Question / Help Want to Transition to OBS from Fraps but get jumpy fps

Newcon · Jun 16, 2013

Hello,
I am new to OBS I have literally just downloaded it and followed a few guides for the configuration, although perhaps I'm doing something wrong. I have a Youtube channel that I make videos on, which I currently use Fraps for. I have been told that OBS significantly decreases the amount of CPU usage and file sizes compared to Fraps. I would like to transition over to OBS completely however, with OBS It seems like I'm getting random frame rates ie 30-70 and it looks really choppy when I watch the footage over, yet when I use Fraps it's at a constant 30, or 60 fps.

My PC specs are
i5-3570k @4.7GHZ
GTX 670
I think that's all that is relevant interms of streaming directly to file.

I have just got into Bf 3 (I know i'm a late bloomer) and the frame rates when I watch it over seem to be less than 30 and it doesn't look smooth at all to watch yet when I use Fraps it looks really smooth and crisp. The quality on OBS I've managed to get nice but it looks choppy.
I'm not sure if this is a common problem but hopefully you guys can help me out.

i followed the guide from :

viewtopic.php?f=18&t=2972

to do my settings and they are as follows.

Encoding
Use CBR: Disabled
Quality Balance: 10
Bitrate: 1000
Use custom buffer size: Enabled
Buffer size: 0

Advanced Options
Use custom x264 parameters: Enabled
Custom x264 parameters: crf=15

I have the latest graphic drivers so I don't think that is a problem I just don't want my videos to look choppy or I'll have to keep using Fraps even though I believe OBS to be a better quality programme!

Thanks for your help in advance
cheers

Im not sure about your problem but i had the same exact problem with dxtory coming from fraps. im going to try obs now and see if it helps.

SirCrest · Jun 16, 2013

The reason for this is that Fraps forces your framerate to match a multiple of your capture FPS E.G. Capturing at 30fps, you can record 1 to 30fps, 60, 90, 120, 150, 180, 210, 240, etc. But OBS and Dxtory do not lock them and let them fluctuate whenever, so both programs basically grab the closests frames they can in the ideal window.

This effectively causes microstutter because the frames they might grab do not have a consistent render time. Setting Synchronize FPS in Dxtory solves this but locks the framerate down similarly to Fraps, but you get buttery smooth video.

I don't know is OBS has this option, but either way you cannot have the best of both worlds. You either sync the framerate and have smooth video, or you don't and have jumpy video.

Newcon · Jun 16, 2013

Hmm alrighty thanks for clearing it up, I don't really want to stick to Fraps, but the jumpy fps will cause me to :(. It just looks bad when the fps spikes up and down making it look choppy - how annoying!

Do you think you could post your log? http://obsproject.com/forum/viewtopic.php?f=6&t=97

FerretBomb · Jun 16, 2013

Please do post your log. You can get buttery-smooth video in OBS as well, but there may be other issues causing your problem, which the log will tell us and we can get you fixed up most likely.

Most common is using Monitor Capture, which is/should be a 'last resort only' capture method, as it's SUPER slow and tends to lag frames like crazy.

Newcon · Jun 16, 2013

I'm new to this whole thing, I'm not sure what you mean by log hopefully you can can help me here. I thought I was just being stupid and that the capture monitor button was ticked as well but i deleted that and merely just had the Battlefield box ticked. When I took out the monitor capture it looks smoother to play but when I watched it back even though the whole time I'm getting more than 30 fps, if I watch it back it's playing at around 23. It looks choppy as well :S. Cheers for the help in advance

You have 14% lagged frames which isn't good. I see that you are using the preset "faster", I use "ultrafast" since it uses less CPU and file size is not a big issue for me. You could try a faster preset and see if it helps.

Thanks that has fixed it! Even while recording the frames are higher as well, I just put faster as that was the preset I was using on Xsplit before when I tried it out and it was fine, but thanks very much for everone's help I will now be able to properly transition over to OBS :D!

Krazy · Jun 16, 2013

Mmm, if you can manage it you should really be using veryfast. The quality decrease from ultrafast can't be offset no matter how much bitrate you throw at something.

You could also look into using the QSV encoder in the new test builds since you have an Ivy Bridge CPU. It may take a bit of doing to set up, but it will allow for recording your games at basically 0 system impact at all.

The quality suffers even with "unlimited" bitrate? ultrafast and crf=15 looks really good to me but I haven't made a comparison.

Krazy · Jun 16, 2013

Yes, ultrafast makes some serious quality sacrifices, more than bitrate alone can really compensate for.

Newcon · Jun 16, 2013

I've just tested it and it looks choppy if I play at Very fast, still shows 30 fps but looks choppy If I play at Ultrafast it looks smooth, quality still looks good, i'll test it out with Superfast and see what it's like.

Krazy · Jun 16, 2013

I'm frankly a little surprised your CPU has such high frame times even on 1080p with Faster preset. Which game are you recording? Do you have a lot of background processes or something?

Newcon · Jun 16, 2013

Nope I have a stream that I'm watching and when i'm idoling with the stuff I have open I'm only at 10% CPU usage I'm recording Battlefield 3 at high settings. Not running at Ultra so I can record. If I have it at superfast it stays at 30 constant when I watch it over, if I do it at anything higher ie very fast, it looks pretty choppy when I watch the footage.

I also have an SSD which BF 3 is installed on with a second hardrive that I have OBS installed on.

Krazy · Jun 16, 2013

You are watching a stream while encoding? You shouldn't be doing that.

Newcon · Jun 16, 2013

:o oh really how come? I didn't think it would cause problems

Krazy · Jun 16, 2013

It does, it can be a pretty serious performance impact. You can blame flash for this.

Newcon · Jun 16, 2013

Ah right, I'm watching the LCS at the moment, so perhaps that's what been causing the problems, but I wasn't watching a stream when I posted that log this morning I don't think. It's the last game at the moment, so I'll try it out after and see what happens.

EDIT:

Ok I've done 2 recordings 1 on Faster with nothing else running other than BF, OBS and Firefox, and then one on very fast

This is the Faster one:
