As videographers come and go, especially those that focus more on the visuals rather than the audio aspect of production, some may not realize the importance of the sound that accompanies the visuals. It builds atmosphere, tension, and can play on many different emotions and feelings that is just not possible through visuals (hearing someone behind you for example). Remember, AUDIO is 50% of a final video or film, the other 50% is the VISUALS. Without good audio, your audiences perception of the recreated reality portrayed in the visuals becomes blurred as it is not realistic to hear naturally, think about it!
If you are working on a production where you know the quality of the audio or visuals will be compromised, then have a back up plan! I shoot all the time on my Canon 60D, DSLR's having notoriously terrible in built microphones so I overcome this in ENG situations by using a RODE Videomic, which does the job. However, for exceptionally clean and high quality audio recording an external mic+recorder device is crucial especially for talking heads! I used the Zoom H2 audio recorder to capture the sound externally, to then sync up in post.
A GREAT TIP!! If you are in a shooting situation that allows; set the camera and audio device recording and clap. This will create a spike in the audio waveform and will make it so much easier to sync up later on!
My reason for discussing; I'm currently choosing the accompanying music for the GLF conference video. I use a site called Audio Network to source most of my audio media as it has great creative commons uses and is reasonably priced too, as well as having such a vast array of production style music.
So far, to go with the up-beat and enthusiastic, youthful visuals I have chosen these two to go with the visuals; let me know what you think!
I look forward to hearing your thoughts on the music, and any similar production questions or issues you may be having!
