Hi Luca,
From what I found the player maintains the frame rate of the clip when it is uploaded. What that means is that if a 30fps clip and 60fps clip are in the same project they will retain their frame rate and the player will switch between 30 and 60 fps depending on which clip is currently playing.

Has anyone attempted to include clips with different frame rates within the same project? If so what happened? Does it keep the native frame rate or does it re-render to a standard rate?
