Question / Help How to achieve true 720p on OBS to YouTube Live Channel

GlobalFitnessClub · Dec 31, 2013

Greetings,

I just upgraded my ISP that formerly had an upload speed of 2Mbps. It is now 5Mbps.
When I stream via OBS (to YouTube Live), I seem to only achieve a max rate around 358kb/s.

I've tried various combinations of settings but can't seem to get any higher streaming rate out of OBS.
I currently have the following OBS settings (from the log file):

For YouTube Live you want to enable CBR.

Set the FPS to 30 and use a higher bitrate (1000 kbps is a bit low for 720p).

GlobalFitnessClub · Dec 31, 2013

CBR? If you meant CFR, I have that enabled already.

FPS was 20, changed it to 30
Increased the bitrate from 1000 kpps to 4000 kbps.

No change in resulting stream spead (as indicated on the lower-right hand corner of OBS). Still maxes out around 348kbps

GlobalFitnessClub · Dec 31, 2013

I found CBR. Enabled it.
Now we're talkin!!!

Getting over 4100kb/s now.

Thank you Gol D. Ace!!!

Kind of makes me question if the content you are streaming actually needs 4000 bitrate. With VBR, x264 only uses as much bitrate as it needs for a scene. Low motion/low complexity scenes don't really need that much. What are you streaming, exactly?

I mean, I guess it doesn't really matter, YouTube transcodes everything anyway.

Gol D. Ace · Dec 31, 2013

Yes CBR. (Constant Bit Rate)
CFR is Constant Frame Rate.
