I'm curious of what the approximate actual distance is in meters from you to the subject in this video? The longest lens I have for my GH5 is a 45-150mm zoom, so I see wildlife stuff happening but it's often too far off. Most of my work is done close up, so I can't justify buying a longer lens at this time. But, I do understand the issue of getting close enough. I missed a really great one last year when one day I went over to my neighbors hours to feed his cat. There were five Tundra Swans cruising down the river feeding and a Bald Eagle made a pass at them. When this began, they were about 20 meters away, then the eagle headed up river with all of the swans after it. By the time I got to my camera they were probably 200 to 300 meters away, and it was pretty much over, with the eagle wishing he hadn't done that. That would have been such a cool video if the camera had been with me instead of in my truck.
With the GH5, I only shoot in V-Log-L, and I always use the Histogram to keep the exposure as close to the middle as possible, so I don't clip either the whites or blacks. That way, I can fix most problems in post. Which is something I have had to do many times when uploading to YouTube. The problem I mentioned with Firefox appears to have been fixed in the newest version, but YouTube is inconsistent, and they know it and claim to be working on it.
For all the videos I upload to YouTube, I upload in 3840x2160, 10bit, HDR (rec2020, gamma rec.2100 ST2084), HEVC (H265 because the files are bloody large). YouTube then converts the stream using a VP9 codec, making 8 videos for HDR, one for each resolution from 144 to 4K, and another 8 for SDR. The time it takes to make these 16 streams is why "processing sometimes takes a long time before their final 4K version becomes available. You Browser then decides which stream is appropriate for your display, and different Browsers may not behave the same. Then, I do not go live until I have previewed YouTube's conversion in three or four different browsers. Too many time the quality is horrible compared to what I uploaded, so it delete that upload and and render another version that is overcompensated just for YouTube. For example, if the YouTube contrast is not correct, which is my most common complaint, I can increase the contrast in post and render a new version just for YouTube and try the upload again.
For HDR you must use 10 bit, and with HEVC (H265), I set the bit rate to 20 Mbps. With most content, 20 Mbps is good enough for 4K YouTube, but sometimes it is not. I then double the bit rate to 40 Mbps and try it again.
I know this sounds like a lot to go through to get decent quality on YouTube, but it really doesn't take very long to do, except for the first time. Once you've done it a couple times, your part is fairly fast, the wait for YouTube to "process" is slow but there's nothing you have to do, so go shoot some more footage while they are processing.
