Bitmovin vs Cloudflare Stream

We want to make a live streaming platform demo to show off our video compression technology.

Simply put, we will stream content from 12 x 4K cameras ——> to an edge server(s) containing our compression software ——> either to Bitmovin or Wowza ——> to a media player.

What we would like to know is, is one of the above streaming engines more suited to multiple feeds (we will eventually be using more than 100 4K cameras for the actual streaming platform), 4K content streaming, latency, and functions such as being to Zoom in on the 4K content?

If anyone has any insight into the above, we would be grateful for your advice. We are a Japanese company and were recommended the above two streaming engines but know nothing about them as they literally “foreign” to us.

Thanks so much.
