There are custom video controls in the code, but they are currently disabled because they're missing keyboard support. See the discussions here:

In a desktop browser, you can click the video to focus it, then play/pause with Space. While the video is paused, you can also scrub with the cursor keys. That might be an alternative for volunteers who want to examine individual frames in detail.

Similarly on a mobile device, you can play, pause and scrub with your finger. In addition, you can also pinch to zoom in on paused frames.

Some linked discussion about keyboard support for media players:

EDIT: In Firefox, the cursor keys scrub through a video in 5s steps, so that's not a useful alternative for 10s video clips. Chrome scrubs smoothly through the video clip, frame by frame.
