Question / Help stuttery video no matter what I try

[JedimindhaX]

Hi,

I'm trying to use OBS to do some local recording, but no matter what I try I get laggy/stuttery video. The weird thing is, when I'm playing there is 0 fps lag at all, perfectly smooth! What am I missing here?

Here, I uploaded my latest log. Please have a look someone.. anyone xD

well it's obviously this part.. but how do I fix that?

03:27:59: Total frames rendered: 6573, number of frames that lagged: 2540 (38.64%)

My system:
OS: Windows 8 Pro x64
CPU: Intel Core i7-3630QM 2.40GHz (at 2401 MHz)
Memory: 16GB
Graphics: 2x nVidia GeForce GT 650M (SLI)

Should be more than capable of doing the job

Change the preset from slow to very fast and see how it fares. Slow is meant for EXTREMELY beefy systems and is very hard on your CPU you have a 2.4ghz i7 assuming this isn't over clocked and even so my i5 is a base of 2.90ghz so your clock speed is low. use very fast i doubt you can use slow.

I had it on veryfast when I started, same result, stuttery video.. less stuttery yeah, but still stuttery. For some reason during the rendering some frames get messed up or something :/

okay scratch that, equally stuttery on veryfast :>

Next suggestion I have (while i'm not sure if it'll fix anything) is try upping the bitrate. But i honestly haven't done much with local recording. But lagged frames normally means your CPU or GPU can't keep up.

bitrate won't help it, but thanks ;x if my cpu or gpu wasnt able to keep up it would lag my game as well, not only the video... you would think, anyway. But game is totally smooth. Sigh. Maybe I should try windows 7, idno.

Any developer care to weigh in?

Can you lost a new log of you using veryfast?

Also, try raising the crf a bit to see if that helps lighten the load.

Can you post an example of the stuttery video?

Yo! Here's a vid for crf=20:

here one for crf=15:

It did make a bit of a difference, but it's still weird to me that the ingame fps is fine (you can see it on the vids, on the right (green text)) but then when the video has to be rendered the fps in the vid is really low :s it seems the vid is rendered really really quickly as well after i press stop streaming, like it takes a second or whatever and it's done. shouldn't it take longer??

I added the log as attachment. Weirdly enough the amount of frames that lagged during render is muuuch lower than last few times I tried. But the endresult is the same as you can see, hehe.

I used veryfast on both, btw.

Side-note: I can run that game (Smite, unreal 3 engine) with every setting on highest @ 100+ fps, online. Everything is on lowest now, for recording.

Are you recording these videos to the same hard drive that the game is running off of? How fast is your hard drive? I wonder if it might be a problem saving to disk somehow? Kind of a shot in the dark, and i would think that would appear in the log.

Windows on SSD, game on 5400rpm HDD, recordings on different partition of same 5400rpm HDD.

Maybe try a different strategy: remove the crf x264 setting, set your bit rate and buffer to 8000/8000, and quality to 10 and see how that performs.
