I do things differently. I will add the necessary Effects to the Clip first, with no Keyframes yet. Then, with the Clip Selected, go to Edit Effects, which will get me to the Effects Control Panel. Then, for each Effect, will toggle animation (Stopwatch), to start adding the Keyframes, and then adjusting the parameters of each point that I want to affect the Clip. Each Effect, that can be Keyframed, will have its own set of Keyframes. They may match up with one another with several Effects, but they do not have to.
My guess was that you only added Keyframes for one Effect, and if you did this in the Timeline, it was probably either Opacity, if in the Video Track, and/or Volume, if in the Audio Track. Those Keyframes do NOT affect any other Effects.
Good luck, and hope that this helps.
PS - if you are still having issues, please post a screen-cap of the Clip Selected, the Effects Control Panel open, and the Effects twirled open.
Thanks bill that does the trick Tom
Excellent! So glad to hear it, when a plan comes together.
Happy editing, and thank you for reporting.
