#LazyWeb question (answer *probably* related to #FFMPEG or #ImageMagick, but I guess more generally a question about #VideoEditing):

I have an image that is 18944 x 1024, and I would like to turn it into a video that is 576 x 1024, panning across the image *at a non-uniform rate*. If I have a list of "keyframe" time/X-coordinate pairs, what's the easiest way to generate this video?
