I haven't seen too many people talking abou this issue but for me this is what is preventing me from using my OSMO commercially. I work in video production for television broadcast/corporate clients and I'm struggling to get footage that is passable due to the image degrading with both colour banding and macroblocking during scenes with a lot of detail. So far the only thing I can do to mitigate this is to avoid shooting in 4K (boo!) and shoot in 1080 60p or 48p to keep the bitrate up.
I wish DJI would enable a pro mode that allows for some type of ALL-I compression with a constant bitrate. Not sure if this even possible with the sensor/image processor. If it's a matter of heat then I'd even be fine with the fan being cranked as I'm either not using the sound or it's being recorded seperately. My Sony Action (AS100V) cam has a 50mbit xavc mode that produces pretty amazing video, it is also using a 1/2.3" Exmor sensor.
Here are some screenshots from VLC highlighting the banding I'm seeing, unfortunately due to the 1000k attachement size I had to just crop into the frame. This footage is of me walking between rows of wheat, as soon as I move out of the row the banding in the sky drops and is fine again because there are less fast changing regions. The banding is absolutely terrible on the 4k shot and somewhat servicable at 1080 60p but there is still so much macroblocking that I couldn't show this to a client.
I'm wondering if either I have a bad camera or if this is a known issue, if it's the latter does anyone have any tips? Just FYI I've still experienced this with d-log footage with sharpness, saturation, contrast all set to -2.
