Question / Help My streams are "1080p" - but they're definitely not.

[Brandon Sidebottom]

Hi!

I've been streaming a lot recently, and something I've just noticed after looking at a Youtube upload is that my streams are a really low quality even though they are labelled at 1080p.

You can see what I mean in this video here. Even at 1080p the video barely appears to be 360p.

I've copied my log for that exact stream onto this pastebin.

I use Restream.io to stream ot Twitch, Mixer and Youtube at the same time, could that be the issue?

Any help is appreciated, let me know if there's anything I've missed - thanks!

To stream 1080p without this blurry effect you will need approx. ~12MB effective upload. You have 3500. Twitch limits the upload to 6000kb/s for non-featured streamer. So my advise: scale it down to 720p@60fps. This will look much cleaner.

Edit: Expect you stream slow motion games like hearthstone or league of legends. Fast moving picture ingame are really bad with 1080p.

Thanks for the advice, I didn't know that!

Just curious, I'm on a 5K display (I'm using Bootcamp on an iMac), so my Base Canvas is set at 5120x2880, unfortunately that resolution doesn't let me scale to 1280x720 - how would my stream quality/system performance be effected if I change my base canvas to 1920x1080 and then scale to 1280x720?

Thanks for the help!

Since you play in 1920x1080 you will definitely get a better output if you set your base canvas to that. It will be easier on your system to output 720p as well, yeah. You should also try to go with a wired connection if you can, since it's a lot more stable for streaming.

There's no 4x downscale divisor (multiplier)? I can't easily test that resolution. But 720p is 1/4th of 2880p, so the math would work, instead of having to fake it by changing the base canvas size.
