Use movie scene markers in Logic Pro for Mac
Scene markers are SMPTE-locked markers: they remain at the same absolute time position, regardless of tempo changes. If you remove a movie, a dialog opens that gives you the option to remove its scene markers or leave them in the Marker track. Scene markers are identified by a clock icon.

You can use the Create Movie Scene Markers function to search the movie for significant content changes (scene cuts), and automatically generate scene markers for each of them.
You can use the scene markers as video hit points and align the tempo precisely with visual events in the movie. See Sync audio to a video hit point.
The Create Movie Scene Markers function uses a fixed threshold value, which works well for most types of movies: cartoons, real life, CGI, and so on.
