“when i edit the speed in a clip in the timeline the rest of the clips in the timeline kinda snappes with the edited clip.”
Ok, what do you mean by “snap”? I think most of us are assuming that you mean clips are rippling to the right when you slow down a clip & rippling to the left when you speed up a clip. That’s actually the way it’s supposed to work. Slowing or speeding a clip makes it longer or shorter, FCP doesn’t adjust your in or out points to compensate. That’s your prerogative as the editor.
Personally, I just trim the clips back using the Ripple tool, or redo the edit using Fit To Fill.
