How to have the best possible picture streaming a slow pan

Assuming bandwidth and processor/GPU's are not a limiting factor:

Does anyone know what video/stream configuration settings will offer the best possible stream quality for streaming a video that is doing a slow pan of the scenery to youtube? I want to have a clear picture constantly and not have it refresh the image every 2 seconds or whatever my current settings (keystone?) is causing it to do.

My computer specs are: Dell G5 5000,nvidia GTX 1660 Super, Intel i5-10400F, 8GB RAM, 512GB SSD

Thanks!
 
In technical terms even slow panning footage means a total (big) difference in content from frame to frame, resulting in high demand on bandwith. So your question relates to a spinning forward broadcast quality. The only thing that helps is high bandwith in streaming. So keep at 1080p30 and stream with more than 6 mbps (if you can and your provider allows) to get the most frame-to-frame quality out for each of the 30 frames. (If you planned to go 1080p60 or something, remember: The bandwith has to be shared for all optical differences from frame to frame, so dividing by 30 leaves more room per frame than dividing by 60...)

Regarding the 2-seconds thing: Do you mean the fullframe-rate? That does only mean that every two seconds a full frame is sent, all frames in-between are differential-encoded. If you now think, that you better go with a full-frame every 1/30 second ;) you should know that these are "all-intra" codecs demanding bandwith at 100 or even 200 mbps. With todays technology this is not possible for internet-transmission and providers like youtube. Rather than, if you use full-frame every fourth second (not more!), the more bandwidth will remain to differential-encoding in-between frames...!

Play with the knobs what will work best for you! :)
 
Regarding NVENC you should go and try settings like "Lookahead" and "Psycho Visual Tuning" with 2 B-Frames (your GTX 1660 Super should provide this, if i'm right).

The rest depends on the software which does the panning job. If it provides "smoothing" or "smearing" effects, try different settings, please. Smearing does provide a smoothed look in motion for the human eye, but can result in a harmful desaster for the H264-encoder behind, because he sees blur from frame to frame, difficult to encode. Playing with different settings you should judge on the final outcome, what comes back from yt to the viewer.
