Is there a chance to add the ability to control the effect using key frames like in size / position? This would greatly simplify the work and you do not need to use masks to follow the object.
I know how to do it using masks. As it would be possible to use key frames in the Section, creating a given effect would be easier and would not take up so many video tracks. With 9 films with masks, we have 18 tracks in the project. Example
. . . . With 9 films with masks, we have 18 tracks in the project . . . . would not take up so many video tracks . . .
Are you trying to create a 'video wall' ie have all 9 films on the screen at the same time, or are the nine films one after the other behaving as you have shown above and then each one zooming the section to full screen?
This discussion is going in the wrong direction. I asked a simple question. Will key frames be added in Section? How to do it now in Pro X I know. You do not have to explain it to me. So again. Will keyframes be added in the future section?
