Why am I getting these weird square pixels and grain in my HERO 6 video. Its really noticable in the last 20 seconds of my example video.Its in all the clips shot with this camera regardless of settings. The clips in this example video were shot in 4k with camera in full auto settings. Day was bright but slightly overcast. Clips were trimmed in Davinci with clip assets set to full. no grading etc.
So far not super happy with anything I have filmed on this camera. What am I doing wrong

If the pixelation is coming directly from the camera and not from an editor or after uploading to YouTube or similar site, then there may be an issue with the SD card or the camera. If you are using one of these cards https://gopro.com/help/articles/block/microSD-Card-Considerations , have run a MANUAL update and are still seeing pixelation on raw unedited videos with a video player like VLC media player on a computer with decent specs, then contact the GoPro Support Team. https://gopro.com/help/ContactUs
If you are seeing this after uploading to YouTube or after editing, then the issue resides with how you are rendering the video. It could also be your computer. The Hero3+ Silver for example, records at up to 25 Mb/s while the Hero6 records a bit rate up to 78 Mb/s in HEVC, which is significantly more demanding on the computer.

First, your video isn't uploading as 4K so the bitrate is getting throttled down by YouTube. I'm not sure what's going on here, but if you rendered the video out as 4K, it should upload as 4K. Use 40 as your bitrate, CBR is fine. I generally select 4K YouTube as the output setting in Premiere (it's the last selection on the list) and then change the bitrate and check off Max Depth and Quality.
Second, the camera is having difficulty as you are moving in and out of shadow causing the highlights to get blown out. There are a few options to try for this.
1)Easiest solution: set the ev to -1 and max ISO to 100. By reducing the ev you will avoid the blowouts from the sun coming through the trees. A lower Max ISO will also help with this and will give you the best video quality. The video will be darker in shadows but you can correct in your editor as needed by bringing up the shadows.
Option #2 - Simple but not best solution (also you will need to take your gloves off): Use the Selective Light Metering option by pressing on the rear LCD until a large white box shrinks into a smaller box. Move the box to the brightest portion of your screen (at the sunlight coming through the trees), choose locked exposure and then press the check mark (if you don't press the check mark it wont save the setting). This will tell the camera to keep the exposure value the same whether you are in shadow or brightness. Negatives are the settings are lost every time the camera shuts down, and you can't control ISO/Shutter/EV. Also, your time in shadows might be a little too dark.
#3 Requires color grading in editor (In Premiere you can just add an adjustment layer): These settings generally work out best: Shutter - Auto, EV -1, ISO Max - 100, WB - Manually set (you can use Auto as well but manual is better), Sharpness - Low (increase in your editor), and Color - Flat.

These aren't the best examples as these are all just family videos and I generally don't do a lot of editing or playing with the settings when just filming for fun. When I am filming events or Real Estate for clients is when I spend the time editing and doing camera settings for the best shot. Unfortunately, I cannot share these as they do not technically belong to me.

Im running v01.60 really wish I could just get my money back. We film dialy with BlackMagic Ursa Pro and hero 4 , thought the 6 would be an improvement but I have yet to see a clip (out of nearly 300) that is usable for even youtube.
If its something Im doing wrong please advise, or do I simply have a a bad camera?

You don't want full bit rate if you are uploading to YouTube. It will actually make the video look worse as YouTube will render the video again. Try turning Protune off (if it was on), use low or medium sharpness, and export at no greater than 40 bit rate.

4k 30 fps protune is off and I dont believe sharpness is a variable with protune off, if it is its set at default since these clips were done after restore to factory defaults. Davinci was used only to edit clip length, the videos are just as pixelated watching them before running thru davinci or uploading, in fact youtube softens the harsh jagged pixels I see straight out of the camera.
I am sure the camera is capable of delivering useful footage eventualy
I tried 3 different sd cards today same results at 4k, useful footage seems to be available at 2.7k 30 fps and 24 fps and 1080 is good. I think the camera is having a hard time writing to the card at higher resolutions and frame rates.

I just rendered a video at 40kbs as reccomended and in play back its just one blurry mess as if watching video thru a piece of waxed paper. Since my harsh pixel issue exist on videos straight out of the camera I know davinci isnt the problem. I found a 43 page thread of people with the exact same problem. I believe I simply screwed up not doing enough research and then not getting a refund within the 14 day return period offered by my retailer.

Here is another example at 3 different resolutions, 4k, 2.7k and 1080 same weird grainy pixilation. I would like to know in all honesty is anyone getting any usable footage out of this camera? Im getting this same grain regardless of software used to edit video, it exist directly out of the camera. Any sugestions appreciated.
