There are two crucial components to any video: audio and visuals. On production day, you want to make sure both are meeting your standards. You’ll want to test all your equipment and work with an experienced producer to get the best sound and picture possible. You’ll want to check all the sound equipment (mics, booms, and more), as well as all your camera equipment. If you’re on set, make sure your shots match your storyboard and your brand style. If you’re not on set, ask for photos or video chat for a few minutes to make sure your video is coming together as it should.
Here's where the final lesson of composition comes in: continuity. Continuity is the process of combining shots into a sequence so that they appear to have happened at the same time and place. A key part of continuity is making sure any ancillary objects in the scene — for example, a cup of water on a desk — stay in the same place (and have the same amount of water) throughout all of the shots.
