Final answer:
To create an animation that bounces on items in a video, you can use the frame-by-frame animation method and align the frames of the animation with the corresponding frames of the video.
Step-by-step explanation:
In order to create an animation that looks as if it bounces on items in a video, you can use the frame-by-frame animation method. This method involves creating individual frames of the animation and then playing them in succession to give the illusion of motion. To match the animation with the video, you would need to align the frames of the animation with the corresponding frames of the video. This can be done by syncing the timing and movements of the animation with the actions in the video.
