Question / Help 720@60 stuttering and quality issue.

Hister · Mar 1, 2014

Hey guys, Im trying to stream a high motion game such as COD Ghosts, BF4 at 720p@60 but it seems like im experiencing some quality and occasion stutters on the stream. Ive tried various bitrate/buffer sizes and looked through this forum for different settings from people with similar issues but nothing seems to work for me. My net speed according to testmy.net is 51 down 5.1 up, an I going to need more upload to successfully do this? Ive got my bitrate/buffer at 3500/3500 but dont I need a lower buffer so I dont run into issues with people having trouble viewing my stream? I checked the analyzer and its telling me there are no issues, but as you can see in the video something isnt right. Im guessing its on my end but id like confirmation before I settle with 720@30.

Heres a quick video of my latest settings in action. http://www.twitch.tv/shroomyz/b/507353350

Heres the log.

I know this issue very well. It isn't down to your system or the way you have anything setup, its a twitch issue. I have no idea how their network works, or what they've done over the past year, but the quality of the service twitch gives has plummeted downhill. I don't bother streaming to twitch at 60fps anymore. It's pointless because of the stuttering and frame dropping.

If you want to test my theory, go make an account at hitbox.tv, and do a 60fps stream there. You'll noticed its much much smoother, and the delay is much lower.

Hister · Mar 1, 2014

That sucks, does it just depend on the user? I mean many streamers stream at 720@60 and it looks pretty good.

That is not a Twitch issue. The Twitch VOD player is indeed crappy, especially for playing back 60 FPS video, but 10% duplicate frames is something on the streamer's end.

Hister · Mar 1, 2014

Thanks for pointing that out Sapiens.

I turned off CFR and here is the difference.
http://www.twitch.tv/shroomyz/b/507405786

Still not as clear and 1 stutter that I seen....Would going down to faster or fast on my x264 CPU preset fix the quality anymore?

Also wondering why you're not using the 64bit version of OBS, it performs better and has access to more memory. Oh and keep CFR on ..

Hister · Mar 1, 2014

Good question, for some reason I thought I was, I just built this rig a day ago so simple mistake on my end,

Hister · Mar 1, 2014

Using the 64 bit version does seem to help a ton. Not sure why but the video just doesnt seem as clear as others streamers ive watched. Ive tried lowering the x264 cpu preset to faster but it goes all to hell.

You should leave the Enable CFR box checked. Is vsync enabled? If not, try turning it and see if that makes a difference.

Hister · Mar 1, 2014

So what would be an acceptable level for Total frames encoded, total frames duplicated? Ive tried just about every setting I know and I cant seem to get it below 1% in high motion games like COD and around .50% in games like Diablo anywhere from 120 frames duplicated to 60.

Question / Help 720@60 stuttering and quality issue.
