Hi Kent, I don’t have Movie Studio Platinum 8, but if it’s anything like Vegas, it sounds like you have inadvertently created keyframes. Open up the effect in question, are there little diamond shapes at the bottom of that window, in various places on the mini timeline? If so, then you’ve created keyframes. If you want the effect to be constant, ie. not morphing over time, you have to go to the frame where you like the effect, and copy that diamond to the very first diamond in that window and delete all other keyframes. If you follow what I mean? If you want the effect to be at a certain frame and onwards, you’ll have to slice the video at that point, to the point where you want the effect to end. Or keyframe in the action “Reset to None”. Both accomplish the same task. Not all effects have the “Reset to None” option though. Like I said, I’m not certain this applies to Movie Studio, if it doesn’t, disregard this. But this sounds like what’s going on, in your situation. Hope it helps?
