Last weekend I did sound for a commercial which is part of the Crash The Super Bowl contest. We shot 2 commercials, and turned them into 8 different cuts for the contest. Top 5 wins big money, grand prize airs during the Super Bowl on top of that.
A few of our locations were real bad for sound, so we really needed some of those processes and effects too. Our first location was at Stop & Shop down the road from me. They were nice enough to turn off the music but the sound of the coolers in the produce section we were shooting in was terrible. A hum. A loud loud hum, from every section. They cant turn that off or their food may go bad. So we had to deal with it. Moving the action away from the worst parts and pointing the side of the boom towards the sound (pointing the tip parellel and away) was the best way to go. However, the hum is a low frequency and voice is also low frequency, making it very difficult to get rid of the hum in post. Fortunately our shots were pretty tight and the only person with dialogue there was a woman (higher frequency voice than male). So I was able to improve it in post for sure, but listening to it with headphones, especially next to good audio if no room tone, it still was rough.
Although I did have some easier locations (and some other difficult outdoor ones) I did create some portfolio worthy soundbites. I'll post when I post. But LIKE us on facebook and if we get into the top 5, vote for us!
