Question / Help stream lag

melancholyx3 · Jul 1, 2013

For some reason, my vod shows some lag in between (it's just a little). It doens't look smooth like when I am playnig it. I have no clue what is causing this. My down/up is 19mbps/2.5mbps (on test.net). I've played with many settings trying to fix it but I have no clue which setting is incorrect. Here is the log and the vod:

Maybe it's me, but I didn't really notice any lag in that video, personally.

melancholyx3 · Jul 1, 2013

compare my vod with this person's

http://www.twitch.tv/dexus136/b/423623031

the "circle" that approaches looks laggy (probably the most obvious sign of some lag) on mine but not the other person's.

dodgepong · Jul 1, 2013

What do you mean by "lag"? Most people when they say lag are talking about lagging frames. Are you talking about lagging (or desynced) audio?

melancholyx3 · Jul 1, 2013

I don't think calling it "lag" was the right term, maybe "smooth". My stream was less smooth than the other person's

Gol D. Ace · Jul 1, 2013

Well he is streaming in 60 FPS. You're only streaming with 25 or 30 FPS.

Deleted member 3892 · Jul 1, 2013

Ofcourse you can try streaming at 60FPS, but it can be too much for your PC.

melancholyx3 · Jul 1, 2013

Okay, I tried changing the fps to 60 and it looks even worse to be honest.

dodgepong · Jul 1, 2013

Then it's possible your system can't handle 60fps. Can you post your latest log from that 60fps test session?

Yep, that's a ton of lagged frames due to long encoding times. You might be able to do 48fps, or 40fps, or you might be able to do 60fps with a downscaled resolution. In general, 1080p60 is not recommended because of how demanding it is to watch in Flash as well as encode.

I downscaled the resolution from 1080 to 720 and it seems to be a lot smoother. I would claim this to be solved. Thanks!

Why are you using 32 bit obs?

Bensam123 · Jul 2, 2013

At that resolution you're probably bumping against your bit rate. Even more so when running at 60fps (it uses more bandwidth). So you'd probably have to turn down your resolution in order to compensate for your low bit rate. Your quality setting of five probably isn't helping anything, but you'll get dropped frames if you turn it up and it can't handle it.
