How do you fade an image over video in the VSE I am trying to do video editing and I want an image over the video, but I don't want it there permanently. I want it to fade in and out, kind of like transitioning or animating.
I am not sure how to do this. I have seen it done in adobe premiere and people say that blender is a good free alternative.
In the Video Sequence editor press N to bring out the tool bar.
Then select the video strip you want to fade out and insert keyframes for opacity , change to a different frame, change the opacity and insert a new keyframe:



( to create a key frame hover the mouse over the opacity press the right mouse button or press I)

For other kinds of transitions/efects please refer to the Sequencer Effects Manual
