Adding 2x zoom level to Slow Mo video recording

Interesting idea, but this is not where Apple looks for suggestions.

Apple's official feedback/suggestion/comment portal for such matters starts here:

Yes! Please add this. No reason we shouldn’t have the same zoom levels as the regular camera. Going from 1x to 3x is too big of a jump. For sports slow motion recording purposes for golf and tennis lessons having 2x would make a lot of sense. And just in general to have a consistency of options.
