    Hello, I have read somewhere (I don´t find it now) that Gopro Hero 4 has some options like keeping ISO constant, and it has faster processor , that would reduce jello effect. Do you know something about that?

    Thanks!

    Thanks dptcalvin. But I don´t find a conclusion. While ianwood says that GoPro 4 has faster imager and jello has to be decreased, outtahere finds problems, after adjusting gains (it improves, but still has a litlle jello in his last video), using ND filter...

    Does someone more have a GoPro 4 ? do you have jello?

    I´m considering to buy one but I´m not sure if the cost is worth of it, I have already a Gopro 3 Black.

    Thanks!

    I have a Phantom 2 Vision Plus tha has been converted to H3-3D with GoPro 4 Silver.
    Personally I balance my own props (I even have a set of Chinese 9450 that were extremely unbalanced) and I get no noticeable jello on my videos. I use the white damper balls that came with the H3-3D and 2 of the retaining clips installed diagonally.

    I hope this helps, TuT

    That was my point. The 4 does not solve the Jello problem.

    I have been using a GP 4 with soft (black) gimbal cushions, cold temp flights in winter lighting (both sun and cloudy). I have had no jello issues at all but am always filming at 60 fps (1080P or 2.7K) . I am not sure that just shutter speed is making the difference - It seems to be combination of the vibration transmission, frame rate and lighting that affected my Vision + when I used the standard camera. I replaced that camera with the Quickrelease plate and the GP 4 on a Zenmuse gimbal and my jello problems disappeared. I also have my gains turned up in DJI Assistant software which apparently is important to reduce vibrations (which I did notice when I turned them down once).

    Hello Telemark:
    - I also film at 60 fps (1920 x 1080)
    - I have my gains at
    Basic: 120 120 120 200
    Attitude: 220 220

    -I think the temperature is determinant. I have noticed that in hotter days (in the summer for example) there is more jello. What colour of dampeners is recommended in a hotter day?

    Thanks!

    All CMOS cameras can exhibit rolling shutter effects (jello). The Hero 4 has a faster imager than the Hero 3 and therefore will be less prone to it happening. But if your motors/props aren't balanced, your gimbal dampeners aren't tuned, your gains are all messed up, and/or you shoot in bright light with no ND, you will get it.

    BTW, the gains suggested in that other thread are crap.
