Guys, I've experimented with the rotate effect on a transparent image. Though I've read the section on keyframing a couple of times now, I must be doing something wrong, because the interpolation between the two rotate effects that I have applied to the video track is not happening. I especially read the part where it says: "Effects are only key-framable in automatic mode because of the number of parameters in each individual effect"
Here is what I am doing: 1) the transparent gif is stretched to 120 frames on a video track 2) I apply a rotate effect on the first five frames of the track 3) I apply a rotate effect on the last five frames of the track 4) I turn on automatic keyframing by selecting the key icon on the command bar of the timeline 5) I set the rotate parameter on the first applied rotate effect to 0 degrees 6) I set the rotate parameter on the second applied rotate effect to 180 degrees 7) I hit play to watch 8) I then render out the final to confirm what I am seeing. And what I am seeing is that the interpolation does not happen and the image rotates only when the insertion point hits the second rotate effect. Here is what my timeline looks like: http://content.serveftp.net/video/rotateapart.png Here is a sample of the rotate param tweak: http://content.serveftp.net/video/rotateparam.png I've also tried applying the first rotate effects to the first and last halves of the video so that they are adjacent to each other (http://content.serveftp.net/video/rotatetogether.png) I then turn on auto keyframing and make my param changes as before. Unfortunately, this yields the same result. Hopefully, someone with more experience with auto keyframing with effects can help me out. thanks, scott -------------- Original message ---------------------- From: Andraž Tori <[EMAIL PROTECTED]> > i really tried to be as polite as possible :) > > anyway, have fun with new discoveries :) > > bye > andraz > > On Wed, 2007-04-04 at 15:59 +0000, [EMAIL PROTECTED] wrote: > > Ayyy!
