Perhaps I'm on the wrong forum but I've just started using a new camera and I've noticed a weird wavy affect in playback on some of my footage.
I thought it could be a stabilisation issue on the camera but I used a portrait lens and so I did not have the option to turn off the image stabilisation. It was a really windy day when I shot but I'm sure it can't be a wind issue because it doesn't look like it and the tripod wasn't moving.
I shot another shot indoors and the footage was fine, so it seems to have happened with some footage but not others.
This was shot on a Panasonic G6 at 1080p, 24 fps.
