Hi all! I am new here and first of all wanted to great all.

I am composing a video from tracks that I resize and place in a certain position of the frame. With the Pan and Zoom tool and the Composite transition effect. The thing is that I have a lot of so call "air" and would like the background to be either white or transparent. Does anyone knows how?

all best,

tustu

Add a color clip to a track below. Then, on your transitions, set With track to the track with the white clip.
