final cut pro

You can quickly break a long clip into segments by activating auto-detect clip scenes. By using this feature, Final Cut Pro will automatically determine when a divide occurs in your video, (such as when you stopped and started the camera for a scene change), and create a new clip for each different scene.

To use this feature, double click on a clip in the Browser so it appears in the Viewer.

Then in to the Final Cut Pro Menu at the top click on:

Mark...DV Start/Stop Detect

Final Cut will then place markers on the clip wherever a scene change occurs. And you will see sub clips appear beneath the file for the main clip in the Browser, with each sub clip representing a different scene or segment in the master clip.

At this point you might want to create another bin and drag and drop the clip segments into that bin. That will make copies of the segments that you then can drag into your timeline, while also leaving the main clip and the original copies of the segments in the original bin.
