One of our long-time clients asked up to film a welcome speech aimed at new employees. We created a portable set in an office with noisy AC vents and interstate 285 within viewing distance. This room was our only option so we went with it. High ambient noise can cause issues when trying to capture clean sound, even with good mikes. Our solution was to shoot the speech and then record some ambient dead space on the tape. Then we filtered out the AC unit and traffic noises in post production by isolating the sound waveforms.The film was created using a Canon 5D Mark 2.
