In video editing, trimming a video is the primary task, which is sometimes difficult and time-consuming. Smart Trim auto-extracts best scenes based on attributes such as people (single or multiple), action, and the quality of the scenes.
If you would like to modify the auto-extracted results, you can change the slider position to add more or less scenes. You can further modify the results by manually adding, deleting, or changing the duration of individual scenes. When you are happy with the modification, preview and export the trimmed clip to the sceneline.
