I have an animated movie file playing from Blackstorm with a keyhole for video to follow in. It starts off screen comes center and then grows in size. I built 3 effects dissolve memories with the DVE in each of its three positions and built a custom control to run each in time with the video. The only problem is the DVE pops from one frame to the next it does not interpolate. Is there a setting I am missing? When each of the actual memories is recalled on the keypad the move goes smoothly from point to point like it should, just doesn't work with the custom control..
