Question / Help Logitech C920 set to 30fps and stream set to 60fps

[wtm001]

I'm currently using a Avermedia C027 capture card and a Logitech c920 to stream. For some reason when I stream at 60fps playing Black Ops 2, my webcam is super distorted. I read a thread that talked about making your webcam not suck, but after all of that I still have the same issues. It is possible that the capture card is the issue? I don't have a problem when I'm playing a PC game or doing a screen capture of the game. Also note, I'm always streaming at 60fps. Even when playing SNES games and such. Sorry if this post was all over the place, just was thinking of things as I was typing. Thanks everyone

I'm not sure what you mean by distorted...looked pretty normal to me. If you're referring to normal compression artifacting, then that's normal when playing a high-motion game, as opposed to a SNES game, which is a lot easier to compress.

The webcam is completely pixelated. I've watched other people's streams and I don't see that issue, maybe cause they're streaming at 30fps? I'll have to try it out. I always thought it was because of my outdated graphics card.

No, it's because you're playing a high-motion game at 720p60 at only 2300kbps for your bit rate. If you want it to look better, then you'll need to increase your bit rate quite a bit, such as to 3500kbps, assuming you have enough upload to do so. If not, then you'll need to reduce your FPS to 30 and perhaps even downscale a bit.

Thanks, I have a 5mb upload, I only keep it low because a lot of viewers tell me they're getting a lot of stuttering. I just watched a video where the guy said to lower your buffer size, gonna give it a shot. Thanks for the suggestion

Lowering your buffer size, unless you know what that actually does, is not recommended. Leave it matched.

You'll want to drop to 720p@30fps; it'll really help quite a bit as far as image quality goes. 60fps is mostly psychosomatic (or stat-wanking), unless you have a specific reason like that the game uses sprite blitting for transparency, and running 30fps ends up with the sprite going invisible or staying solid all the time.

For example, I have the option to run 720@60 at 3500kbps, but I still leave it set at 720@30 because it delivers a much clearer, non-artifacted picture, especially during fast-motion scenes. I've tried it both ways, and 60 just ends up with a LOT more blocking and pixellation on snap-turns and scoping.

Thanks for the suggestions dodgepoing and FerretBomb. I'll try these and report back

Dropping down to 30fps has fixed all my issues, thanks for the helps guys.
