You can use whatever video gear you have to share experiences and expand relationships, but it's best to use it in such a way that it makes it easy for your audience to receive the information you are giving. What you should be aiming toward is helping the viewer get involved and continue listening to your message.
For example, if you use a cell phone or camera (using the built in microphone) to make a video, one thing to keep in mind is that the microphone is only able to clearly pickup what is loudest, closest to it. In order to get audio that easy to listen to, there are a few basic things you should be doing.
Find the quietest place possible to record and get very close to the person who is talking. If there is any other sound in the environment it will be distracting and can make it very hard to understand what is being said.
Remember that many of the people who are going to view your video are most likely not willing to work hard to get your message. Make it easy for them to hear it and they’ll thank you with their time and attention.
