Adjust Cinematic mode video clips in iMovie on iPad
When you record video in Cinematic mode on your iPhone, the Camera app creates automatic focus points for faces, animals, and objects that it recognizes. You can also tap objects while recording to create your own focus points. In iMovie, focus points created automatically by the Camera app appear as white dots; those you add manually appear as yellow dots with a ring around them. To learn more about shooting video in Cinematic mode, see the iPhone User Guide.
When you add video clips from your Photos library that were recorded using Cinematic mode, you can use iMovie to adjust the depth of field of the clips, add and remove focus points, and change the object or area in focus.
Note: If you adjust the video speed of a Cinematic clip, you can no longer edit its Cinematic effects.
