AI shot detection sensitivity
The AI shot detector finds every cut in your video. The sensitivity slider controls how strict it is. If your storyboard has too few shots, raise it. Too many? Lower it.
Where is the sensitivity slider?
In the left column of the editor, near the tool buttons. It's a vertical slider running from low to high — values from 1 (lowest) to 9 (highest).
How do I change sensitivity?
- Drag the slider up to detect more shots, or down to detect fewer.
- StoryFolder re-runs detection on your video using the new threshold.
- The storyboard updates in place. Your notes are preserved on shots that still exist; new shots start blank.
When should I raise sensitivity?
- The video has subtle cuts — like match cuts within the same scene.
- A long shot has multiple internal beats you want to capture separately.
- The video uses gentle dissolves and fades that the detector glossed over.
When should I lower sensitivity?
- The video has lots of handheld camera shake mistaken for cuts.
- A shot was incorrectly split because a person walked across the frame.
- You're getting many tiny one-frame shots that don't represent real beats.
Is there a single "right" sensitivity?
No. It depends on the editing style of the source video. Modern fast-cut commercials usually want a low-to-mid sensitivity. Slow, contemplative cinema benefits from a higher sensitivity to surface subtle beats.
A reasonable workflow:
- Start at the default.
- Glance at the storyboard.
- If it feels too dense or too sparse, nudge the slider one notch at a time and re-evaluate.
What if I'd rather fix individual shots by hand?
Totally valid. Set the slider to roughly the right ballpark, then use the Split and Merge tools to clean up the few mistakes by hand. For many users, this is faster than chasing the perfect global setting.
Does changing sensitivity re-process the whole video?
It rebuilds the shot list, but it doesn't re-import or re-transcode the video. The video and thumbnail cache stay put, so re-detection is fast.
Will I lose my notes if I change sensitivity?
- Notes on shots whose boundaries don't change are preserved.
- Notes on shots that get split or merged carry along where possible (see Splitting & merging).
- If you've done extensive note-taking and don't want to risk shuffling them, work with Split / Merge instead of changing sensitivity.
