Please add function – No Crop Video Square Fit Review

I appreciate what this app does but I wish that it would have a function to maximize the frame ratio of iPhone videos to the portrait ratio allowed on Instagram, instead of just the two extreme options of fitting or filling a square frame. In other words I would love if you could "fill" the portrait ratio for IG, not a square. That way my video will show up as big as possible without cutting any part off. Please add this! Thank you in advance!
