No I don't think he induced jello, I think either the P3 camera or more likely his post production software put in too much contrast. If you look at the mountains in the distance (looking over the roads) the front side is all darkened out.Do you mean you think he introduced the jello effect in post?
maybe an nd filter will be required.
Maybe we can get an answer from the source...
"Mr Bloom Sir
A video that was said to be yoursHas some questionable quality from the DJI Phantom 3.
Could you do a brief explanation of the shoot?
And verify for those looking and trashing DJI if in fact it was your video. I would assume you have a DJI P3 yet no examples are within your channel.
Thank you if you could help clear this up."
