Video frame loupes are presented that provide a frame-by-frame video navigation tool. A video frame loupe is a graphical user interface (UI) element that may be displayed over a portion of a display screen, and which may be used by a user to navigate frames of a video clip. For example, a user may provider a user input to activate the video frame loupe to be displayed as a preview window that presents a continuum of frames available at the time corresponding to a point at which the video frame loupe UI was invoked. The user may then navigate forward/backward with frame-level accuracy.
