It shows the main controls, including the play-pause button, timeline navigation for moving forward or backward (for example, negative five and five seconds), and start and end controls, along with matching keyboard shortcuts. The reviewer uses the instructions tab to identify issues like off task and visibility issues, then marks in and plays or fast-forwards to find the start of useful work before marking out the irrelevant segments. It also demonstrates using the frame stepper (square brackets) to precisely mark an off-task portion just before the worker grabs a sponge, then marks out additional off-task walking segments.
