Expected behavior of the wanted feature

• Video demo of how the feature works

• Text description with images

It is obviously not a perfect solution to stretching, but it is good enough to be of interest to users. Combined with automatic black bars detection, it could let people watch movies often changing aspect ratios in one format.

I wrote a shader a while back with the express purpose of getting as close as possible to MadVR Envy's NLS+, you might want to give it a try: NLS#

There's also an autocrop script for getting rid of hard-coded black bars automatically (autocrop.lua) and another one that tries to do the same thing continuously (dynamic-crop.lua), although it was a little unstable when I tried it.

@NotMithical Awesome! I wonder when we will be able to use some of the more advanced video retargeting techniques for stretching in real-time...

See for instance:

• Video Retargeting: Trade-off between Content Preservation and Spatio-temporal Consistency

• Optimized Scale-and-Stretch for Image Resizing
