Make proxies automatically get the correct aspect ratio

Yep, I would like to simply put my desired width (I make most of my proxies 1920) and have it automatically scale the height accordingly. If there's an extra row of pixels, just crop them, or offer the user suggestions on the next closest evenly divisible resolution.

This is what I do manually anyway, and once I do it for my main cameras (GH5 and GH5s) I don't have to do it again, but still a pain to figure out and create a new preset every time I edit footage from a new camera.

I think there are some technical difficulties involved with this one... but yes... having proxies at the wrong scale has caused me many problems, and resulted in me hardly using the feature.

While it may be difficult to create proxies in any given resolution, it should not be too difficult for those proxies to automatically stretch themselves into the correct aspect ratio.
