Didn't see this mentioned anywhere else but the color space selection (sRGB/Adobe) affect AVCHD video. While the selection is under the camera menu, it does affect video: if you use sRGB you get more vibrant/saturated colors and if you select Adobe RGB, your colors will be a bit muted in the video. Not sure if this is the expected result but I've confirmed it with several videos, one of which was an IT8 target.
