PLEASE HELP! LIVE STREAM SETTINGS..

[notaverageguy]

Hello. I am working with my local kart club and im trying to live stream their races. I have over 20 mbps usually and I have canon g70 cameras that run into a stem back magic mini which goes into the MacBook Air with a m2 processor. Our live stream comes out poor every time. It looks good from the mini and from the MacBook but looks bad when we watch it on YouTube live. Im using the h264 encoder hardware at 4500 kpbs. we tried 9000 kpbs but it was so bad. you couldn't see anything.. when I run obs it say 4500 kpbs usually and drops to 2000 then some times 9000 not often tho, any help would be appreciated. Im sure I have something wrong.

Include a log file if you have a problem: here's how

To upload a log file, go to the Help menu -> Log Files -> Upload current/last log file. The current log file is for the currently active running session. The last log file is for the last time you ran the program. We recommend always including it just in case.

How would you describe the end result that you can watch on YT?

First thought would be that you have a bandwidth problem.
When you mention that you have a 20Mbps connection, is that downstream or upstream?
Remember that the critical bandwidth for streaming is the upstream speed, if you're on an asymmetrical connection.

Also, when streaming fast-paced sports, it is a good idea to use a higher framerate (ie. 50/60 fps).
This will effectively almost double the bandwidth needed to maintain expected output quality.

Is your connection to your accessible bandwidth via wifi or ethernet?
In my experience, once you introduce wifi in a streaming environment, you're begging for trouble.
Always use cabled networking whenever possible.

I'm regularly streaming full day (6-7 hours) productions from a location with a massive connection available (~500Mbps upstream speed).
At that location I'm streaming in full HD (1080P)/25fps @ 6500kbit/s. It's rare to see any lost frames.

The other day I was forced to stream a one hour production using wifi (~20Mbps upstream measurement using Speedtest app).
Initial setup was FHD/25fps @ 5000kbit/s, but the connection was nowhere near stable. Ended up throttling down to 720P/25fps @ 3500kbit/s before the stream was stable without lost frames.
