I want to add titles to a video (like the titles in the end of Sintel) using the blender video editor. I made a long Image using GIMP and I want to scroll it in the end of the video. Probably I need to set a dynamic offset, but I didn't find an option for this.
You can do it on the compositor.
Mix the video and the image for the titles. For scrolling titles, add a translate node and animate its values.
If you must absolutely use the VSE, add a transform srip:
To animate the values, go to frame where the motion begins, hover the mouse over the Y position for the effect strip and press I to create a key frame. Go to the end of the effect, change the values and create a new keframe ( using I again)
