I am trying to do a mask, but have problems with it. I am quite new to Premiere Pro.
I am making a historic documentary and want to show bomb bursts on a map.
I have a map and a video with a bomb burst. I place the map on Video 1 and the video with the burst on Video 2 and a Title with mask on Video 3. Then I place a track matte key on Video 2 and point it to Video 3. The mask is needed because the video with the burst is not transparent enough. It darkens a moment and then shows its boundaries clearly.
The mask worked fine when I made it in a trial project: you see only the wanted part of the burst video.
But when I try the mask in the documentary project, the mask doesn’t work. There I don’t even see the burst until I place a check mark with Reverse.
I wonder what I am doing wrong? As far as I see I do exactly the same thing when I make the title mask.
