Question / Help Streaming Settings

[wallop]

Hello guys,

I tought about starting streaming again and I see that OBS has a lot of new features now with the recent updates, that's a great thing!

But in my case, I got lost in the settings and I'm not sure what I should use and how to scale this because I have several issues with resolution scaling and achieving 60 FPS. Anyhow, here are my relevant pc specs and upload speeds. I wish to stream on twitch and I have in mind to stream at 720p or higher at 60 FPS ( the scaling within obs is weird because the resolution on my main monitor is 2560x1440 and it won't let me downscale to 1080p, only 720p and some other stuff ) ( Dota 2, BF 4, Hearthstone, for now )

i7 Ivy clocked at 4.5 ghz.
GTX 670 2gb.
16 gb ram.

I get the lowest MS on the Frankfurt server for twitch so I did a speedtest on it.



Thanks for the help guys!

It would probably be better to post a log (with code tags so you can analyze the file). With a log we can see where you're really lacking and if anything could use tweaking.

Also, can you please change your forum avatar...

Here's the code file, not sure why it shows my cpu speed at 3500. it's at 4.2 now.
Okay, i will change the avatar :P

[Lain]

Your log output seems great - could you tell me specifically what issues you have? If anything, you might want to try 3000 bitrate if you have the bandwidth for it. 2250 is a bit low for 720p 60fps.

 

[wallop]

Well, sometimes I don't get 60 fps on the stream unless I duplicate the frames and the image is not so clear at times when a lot of action is going on, is this a bandwidth issue?

 

[Lain]

Well that particular log seems fine, perhaps it's a flash decoding issue? Could you see if you have the same thing happen when you output to file?

 

[wallop]

It seems to be fine now, the only exception is that the text is not that readable cause the downsampling of the image from 1440p to 720p is too much I think, any way I could do a workaround on this? I can't even select 1080p, only 960 or something. or all the way down to 720p.

 

[Sapiens]

Just set your base resolution to the resolution you want, then select your source and press Ctrl+F to fit it to the new scene size. However if you plan to stream at resolutions higher than 720p please consider doing so at 30 FPS rather than 60. Flash handles high resolution+high frame rate streams poorly, they're much more demanding to encode, and they tend to look poor anyway due to Twitch's bandwidth restrictions.

 

[wallop]

I see, thanks, i'll do this and see how it comes up :)
