I'd like to write an 'effect' that would pan the frame, to be used like the effect 'Zoom In' that can be placed on the Fx track and so apply to a sequence of clips and images. This would be more useful to me when assembling screengrab clips than having to edit keyframe positions and zooms for each one.
I'm fairly happy with programming in C etc, I just need to know what I'm programming against, eg APIs and how to install new effects.
Can anyone point me at suitable documentation? Google and duckduck fail me, but then I seem to have great difficulty finding solid docs for powerdirector "-(
Thanks
Martin
