Hi all ! Sorry if this has been asked before. I am a AE beginner. I searched *a lot* and couldnt find an answer here or anywhere else. I am surprised because what I am trying to do is indeed very simple. I have I video of a face. I am motion tracking the nose. I want to flip the nose vertically. just the nose. I tried a lot of stuff. normal flip flips me the entire video. Putting a mask and doing a transform makes the mask itself flip, not the video that it contains . Applying an effect like mirror or distort makes the image goes crazy, like the referential point is somewhere else. So How could I do a simple vertical flip of a video area, like the nose for instace ?
