Cinemagraph

Cinemagraphs are still photographs in which a minor and repeated movement occurs, forming a video clip.

A variation is a video snapshot (clip composed like a still photo, but instead of a shutter release it is captured using the video recording function with its audio track and perhaps showing minor movement such as the subject's eye blinks).

Another variation is an audio snapshot (still photo linked to an audio file created at the moment of photo capture by certain cameras that offer this proprietary function).

[1] Cinemagraphs are made by taking a series of photographs or a video recording, and, using image editing software, compositing the photographs or the video frames into a seamless loop of sequential frames.

[2][3] The first cinemagraph was recorded in 2011 when two photographers – Kevin Burg and Jamie Beck – put some movement into a photograph of model Coco Rocha for fashion photography for New York Fashion Week.
