image depicting the flow of a moving subject.
Select the images you want to merge in the Video Frame Capture view, then click Merge
Frames to switch to the Merge Frames view.
Important
You can merge between 5 and 30 still images.
Still images corrected in the Correct view cannot be used. The original uncorrected still

steady camera (fixed to a tripod, etc.) without zooming or adjusting focus while
recording.

When frames in which moving subjects/shadows overlap are selected
When using a video recorded in a place where moving subjects and the background
have similar colors and shapes
