A few users including me since today has experienced jello.
My description of jello is horizontal jello pudding effect scrolling from top to bottom during videorecording in almost every modus.
Most users have discussed a very broad range of reasons for this type of error / displeasement.
Wifi interference / 4G interference / power lines etc, etc but none of this is true.
I placed my Mavic on a straight surface with the props in taking-off mode but not at full speed.
Looking at my drone from the top I've spotted this fuzzy white outerline of the left front prop. It looked like it was not balanced.
Feeling the drone vibrating in a unusual way I've decided to change the left front prop with a new one and the jello was gone.
I've made a video from my drone with jello and a prop replacement during the video and the new prop...
