Best GoPro Resolution for FPV (Patreon)

Dear Patrons,

In tomorrow's video (about 9 hours from now), I will show that 2k resolution from the GoPro is clearly superior to 1080 or 4k, when the subject is fast motion like FPV video. The reason for this is that the GoPro Hero 5 Session uses 60 Mbps bitrate for both 2k and 4k resolution, so (duh) video quality is significantly worse at 4k when the scene contains enough fast motion to stress the bit-rate, which FPV video does.

I'm curious what your thoughts are about this.

PS: The video for the next day is shaping up to conclude that 2k video is ALSO best for uploading to YouTube, even if the viewer only views in 1080. Interestingly, it is (tentatively) looking like uploading and viewing in 4k is NOT better than uploading in 2k and viewing at 1080. Stay tuned...

Looking forward to it. Of course 2K/60 @ 60 Mbps is impressive, would love to see/compare that to a 1080p/60 @60 Mbps. Any other cams you know of that can modify the bitrate like the Yi?

No I don't. I agree that would be a great test. Especially because most viewers are probably using 1080, 60 Mbps 1080 would surely trounce 60 Mbps 2k.

I heard there is also a difference between a native 1080p upload, and the same footage upscaled to 2k or 4k. Would be interested to hear your findings on this too. Also 60 vs 30 fps? I heard there's a bitrate impact to this one too. I think the community could use some advise on GoPro and encoder settings in general, there's some great pilots who upload at settings that turn out really ugly after the youtube encode is finished. I think the problem is often people uploading at a really high bitrate compared to the bitrate youtube uses.

If the 5 series caps at 60Mbps is there no advantage to shooting ProTune? If std 2k is using up the whole pipe at 60 then it follows that in order to write the larger files for protune at 2k it would do so by compromising quality. Maybe only advantage of ProTune is seen at 1080p/30?

Record at 1080p 60FPS SuperView and upload as 4K to Youtube. BOOM. I have two vids up on youtube. Same original footage but one is uploaded as 1080p and the other is uploaded as 4K. The one uploaded as 4K enjoys a higher BitRate. I think youtube allows a higher bitrate for 4K.

YT does use a higher bitrate for 4k but only if you also watch in 4k which many people won't. But I think you will get better results recording in 2k and uploading in either 2k or 4k at that point.

But the highest FPS I can get on 2.7K with Super View is 30FPS. And I find I get less Jello at 60FPS. Not sure why. I'm a SuperView Snob. I guess this just works for me.

I've seen this phenomenon for a while now regarding the Youtube uploading. I'm not sure why more people don't do it. Something like 1440p or higher YouTube considers Ultra HD and gives it a much higher bit-rate after upload. So using a good video editing application you scale your 1080p up a little, try not to compress it too much and then upload. Like you mentioned, watching at 1080p will still be better because the resolution and the bit-rate are separate things.

I'm not convinced that there is a benefit to uploading at higher resolution if the viewer is watching at a lower resolution though. I have done some research into what others say (not FPV pilots, mind) and they say that uploading at 2k or 4k is only beneficial if the viewer is watching at 2k or 4k.
