Chad Perkins: A common problem for many video cameras, including DSLRs, is that of moire. This is a really interesting, but also really ugly visual phenomenon that creates weird patterns and jagged lines like this. This problem, caused by the camera's sensor, is most obvious when filming things with fine details. Stripes on people's shirts are one of the most common causes of this, but anything from the pattern on a distant building to patterns in fabrics, can cause it as well.
DSLRs just have a hard-time resolving these details. There are filters for your camera that you can purchase that reduce or even eliminate moire, such as the VAF-5D2 filter. We haven't tested them and they are kind of pricey, but that option is there. Let's be clear; moire is an abomination. And once your footage is captured with it, there's nothing you could do to fix it. So do whatever you got to do to avoid it. If you have to, talk to the producer or director about wardrobe choices and let them know of the potential problems. Moire is certainly something that should be given forethought and avoided at all costs.
