and save to Lagarith AVI.

As mentioned in my post:
When upscaling I use whole numbers, then reduce the final result to specific dimensions.
When CD content has metadata DAR, standard upscale, then reduce one dimension to match DAR.

I have used Lanczos before on tiff images but not with Avisynth.
It required another command to force size if not matching original dimension ratio!

---------------

Would you consider these Down-Scale features and save to Lagarith AVI for your program?

You can change or customize the created Avisynth script as you wish.
If you then need a lossless encoding for further processing, simply select CFR 0. This is equivalent in quality to Lagarith.
The generated video file will be very large though.

[Sandfly]

Would CFR 0. be the same size as Lagarith AVI.
If larger, is it possible to include VirtualDub2 which I already use with Lagarith?

I have not found the Lanczos command to force size if not matching original dimension ratio!
Perhaps it is not required with Avisynth?

That is great the program can already do what I was looking for.
Interesting what hello_hello has posted about fine tune improvements in quality.
I am very noticing of subtle differences in quality, as they keep adding up a little at a time.

Thanks for the info.

You can use VirtualDub2 twice:
First, to control the avs created by Up-Scale.
Second, as encoder with any codec avaiable (g.e. Lagarinth). In this case Up-Scale is obsolete.

I like your script but ain't it a bit too sharp? Using 2 sharpening methods will introduce halos. I suggest adding dehalo alpha to your script. Besides Spline64 produces some ringing artifacts. Spline36 is better suited.

Thank you for your advice.
Post here your concrete suggestion for e.g. an upscale from 1280x720p to 1920x1080p, then I will check it and adjust my script if appropriate.

[joearmstrong]

Code:
dehalo_alpha(rx=2.0, ry=2.0)
Sharpen(0.2)
aWarpSharp(depth=5)
nnedi3_rpow2(2, cshift="Spline36Resize", fwidth=1920, fheight=1080)

This should produce a less sharp result but better quality because of less halos and ringing.

Ok, i've adapted the code.
