Video uploaded in 1080p HD. Tarantula X6 quadcopter with custom mount made out of Velcro and zip ties for my SJCAM M10 wifi. Using Neutral Density filter (ND9) lens cover to get rid of any "Jello". It was an overcast day 1 sheet ND9 (3 Stops) works great. On a sunny (very bright) day I had to double up 2 sheets of ND9 (6 Stops) to remove all the "jello".Removed FAKE transmitter antenna and stuck the REAL antenna through the top hole.
After a few more tests, the right combination for a clear sunny day requires 1 sheet ND9 (3 stops) and 1 sheet of ND6 (2 stops) for a total of 5 stops. Good balance between reducing light without stripping out the color. You can never remove ALL the jello with just vibration reduction. ND (neutral density) sheets are definitely the "jello" killer for my SJCAM M10 (1080p 30 fps).
