My new Gopro Hero 7 Black arrived today and after charging it and doing all the software updates I took it out on the bike to test. The resulting video footage seems to have a bad blue colour shift on the sky and sea and the greens seem to be washed out.
Recorded using 2K7 mode at 50fps with hypersmooth stabilization turned on.
I have uploaded the raw file to https://www.youtube.com/watch?v=9NNSXmOXn4w&feature=youtu.be and you can see the worst colour issues around the 5 minute mark with the sea on the right of the image.
Has anyone had this issue with previous gopro models and is there a fix or should I record in protune and fix the colours in post?

Thank you for the details that you provided, and for including a sample footage. If you have not done the software update manually, please go ahead and do so even if the camera may already have the latest update, and see if the issue will be fixed. You can find instructions below:
- Go to the Update page and choose your HERO7 camera.
- Under "Other ways to update" at the base of the page, click "Update your camera manually."
- Enter your Serial Number and other requested information, click Next Step.
- Click "Download Update."
- Click "Click here to download firmware."
- Follow the steps on the screen for detailed instructions for your operating system.
Make sure that the camera is charged to at least 50% and that the SD card that you are using is a recommended one, and is formatted prior to the manual update process. We are sending this as feedback to the team as well. Let us know how it goes on your end.

That being said, Protune will give you a better image and more control over the video results. Protune also increases the bitrate so more information will get stored in each pixel.
I don't yet own the HERO7 so I haven't been able to test out the different settings, but for previous GoPro cameras, and I assume the HERO7 as well, the following are the "Best" settings (they do require color grading in an editor):
Shutter: Auto (or manually set for the effect you want - a slower shutter allows more light and "softer" images per frame with more motion blur, a faster shutter allows less light but "crisper", more detail in each frame)
EV: -1.0 (gives the most detail in highlights)
ISO Max: 100 or as low as light allows (Gives cleanest picture with least amount of noise/grain)
WB: Manually Set to the correct kelvin temperature for your lighting (keeps colors constant)
Sharpness: Medium or Low (allows more flexibility with color/contrast grading and prevents over sharpening by the camera)
Color: Flat (retains the most color information and detail in shadows)
With Protune Off the camera is using:
Shutter: Auto (generally favoring a faster shutter)
ISO Max: 3200 (Maybe 1600 - I don't have the camera so I'm not sure)
WB: Auto (generally favoring a cooler blue color)
Color: GoPro (high saturation and vibrancy)
One last comment. If you do not plan on slowing down your footage (i.e., slow motion section of video showing a jump), then 30fps generally looks best for the type of riding that you are doing.
A manual update of the firmware is always a good idea (even if the camera updated via the App or Desktop software) so you should do this. And, of course, use a recommended SD card.
