Hi all - Im a newbie to OBS and so far so good. I am using it to stream live gigs though FB live and its working great. I have found plenty of support via videos and on the forum so thanks for that.
I do have a few questions and I would like to start off by asking about the video. I am using a Microsoft HD-3000 and its is ok - but just ok. There are lots of flashing lights in the gig and the colours do not come out on the screen as we see them in the room. Even when the lights are static blue or red can show as white.
I am guessing that is down to the camera itself, but are there any settings or filters we should be using to combat that?

Thanks in advance

It sounds like your camera is getting overexposed. I'm not personally familiar with that webcam, but most have an exposure setting that can be turned down so that your colors aren't getting blown out to white.

Unfortunately, you're at the mercy of the webcam here. Webcams like a lot of light so they can use lower exposure, but trying to record gigs in dark settings results in what you're experiencing here -- either the entire scene is too dark to make out well, or your light areas get over exposed. There's just not a lot of dynamic range that the sensor can handle.
 
Many thanks for the reply. I will have a look at exposure. I also notice that the resolution is set at default and currently the image is only around 2/3rd the size of the screen. The camera max resolution is 720 and if i set it to that I get a nice full screen of image. Being new though I dare not use it at anything other than default fro a live stream. Do you think it would be ok at 720?

Thanks again

Webcams all behave differently when it comes to changing their resolution. You should be fine raising it though, you're not going to break anything, and you can always just remove the source and re-add it to get back to default settings.

I will say this about "resolution" when it comes to webcams. Resolution is just the digital resolution that is sent from the camera to the computer. The image sensor has its own optical resolution which may or may not roughly align with how much detail that maximum resolution has. Case in point, the Logitech c920 is one of the most popular webcams out there, and it can output 1080p... but its actual clarity is more along the lines of maybe 720p.

What you're describing though sounds like it's taking the full-frame sensor and just cropping it in for the "default" resolution, which isn't giving you any more clarity. In this case, absolutely use the higher resolution, as this gives you more of the actual sensor to work with.

Do testing. See what works, and what looks better. If you have any questions about settings which you're not sure of, don't hesitate to ask -- some are completely useless for your purpose, but the knowledge may lead somewhere.
