We are livestreaming a 720p video feed to YouTube using OBS on OSX (iMac, probably mid-2015, from memory)
Input video is from a 1080p camera (Sony HXR-NX3), however, we're sampling at 720p due to the limitations of some other equipment in the chain.
The internet is currently a 5Mbps/5Mbps line - and I had the video bitrate set to 3500kbps, using the x264 software codec.
However, we noticed some pretty bad compression artifacts and blockiness when watching the live YouTube stream.
Today, I tried with a 4G (LTE) dongle, which had around 20 Mbps upstream bandwidth - I tried increasing the video bitrate to 9000kbps, and even 12,000kbps. However - surprisingly, we still saw pretty bad compression artifacts.
I assumed 9000kbps in video bitrate at 720p with x264 would be more that sufficient to have a live YouTube stream without noticeable blockiness, correct?
Are there some obvious things we should check first?
Or what else should I include here that would help narrow down the problem?
