Hi everyone.
I am running a video signal via HDMI from a Sony DSLR camera to an AverMedia GC311 Live Gamer Mini and then into OBS.
The camera outputs 1080p at 50fps and the GC311 can also output at 1080p, 50fps or (for example) 720p at 50fps.
I am live streaming talking head type stuff (with very little movement) to YouTube.
Now according to YouTube's own specifications for maximum bit-rate at a given resolution, I can either stream at 1080p, 25fps at maximum 6000kbps or 720p, 25fps at maximum 4000kbps.
According to the calculations that can be worked out here: https://www.chow-bryant.com/service...ing/live-streaming/live-streaming-calculator/
a 1080p, 25fps stream requires minimum 5184kbps so if I give it 6000kbps this represents a 16% increase in bit-rate over what is needed.
A 720p, 25fps stream requires minimum 2304kbps so if I gave it 4000kbps this represents a 74% increase over what is needed.
So I have two (2) questions:-
1) Given the above calculations is it better to stream at 720p, 25fps up to the maximum bit-rate of 4000kbps for visual quality (in theory more so than practice as I realise it's very hard to actually spot the difference)?
2) If yes to above question, then should the down-scaling be done in the Live Gamer Mini or in OBS (again in theory rather than practice)?
Thanks for reading this long post and thank-you for any wisdom or insights you are able to share.
