    Hey mate, love your vids. Also just upgraded from the Hero 8 to the Osmo Action 4 and whilst I love the camera, I've just come back to watch some of my recordings and I have that same stutter-blur on hits and glitching/ghosting in dark spots. Ironically filmed at the Golfie too lol.
    Is the fix -2 Noise Reduction, Auto 1/200, Auto EV -0.3 and 100-12800? I don't really want that grainyness in the woods and don't mind if it gets dark in the woods... Just want that blur and glitching to disappear. Sorry it just wasn't too clear from the video. Thank you for your help!
    btw ever ridden Penmanshiel?

      I've set:
      -2 Noise Reduction
      -1 Sharpness (can touch up in davinci after)
      -0.7 EV
      1/100~1/8000 SS
      100~3200 ISO
      Auto white balance
      Overall still super impressed with the camera. Much much better than GoPros offerings, the 155° sensor captures depth/steepness much better and just captures a much more realistic image overall... Thanks for the video, Alex! Weekend at Dyfi coming up and can't wait to see the outcome :)

      haha, once you see the stutter blur you cant unsee it! yea its overall a much better camera, the colour balance is signifcantly better, I always found the gopro turns the ground and trees brown and i couldnt get rid of it. Osmo the colours are like real life. I reccomend using voice start/stop it works really well, and the button is almost useless lol
      From what ive worked out the ghosting is the noise filter. -2 is the only setting it doesnt have the filter running, so its the only setting that doesnt ghost. THe noise only happens when the ISO is high (when its dark) so having it on -2 doesnt affect any vids except the really dark stuff. I find the filter smears the image too, reducing clarity, so il be keeping i off even in bright conditions.
      From my understanding for the grain you need to limit the MAX ISO : the higher it is the more grain..but the better it sees in darkness. from the vid you can see even 6400 max still has grain, so maby experiment with lower max setting like 3200 yes. My vid from NYNY, it will have been on 12800, hence the grain, but, ive never seen a vid in that darkness thats actually watchable, because gopro just looses stablisation and the whole image moves, the DJI actually has solid stabilisation still.
      Shutter speed, ( I cant test this at the mo, broken wrist, but mabye even try 1/400 rather than 1/100 minimum) the microblur on hits would be caused by the camera moving before the whole pic is taken, so speeding up the min shtter speed should reduce this further.

      Hope the wrist heals fast and looking forward to your next clips 🫡
