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.)

I do agree would be nice to set the scale via height as well, adding that as feature request.

I actually "cheat" by not doing any math myself, and let ffmpeg do the scaling, so I don't have an easy way to display what that will be. For example, changing it to 1920 width with keep aspect set will add the filter scale=1920:-8. Which means that it sets the width to 1920, and keeps the aspect ratio of the height to the nearest divisor of 8 (as some encoders are picky about block size).

I noticed that FF isn't able to correcty detect autoutocrop for 4:3 FHD (1440x1080) sources...

Neither for 2.76:1 (1920x696)
