The present disclosure describes techniques for generating content based on rhythm. The techniques comprises acquiring a plurality of images comprising an object with movements in the plurality of images; determining whether at least one portion of the at least one part of the object in a first image aligns with a target image overlaid on the first image and whether the at least one portion aligns with the target image at a time proximate to a first rhythmic point of a playback of a selected piece of music; segmenting the at least one part of the object from the first image in response to determining that the at least one portion aligns with the target image at the time proximate to the first rhythmic point of the playback of the selected piece of music; and generating a first overlay based on the at least one part of the object.
