^speed test results^

My log file is below. My stream is currently INCREDIBLY laggy, I feel as though my computer specs and internet speed should be more than enough to have a fluid stream. I appreciate any help I can get! Thanks!

3000 bitrate should be fine with your connection. Yet you are dropping some frames, try some other twitch ingest servers and see if they perform better.

You are mainly lagging frames, meaning that your gpu isn't keeping up. I'd suggest trying to downscale a bit, and perhaps lower the framerate.

 

[Xianahru]

I would strongly suggest dropping your framerate to 30. First, your i5 isnt strong enough for 1080p60FPS encoding, and secondly, flash still seems to have problems with 1080p60FPS.

 

[KingHilly]

that actually helped a lot!! thanks!

Question, (since im noob at this stuff) what does changing my FPS from 60 to 30 do exactly?

for example, what effect does raising the FPS number have and what effect does lowering it have?

Same question for the bitrate, what happens when you raise your bitrate from 2000 to 3000 and what happens when you do the opposite?

Just curious as to how exactly lowering my FPS and down scaling, helped improve the fluidity of my stream!
Thanks!

 

[Xianahru]

Well, FPS work much like the FPS ingame. Having a higher amount of FPS usually increases the fluidity of the gameplay for your eyes. Same thing happens to a stream, 60FPS will look smoother than 30, but your CPU has to encode twitce the amount of frames. Compared to a high resolution this end up in adding very high load on your processor.

The bitrate has is effecting visual quality. A higher bitrate means, a higher upload is needed for the broadcaster and a higher downloadspeed for the watcher. It is measured in kbits.

 

[FerretBomb]

Setting the framerate sets how many frames you send to the Twitch(/other streaming service) servers each second.
Setting it higher makes the gameplay motion appear smoother... but your CPU needs to encode all those extra frames, and your bandwidth has to fit them all into the same bitrate.

By using 60fps, you essentially double the amount of work your CPU has to do (or more!), as well as the amount of data that needs to be sent over the same bitrate link.

I'd also strongly recommend running a 6MB test at http://testmy.net/upload as Speedtest tests 'dead file' transfer speeds, which can spike and dip significantly... livestreaming relies on your constant available throughput (of which testmy will give a better indication). It's unlikely to dump you to 1mbps, but if you actually get 35mbps constant, I'll be outright shocked.
Though yes, 3000-3500 is a good maximum to stick with... unless you're a Twitch partner, you can't enable the Transcoding options, which means whatever you send, your viewers will have to download at to be able to watch. And if they don't have that rate available, the stream will hitch, hiccup, lag, and look bad for them. So 3000kbps is a current 'ballpark' range that covers a majority of those watching on low/mid-range broadband comfortably.


Downscaling (not reducing your bitrate which is different), the smaller the image sent, the more of your bitrate can be spent on making it look good/maintain a constant framerate. So a 720p stream can look smoother and clearer than a 1080p stream at times.

Also, avoid Monitor Capture at all costs in Windows 7, especially if you are doing high resolution or high frame rate streams.
