Ghost animations?

[Ponyboy]

i made an animation of a camera moving through a window and a light moving the windows shadow. when i exported the video, there were no issues.

but when i moved the camera to a different position and deleted all of its key frames, there are random points in the timeline where the camera will move on its own.

no keyframes, no lines showing any manual change to the cameras position. the light is doing the same thing as well. it moves on its own with no keyframes or commands to do so. like ghost. i cant find a way to fix this and i cant find this problem from other people.

any help would be appreciated.

Go to the Motion Editor, select all time, and use the Playhead preset.

It's the preset labelled "Playhead". Back to the official tutorials with you. They cover it.
