As a lens focuses closer, many optical designs shift internally in ways that alter the effective focal length — the image either zooms in or pulls back as focus changes. For still photography, this is invisible. For video, where focus pulls are a standard part of camera movement, breathing is a visible artefact that marks the moment the operator changed focus.
