I have a clip in which I split the end of, inorder to do slow motion at the end. I did the slow motion, but now the video for the entire clip plays in slow motion in "Video Preview." The timeline says it doesn't, but the video preview shows the video in slow motion. How can I fix this?
I suggest you start a new project.
As with all effects, Slow Motion can be applied to the media, the track, the event, or the output.
Applying it anywhere else but the event may cause the effect to be applied to the whole thing.
As I said, start a new project, split the event you wish to slow down, and apply your effect only to the isolated EVENT.
