Not sure what settings you used for video resolution but your upload to youtube is only 720P. It could be still rendering as youtube is slow that way sometimes. If its only 720p then your not going to get great quality

 

I still find it humorous when someone says you're not going to be satisfied with 720p. LOL

 

The trick with YouTube and getting 4K quality uploads, try to upload with these EXACT specs:
3840 x 2160, 30fps

You can also research how by watching videos and tutorials here:
upload 4k to youtube - YouTube

I use Adobe Premiere CC 2016 and have a preset. I just import the video/sound into Premiere, then hit the preset which sets it all up for 4K Upload.

Hope this helps,

Your very over exposed also what shutter speed did you use also frame rate

 

Try to stray from auto-color balance. And get up that 4K version!

 

I would shoot 1080p50 to start with. Use Sunrise/Sunset as a fixed colour balance - make sure you are in manual not AWB mode. You will need an ND8 filter that allows 100th second shutter and ISO100. I am on the other side of the channel - Cardiff - and this works for me.

There is a very good YT video of Typhoon camera settings for the Q500 and the H by Frank someone Photography?

 

Just remembered good CGO3+ video. Episode 9 - Jeff Sibelius YouTube .

 

Much better, nice when you figure things out
