1
Choose the moment
Watch the original clip and decide what a viewer should see first and last. Note the action you must preserve. For a skateboard clip, that might mean keeping both the approach and the landing while removing the pause before the attempt begins.
2
Make one clear change
Trim an unwanted opening or ending, then play across each new cut. If you add text or adjust the look, do it after the timing feels right. A title cannot rescue a cut that removes the context needed to understand the action.
3
Review the whole result
Watch the edited clip at normal speed with sound on. Check that speech is not cut off, text remains readable, and the last frame does not end abruptly. Inspect the actual output file before deleting your original footage.
