Aspect Ratio improvement - presets.

I think the Width / Height / Aspect Ratio is confusing since you can only select Width, and Height will be automatically calculated to fit the ratio (or manually entered). When entering a Width, the auto Height does not show.

By comparison, in Handbrake, when you select a dimension, the other field shows you the resulting auto-fit dimension. I think something like this would make it easier to think about size changes when going from 4K to 1080p for instance, given that a lot of movies are cropped to different sizes.

Ultimately, I decided (I think) that the 1920 width is what's relevant, and I should trust the auto calculated height. But it would be nice to feel more comfortable knowing the sizes before committing to convert. (And/or provide a drop-down with standard sizes like 1080p, 720p, etc.)
