Looking closely at some video taken in 16:9 mode with a Sony Digital8 Camcorder, I notice this subtle banding that's apparently under certain conditions. Has anyone else experienced this? It's hard to show, it shows up more clearly when playing the raw file or a DVD but the video formats suitable for uploading tend to mask it. Here are a couple of screen shots where the effect is visible if you look closely. Two shots, one with arrows to point out an example of where it's showing up.
