Best method for video non uniform scaling?

Question

I have a very small video of size 160×210 px. I want to scale it to 1200×870 px, thereby changing its proportions.

What's the best method to achieve an acceptable result?

I tried using the detail preserving upscale, but that effect only performs uniform scaling, while i want to non uniformly scale the dimensions. Consider that the original video is the screen capture of a very old atari game, hence it has very few colors and pixels.

Thank you

I think for pixel art stuff you are actually better off using nearest neighbor scaling. Toggle the little diagonal line until it shows blocks on your layer and then scale non-uniformly from there by unlinking the scale property.

Alternatively, if its not archival footage, you could download a video game emulator (not going to get into the legal argument) and you could try screen capturing that as most emulators have custom built scaling engines for pixel art that do a better balance between detail and smoothness. If you really want to go into the weeds just look here:
