h265 hevc: which option is better for optimal bitrate and quality? Test Counter-Strike in 10s slice!
Why I prefer h264 and DNxHR instead h265? How is QP 0 different from the QP 20? And QP 40 from QP 25? I recommend you to use h265 only with QP from 25 to 51. If QP=0 in h265 (hevc), you face some troubles. Just use h264 for this tasks.
In this video you can see the great difference in the smoke! You cannot look for enemy through smoke with qp=51, but you can do in with qp=30. The information content of your video depends very much on this parameter. You can compare video size and bitrate with different settings of this parameter.
I suspect YouTube is not good at handling this video format. h264 and DNxHR is better for Youtube!

In general, a detailed guide (explanation, clarification, tutorial, manual, tests, details, training, experiments) about h265 HEVC.
And how to achieve the greatest, best, highest quality for YouTube?
Simple and short, visual guide. Comparison, comparison, analysis, parsing, analytics, revealing, benefits, compression, compactness, video download, video processing, playback, perception, detection.
