Exporting a movie with the settings "nearest neighbor"

I must point out that many respondents (the_wine_snob, Harm Millaard, and Ann Bens) simply did not take the time to understand the original question.

However, Ann is half-correct that dynamic-linking to After Effects is one way to solve this. But the "Detail-preserving Upscale" looks like the wrong effect to use. Again, the question is about specifically using Nearest Neighbor upscaling.

Nearest neighbor is essential for upscaling pixel art and old video games, so that the pixels retain their sharp edges, and are not blended into one another.

There is another thread on this topic, but I don't think Fabrazz's answer is correct:

Resizing pixel art video without affecting the pixels with blur.

Maybe the option is now gone in Premiere 2017.1.2, but I can't find ANYTHING that I can right click on to get the menu option "quality," and then "set to draft" inside of that. It would have been extremely helpful if Fabrazz had included a screenshot.

In this thread, the mosaic effect is mentioned as a potential workaround. Heller23 has also mentioned it.

And in fact, it DOES work... but only to a point.

Below, I have footage of a tree in a video game, with the Mosaic Effect applied (using the clip's dimensions, 1920 horizontal blocks by 1080 vertical blocks).  This is scaled up to 600% and it definitely looks better with the mosaic effect.

The Link sprites are scaled to 3000%, but the mosaic effect in this case seems to have done nothing. Link is just as blurry.

Looking at the same image in Photoshop, you can see the result I wanted.

So, here are some answers to this issue:

Option 1: For still images, Photoshop's Nearest Neighbor upscaling can be used.

Option 2: For scaling up to about 500, the Mosaic Effect can be used. Use the same numbers as the clip's resolution.

Option 3: Otherwise, use a dynamic link to After Effects, which (I believe) does have Nearest Neighbor upscaling. But, I'm fairly sure that it's actually called "DRAFT" mode. This is categorized under "quality and sampling," and can be done by clicking a few times on this icon on the desired layer:

(Video explanation here:  Adobe After Effects CC Tutorial | Setting Scaling Quality Using Bicubic Or Bilinear Sampling - YouTube )
Then, you might still need to pre-comp that layer, or even render and re-import, depending on what you're doing.

Lastly, please submit a wishform to adobe and ask to get Nearest Neighbor upscaling into Premiere itself.

You can't get from A to B and keep it sharp in this case.  It's just too much.  Follwoing are the scaling method's PP uses.
