Possible to use 2x scale with realesrgan-plus?

It seems like I cannot reduce the scale from 4 to 2 with realesrgan-plus Model. It is locked at 4.

I can only reduce it to 2 under realesr-animevideov3.

I'm looking to upscale a real-life video, therefore my preference is to use realesrgan-plus instead of realesr-animevideov3.

It takes a bit too long to do 4x upscaling and then downscale to 2x.

Unless realesr-animevideov3 performs just as well for real-life videos, I would prefer to use realesrgan-plus for this upscale job.

Any help or clarification would be greatly appreciated!
