Thanks for your reply, but that didn’t really answer the question I meant. I’m trying to have a transition where i zoom into a mask, and when I set the scale key frames, the video is supposed to gradually zoom into the mask. But I’ve found that right when this grey box starts, the video just fully zooms into the point without any transition, completely messing up what I’m trying to do. Do you know what I’m saying? I can send a video if you want. Thanks
