I have a video with an overlay that i need to fade in. When i add a crossfade it starts fully opaque and then fades out. The exact opposite of what i want to achieve. How do i reverse the crossfade effect without also reversing the video?
If the overlay has transparency, you could use an Add strip instead. Then keyframe the Multiply setting for it going from 0.0 (invisible) to 1.0 (fully visible).
