In the third and final episode in our series dedicated to helping DSLR shooters improve the audio quality of their video productions, we take a look at some dual-system solutions. “Dual systems” means we use an entirely separate device to record our audio.
One basic way to improve the sound quality of a video camera is to utilize an external, on-camera microphone. The microphone that’s built into your camera is typically of low quality and usually picks up lots of handling noise. An external microphone can provide better overall sound quality.
It’s easy for sound people to burn through piles of disposable batteries on a typical production day. Wireless microphone systems tend to eat up battery life very quickly, but portable field mixers, portable digital recorders, camera hops and IFB systems all require lots of juice too.
Full Raster High Definition Video has six times the number of pixels as SD video. Theoretically it should take up six times as much space as SD. However, AVCHD has a slightly lower bitrate (24 Mb/s) than the DV codec used on most of the SD tape cameras of yore (25 Mb/s).
