What is this "wavy heatwave" effect and can it be removed in post?
I took several shots on a Panasonic Lumix GX80 on 4k, at 24fps and 50 shutter speed. Most of the shots I took on a tripod have this strange distortion that looks like a heatwave on them, which is absent from the handheld shots I took. I'll attach one example.
As you can see, the shot is static, so I'm ruling out the rolling shutter problem common to many high-speed videos. The tripod was very cheap at it was a bit windy when I took the shot, so I assumed it was a problem with the camera shaking imperceptibly and an auto-stabiliser. As you can see at the beginning and end of the video, the tripod heavily shakes when I simply press the record button.
But are there other issues that may have caused this, such as the shutter speed? I found this post that seems to describe a problem similar to mine, but I all of the videos attached have expired so I'm not sure it's the same issue: https://community.adobe.com/t5/premiere-pro/wavy-4k-video/td-p/8911056?page=1
Most importantly: can I fix this on Premiere, or do I need to reshoot?
