What are your HD Camera settings? 1080p? 2.7K? 4K? 30fps or 60fps?? And why??

Depends what your purpose is.

But I use 1080p 60fps all the time, because that's the standard everyone uses.

Some use 4K as well for 30FPS, or 2.7K for 60fps, but I found the file too big to work with, and I upload them on youtube @1080p anyway so it's really not that important.

But 30FPS is better for low light situations, apparently. Some cameras even automatically drop frames to handle low light (allows for more exposure), even if you set higher FPS.

Gopro Session 5:
2.7k has the highest bitrate ratio per pixel and gives a "better" picture.

YouTube:
It looks like upscaling any video to a higher resolution before uploading to YouTube gives a boost in picture quality as YouTube gives you higher bitrate for higher resolution video.

Same goes for higher framerate btw, so rendering a 30fps source to 60fps output is a bit of a youtube quality "hack", while it is not really more data from a compression point-of-view.

My best cams can only do 1080p60, haven't tried upscaling to higher resolution yet... sadly my video editor can not render to optimal "youtube codec" anyway so that's where i have most quality loss. Especially keyframes get messed up which results in terrible pixellation on certain players.

The truth is my computer cant handle what my cam can do but I have to say from a position of experience with technology and media that certain aspects of media quality are BS... I think for youtube videos if compressed properly a 720p x 120 frame rate, possibly down sampled to 60fps is going to be more than enough...

admittedly I am talking out of my ass here and I don't exactly know what I am talking about for sure but the truth is there are a lot of folks who try to make it sound like we need more pixels and greater than 60fps that are fooling themselves :p

We're at a point where we've already hit the quality roof on what needs to be output in media... 4k is just a way to sell more expensive equipment if you ask me :p

Well, i second that for the "output" ... i mean come on, how close do you want to sit to that 1080p TV to recognize a single pixel.

However, when working with raw materials (post-processing, editing etc), "more" makes sense (comparable to audio production in 24- or 32-bit and possibly higher frequency too) to help precision and reduce aliasing etc.

The problem boils down to that YouTube doesn't give you high enough bitrate for 720p videos to look good. Like mentioned earlier, the workaround is to upscale the video to a higher resolution to get the higher bitrate. It's all about bitrate and a 1080p video with low bitrate will look like crap while a 720p with high bitrate can look great. Obviously, higher bitrate is better to a certain point where you don't see much difference anymore.

You can try to upload a 720p and then upscale the 720p to 1080p and upload and you will probably see a difference

It looks like I might have to correct myself. It looks like the highest bitrate per pixel is 1080P 30fps at 45Mbit/sec.

2.7K @ 30fps protune on 60Mbit/sec

2.7K = 2704x1520 = 4110080 pixels

(60Mbit/s) / 4110080 = 0.00000146


1080p @ 30fps protune on 45Mbit/sec

1080p = 1920x1080 = 2073600 pixels

(45Mbit/s) / 2073600 = 0.0000022


as you can see, the bitrate vs pixel ratio is higher for 1080P 30fps

oops, i'll have to correct myself again... looks like 720p @ 25fps gives you the highest bitrate per pixel...

1080 50fps superview, I live in a country with ac at 220v/50hz and usually fly at night so 60fps will result in a lot of flickering coming off from the street lights.

But during editing and rendering, I will upscale the video to a higher resolution for YT.

Haven't tried that yet, what's next step after 1080p? 1440?

I use a Xiaomi Yi with superview script.
1080 60fps.
The 60fps create a nice smooth video.

For those who are using GoPro Session 5, here is my 2 cents..

yup,

but you can go all the way to 4k too. It wouldn't improve your picture, but it does retain the quality when watching on YT.

This an example of an upscaled video.

I'm not sure why I can select upto 4k if viewed in the forum but only up to 1440p if viewed on Youtube from my 1080p screen laptop.
