Preparing Media using Scene Cut Detection

Your final video project in this book involves a single self-contained video file. Placing the video file directly into a timeline in DaVinci Resolve 15 would result in it being treated as one clip with all grading changes affecting it uniformly. To avoid this, you first need to place cuts throughout the timeline to separate the individual shots and allow for content-specific grading. Doing this manually is time-consuming detail work.


Fortunately, the scene cut detection feature in Resolve performs the heavy lifting for you. It can analyze edited video files prior to import to break up their content into subclips and allow for clip-by-clip grading.


  1. In Media Page find you video on browser panel

  2. Right Click on it --> Scene Cut Detection

Follow the step above you will see the Scene Detect window appears.



You will use this interface to run the edit analysis and import the resulting subclips. At the top of the window are three viewers that display the current frame (middle); the previous frame (left), and the following frame(right).


Below the viewers, the Scene Detect graph displays the location of the video’s cut points after the analysis. To the right, the cut list identifies the cuts and

their timecodes.


  • In the lower-left corner of the window, click Auto Scene Detect. As the analysis is run, the assumed edit points are marked with green lines in the Scene Detect graph and their timecodes are recorded in the cut list.




TIP The height of the green cut lines indicates Resolve’s level of confidence that a cut was correctly identified in that location. Cuts that fall under the magenta confidence line are omitted from the cut list and appear gray on the graph. If the video has many jump cuts and whip pans, the scene detection might place many cuts beneath this confidence line. To allow for less confident cuts to be included in the final cut list, drag down the magenta line until the edit lines turn green.


  • To review the edits, scrub through the timeline by dragging the orange playhead, or click inside the cut list, and press the Up and Down arrow keys to navigate and verify the cut points.


TIP You can also use keyboard shortcuts P (previous) and N (next) to jump

between cut points.


A correctly identified cut will display a unique image in the left viewer, followed by two similar images in the next two viewers.


When you done checking all the image and make sure it correct you just click the button " Add to media pool".


All sub-clip will add directly on your media pool. you just select it all and create the timeline by using selected clip and than you can start to do the color grad.
