On this video by the basic filmmaker gives several useful tips for shooting videos (especially interviews or talking heads type videos).
By doing a few pretty simple things when you shoot (or edit) you can improve the quality of your videos considerably as well as cover potential mistakes.
Shooting b-roll (and lots of it) is a good place to start – if your talent is talking about a product take some shot of it. Have him or her hold it in the hand and look at it – taking a shot from a different angle, with a different focal length or even at a different location or background can make the video more interesting (but try not to overdo it to keep things consistent).
If you have two cameras you can shoot the first a little bit wider and the second one together (using a telephoto lens), however with a lot of today’s high-quality cameras (and yes 4K will be better in this respect) you can also crop in post. What you can’t create in post is a different angle – so if you do have two cameras we suggest to actually use them from two different angles and not just two focal lengths.
