The main issue will be how much upload speed you have at the location(s) you'll be streaming from. Perhaps you should take this in two steps.

First add stream at 1280x720 at 2000-2500 kbps for HD viewers and keep your 480p stream at the 650 kbps bit rate for viewers with slower connections. You might want to consider a 16:9 resolution on the 480p stream.

Then if all goes well, add a third stream though I wouldn't stream 1280x720 at 1000 kbps. That's well below the YouTube recommended minimum of 1500 kbps.

Or consider a 1980x1080 stream (minimum 3000 kbps) and the lower res stream for viewers with slower connections.

Hi Pesi

yep as Tom said, you gotta change your streaming platform. I already explained this to you in one of your very first post in the forum! I told you to use a platform that handles "MultiScreen transcoding" so that with a single 1080p stream, your viewers can have automatic selection by their device between 144p, 240p 360p, 480p, 720p and for sure 1080p depending on their available bandwidth and screen resolution. Besides the platforms that do multiscreen also do ABR, e.g. Adaptive Bit Rate streaming which is very important to avoid buffering. It means that even if a viewer has variable bandwidth, his player will automatically switch to an inferior quality for a moment so that the viewing experience is not stopped (with this annoying buffering symbol). As soon as he gets more bandwidth, the player comes back to best quality as possible.

Have a good day

6000 kbit/s is recommended for 1080p
1500 kbit/s is the minimal requirement for 720p, the moving shots or the transitions effects won't be good with such a bitrate. 3500 is recommended for 720p

If your CDN can transcode, then stream a single 1080p at 8000 kbit/s and you will have TV quality
