I've always manually set shutter to 1/50 when shooting video. The Panasonic GH4 allows the shooting of video in Aperture Priority mode (as did the GH3). I've never considered it to be honest, however today whilst playing around with my GH4 for the first time, I shot some footage in 24p 4K using Aperture Priority mode and I really like the results. I'd be interested to hear pro's and con's of using AP when shooting video. Some folks say not to shoot in AP because the camera changes the shutter speed - but is that a big deal? When and where would it be a big deal? It's not a problem with playback of this footage, nor what it an issue while editing. Thoughts?
I've only had my GH4 for 2 days and so far I'm super impressed with the video and photo quality. This footage is straight off the camera with no post production whatsoever other than adding the onscreen text.
