how to continuously rotate an image in the video editor I'm trying to make a very simple video of an image being continuously rotated, but the 2.6 manual on this seems to be outdated. In 2.70 there is no rotation start/end but just a constant angle. Could someone share how this is done in current versions?

not sure if this needs to be clarified but i'm importing the image in VSE as a strip (Shift-A -> Image), not splashing it on a plane and trying to capture that with the camera ... or something else
You add a transform effect strip then keyframe the start and end with rotation changes. Otherwise you can add a couple small rotation keyframes to check speed then add a Cycle modifier to the f-curve of the .blend that extends the animation out past the keyframes.

  Cycles mode - Repeat with Offset
  : Repeats the curve data, but offsets the value of the first point to the value of the last point each cycle.
