Lighting, lighting, lighting. Oh and camera placement. Oh and blocking!!
With vlog style shots, the talent is usually staying in one place. Make the image please. Give the shot depth. Don’t place them in front of a wall.
Camera placement. Yeah it’s standard vlog style, but since it’s found footage, we should be able to see stuff that the “vlogger” did not intend. The camera falls but keeps rolling. Or they go to turn it off, but it stays on by accident.
Blocking: Since the camera is staying still, have the talent move. Be decisive about when the talent is in a medium shot and when they lean in close creating a close up.
