picture styles effect anything you shoot with the camera. I've found I utilize the C1,2,3 functions on the shooting style dial. So in the menus for video I'll set up the camera to be pretty flat, with little to no sharpness, for raw I'll have a different picture style (just keep in mind for RAW that info is really just metadata that you can adjust later) and for jpeg another. You can then save your picture styles (and other settings) as a custom setting so you don't have to recall the picture style every time.
Thanks, I've been using Standard, so I guess I can mess around with some of the other ones. I use ACR on my RAW files anyway but my interval sequences are 500 frames or more so using say the Landscape preset may be helpful with clouds and such.
