Smooth Transition - GoPro Concept

After an quick user research, competitive benchmarking, and sketching, I made this prototype to present my ideas to GoPro french and US team.

Today it's not possible to edit precisely transitions in GoPro app (just with templates).

I proposed interface to personalize transitions with some smooth transition like slide, zoom...

(I know this is the same video in the player, the focus wasn't there :D )
