YouTube Visual Artifacts

YouTube turned this video into a mess with banding and/or macroblock compression artifacts which do not appear in the original video file from my Lumix DC-G9.

To illustrate, here are 2160p60 videos delivered from my Web server via HTML. Depending on your Internet access speed to my Web hosting server, you may need a lower bitrate which comes with lower visual quality. If access bandwidth is sufficient, you should get real-time streaming display of the video. My conclusion is that YouTube's compression causes the artifacts due to streaming delivery considerations.

Original G9 2160p60 at 150Mbps

Rendered at 70Mbps
This is the bitrate used to submit to YouTube.

Rendered at 35Mbps

Rendered at 20Mbps
