Question / Help Bandwidth?

[mmob18]

Hi. I'm just wondering how much bandwidth my stream uses.
Settings:
Max Bitrate: 1000
Buffer Size: 1000
Base Resolution: 1920 x 1080
*If there are any other things you need to know, just tell me*
Thanks,

Not really sure what you mean, Bitrate is what OBS is trying to maintain an average of throughout your stream. You don't want to try 1080p with anything less than 3000 bitrate, however. You need to make sure your upload can handle that.

My upload is 2mb per second, I just need to know how much bandwidth I am using per second or hour of streaming. Just a rough estimate :P

It isn't easy to calculate because OBS uses variable bitrate by default. Let's say it's constant 1000kbps (you can use CBR in settings if you want). That means 1000 kilobits are sent each second. 1000kbps/8 = 125KiloBytes/s (because 1 byte = 8 bits). 125KB/s * 60 = 7500KB/min = about 7.32MB/min (that's because 1MB = 1024KB). 7.32MB * 60 = 439MB/h. I am not sure if my calculations are ok, but it appears if you use about 440MB with each hour.

What is CBR..?

 

[micechal]

Constant BitRate. It will make your bitrate static, which would made my calculations more reliable.

Is there a downside to using CBS? If I try to enable it, it says it's an advanced setting and I should be careful :shock:

It's generally worse quality
