I didn't want to resurrect an old thread but since there was no definitive conclusion about this issue I'll open this one with additional question. 1. There is a visible wobble on my videos filming both in 4K and 1080p. You can see it on building in this video: Anyone else having those? I didn't notice it before. Day was windy, 6-10m/s. I also switched to CF reinforced props. I will try again when wind settles down. 2. When I record 4K video (haven't tried with 1080p) there is a small gap, maybe few 1/10th's of second between two joined files. Video just jumps bit forward on "stitch". Is that normal?
