Question / Help Slight stream stutters!

[Raezy1]

While streaming I notice slight stutters in my video when I view it from twitch tv. I feel like it isn't smooth like other streams! I was just wondering if I am doing it right or maybe my settings are wrong. I have tried different settings and I still can't get that smoothness going for my stream any help would be appreciated.

When I full screen my twitch recording there are visible stutters in the video, but when I view it normally there are slight stutters.
Link: http://www.twitch.tv/raezy1/b/497800474 skip to around 5.55!

Would like to have a smooth and good quality stream with my current rig, any recommendations would be greatly appreciated!

For future references what would you recommend to upgrade to have 60fps at 720/30 fps at 1080, smooth and amazing quality stream! Thank you in advance

My upload is around 7.6mps, even though different speed testing sites have showing different results.

Your system is pretty good, and your settings -should- be fine. Could you output to file and see if it happens there as well when using a media player instead of on twitch? Just to check.

 

[Raezy1]

The output recording is a little bit smoother than the twitch recording, but there is still some stutters.

 

[Lain]

Hm, I'm not sure what to say, the recording overall seems fine for the most part. Does seem to be some slight jitter, though OBS isn't reporting anything particularly wrong, and your performance report at the bottom seems pretty much flawless. I figured maybe you were experiencing issues with flash, flash can't always decode frames that fast at higher resolutions.

 

[Raezy1]

Is there anything I can do with flash to get rid of the jitter and would you recommend scaling down to 480 and maybe lowering down the preset for better smoothness/quality? Its just that when I open someone else's stream they have very smooth video and quality!

 

[Lain]

I would recommend experimenting with downscale to see if any of the downscale options work better. If nothing works, then it might be more of a capture thing, though I'm still not entirely sure yet. Keep using file output to test the smoothness as the file output with a media player is the best way to know for sure.
