Ok after trying different cables , refreshing firmware in both rc and AC changing mobile devices etc finally I found that it is doing it only when it is set to 30 FPS , if it is set to 25 or 24 FPS the problem is gone....
Check out my post..... Almost the same thing as you.....
Watch this video (link to my YouTube video) https://youtu.be/2lcbeJeTqik
It's from my Mavic Air cache. Any idea what the “wave” scanning might be? Seems to only occur when viewing trees like this or something with a lot of motion. Also occurs when drone is stationary on the ground and pointed at trees, something moving, etc. It is NOT visible in the recording on the SD card in the drone itself. Only in the live and cached video. Is this normal??
Thanks!
