General rule of thumb for 1080p video streaming = 8 Mbps
720p is half the size, so it should be half that rate = 4 Mbps.
I have no doubt that modern image compression algorithms can bring that down a bit further without too much impact on quality.
So with a median of 7.2 Mbps, that's probably enough for 2 users to have an acceptable video conferencing experience. But if that's the median, then half of their customers have a lower upload speed than that and may only be able to get away with a single user streaming at a time.
- estebank 4y ago720p isn't half 1080p, it's a quarter because you're halving resolution on both axes.
- austinprete 4y ago1080p is 1920x1080 ~= 2.1m pixels versus 1280x720 = 921,600 . So a little less than half but definitely not a quarter. And neither dimension is actually halved.
- estebank 4y ago:facepalm: I rushed to be wrong by not mentaly checking that 720 is indeed half 1080. Resolutions indeed never doubled from one step to the next.

I had a 15/1 connection for a while and found no issues with Zoom calls. Maybe an issue if you’re a professional cammer though. I mostly work on CRUD virtualized apps (effectively screenshares) all workday long and will use well under 1gb in a day. My biggest beef with Zoom and the like is being unable to restrict resolution/camera quality of myself and others (other than setting the others into small sizes). I’m in Canada where mobile data is expensive, and therefore very fast. The provider is happy for you to chew your handful of gb per month at full speed and then you top-up with more or get hit with overages.
