Question / Help Turning Prerendering off?

[ThePhantom123]

Hello, I just wanted to ask if there is a way to disable the rendering within the recording. This lets my video lag a bit, so thats a problem.

I hope there is a way, otherwise I can't use the programm =I

I'm not sure what you mean. You can disable encoding while previewing, but you can't disable encoding while recording...because recording is encoding. Is that what you mean?

Sorry, I don't know how to explain it^^

Well, there are rendering programs like Camtasia or Sony Vegas that convert .avi to .mp4 or something like that. If I understood it right, OB does that directly. My questions was how to disable this.

If thats encoding, im sorry. As im german, I don't know every word^^

Oh, and here is my log! :D

That's not really what OBS does. OBS takes raw video data and encodes it into an h264 video stream, which is then sent over the internet via RTMP, and sometimes also saves locally as an FLV or MP4. If you disabled encoding in OBS, it would cease to do anything relevant, unless the only thing you were using it for was its projector output.

OK. Then I just wanna ask what Bitrate I should use. Now it is on 6000kbit/s and I think that could create lag too.

Are you streaming, or just recording locally? Higher bit rate doesn't really add load to the encoding process, but if you're streaming with a high bit rate, you could run into issues with dropped frames or poor viewer performance.

Having said that, you only have a dual core CPU, which isn't that great for live video encoding. You can try downscaling your resolution, and possibly changing you x264 preset to superfast or ultrafast. And if this is a local recording, you can compensate for the quality loss by increasing the bit rate even more.

Here is a guide for local recordings, if you're interested: viewtopic.php?f=18&t=2972

Yeah, I wanted to record locally. But it looks like that won't work, as of the lags =I
