Question / Help Elgato HD 60 Stream hitching

[hkfortyone]

Hello all,

I'm running the Elgato HD 60, and I've been encountering noticeable graphical stuttering on the device when streaming. The device records locally fine, and Obs isn't reporting any dropped frames, so I'm not really sure where to look. It becomes immediately noticeable when there's anything more than very slow screen movement, things begin to get 'framey' looking.

Recording locally doesn't show any evidence of these issues.

All of my settings are within the normal sane boundaries (that I'm aware of). Speedtest always give me 8-11 up, and pingtest to near the are of my twitch server is good as well.

One oddity I have noticed is that the preview window also gets jumpy looking until 'Use Buffering' is flipped on to 0, which also fixes audio desync issues with the device I've had.

The drivers overall seem a little touchy, to the point where I thought my original device was bad and exchanged it, but the replacement behaves the same.

Any help or ideas would be greatly appreciated. This thing is giving me a huge headache. :)

May I see a video of the problem?

I hope you're not capturing HDMI, because a PCI-E capture device would have been far, far less of a headache for doing that. They don't have compressed signals, they don't have delay, far higher performance than USB 2.0. You should never actually buy a USB 2.0 capture device unless you're capturing something that PCI-E devices can't capture, like retro consoles for example. But that's just my opinion.

 

[hkfortyone]

Thanks for the reply, Jim. Yeah, the hd60 captures straight HDMI, no legacy ports. USB 2 was a concern for me as well when I purchased, but USB 3 options seem to have extreme compatibility issues. Is there a list of PCI-E cards that are known to work well with OBS? I have an AverMedia live gamer HD on the way to test with, just concerned a lot of people seem to brick theirs doing the required firmware update, but I'll keep my fingers crossed.

In this one, oddly enough, it is doing its normal hitching for the first 20 seconds, then the sound gets out of sync, cuts out, but after the sound returns, everything works like a charm! Camera pans are smooth again, scrolling items render fine. More often than not, though, the output resembles the first 20 seconds. This makes me curious if perhaps it's a sound sync issue that is somehow also throwing the elgato or twitch for a loop when it goes out of sync, resulting in the choppy stream.

I could have sworn I saw a post from you before -- your stream seems out of sync. I wonder if this has to do with the new delay stuff they're doing. They put in variable delay to the HD60. I need more testing with it. I admit it may not work correctly right now.

One person apparently set their "use buffering" value to values like 2000 and it supposedly fixed his sync issue for some reason. You might want to increase the number and see if it has any effect on the result.
