I'm trying to do a clipping mask a video to an image in After Effects. Basically, I'm putting this video on top of an iPhone but track matte settings doesn't seem to be working for this. I saw Luma Inverted Matte setting works for what I'm trying to achieve but it leaves my video with like a white overlay on top (see screenshot).
I've already searched the ends of Google for this but can't seem to solve the problem. All I'm really trying to achieve is post my XD prototype on Dribbble but to do so, I had to record my screen, import it to After Effects and now deal with the iPhone background. Please help!
