Scaled proxies contextual menu items for media library are a bit confusing and inefficient
The workflow with the contextual menu item to switch between the three possible live playback types of a clip in the media library, is a bit cumbersome, because it shows only one or two options at a time instead of showing the three possibilities, so it makes you go through the whole "original <--> HQ proxy <--> scaled proxy" chain if you want to go from one extremity to the other. It's also not necessarily clear that these apply (I think?) only to live playback.
It would be clearer to use a set of "radio" group items, such as:
Open containing folder ----- ( ) Use original file for live playback (slower and less stable) ( ) Use high-quality proxy version for live playback (faster) (o) Use low-quality proxy version for live playback (very fast) ----- Delete corresponding high-quality proxy file Delete corresponding low-quality proxy file
