Your iPhone might do a great job of focusing on the subject when you take photos, but when it comes to video the camera will continue adjusting and re-adjusting as you move around the scene. To solve this problem, lock the exposure before you press record. Hold your finger down on the subject of the video until a yellow box appears with the words “AE/AF Lock”.
Just as important as your visual effects are your audio effects. Sound mixing, dialogue, narration, and music all come together to create the audio that’s heard when your video is watched. Even just adding a layer of ambient sound over a quiet scene can make the difference between what feels like a high-quality video and a low-quality one. Make sure a professional handles your audio mixing, so you have the perfect sound levels, foley effects, dialogue volume, and more.
When it comes time to shoot, clear out unnecessary people from the room and turn off the overhead lights. With your three-point lighting setup, there will be no need for those harsh fluorescents. When — and only when — everything is set up, call in your talent. There's nothing worse than being nervous, and then having to anxiously watch as lights are turned on and the camera is tested.
