Occassional Max Audio Buffer issue with Elgato (OBS)

I have consistently posted about this problem for the past 6 months on the OBS Discord and rarely ever get a meaningful response (your specs aren't enough for 4K is the tl;dr of what I get, despite me knowing very clearly it is not my specs) What has been happening: For inexplicable reasons, recordings via my Elgato 4K60 MK2 would suddenly start producing very strange audio crackling. This started sometime in the past 6 months and happens on 2 different PCs. This PC was the one that caught the problem today, the other PC runs a 7950X3D/4080. This does not happen when a game is recorded locally on PC via game capture. This only happens like once a month and we have no idea how or why it could be happening....

Revelator IO24 vs IO44

Are the internals of the io24 and the io44 the same; are the values presented in julian krauses' review of the io44, the same as the internals of the io24. Both are the same price on amazon. The io24 is older and has 2 mic/line combo inputs. the IO44 is newer has 1 mic and 1 line input, I will only ever use 1 mic and 1 line input, which both have. Which ones measurements are better? even if tiny...

Something eats storage in the background and I can't figure what.

Alright so, the red flag got raised when I was trying to install the more recent W11 update, but for some reason windows are unable to install it. Therefore I am very certain there is a Drive C cluster going on, plus I had 20GB left of storage yesterday and today only 10. Any ideas what could that be?

How does scaling affect VMAF scores?

For example, if a fast paced 1080p lossless source video is scaled to both 936p, 720p etc etc, without limiting bitrate, i would imagine the higher resolution would be prefered by vmaf. But if we limit bitrate to 6k or 8k for the context of streaming, I would personally prefer 720p over 936p, but how would vmaf scores be affected?...

2 pc setup help (Rode Caster Duo

Hi Iโ€™m new to rode and have been using GOXLR for like 4 years. For some reason Iโ€™m struggling here. I canโ€™t figure how to get my OBS sounds (alerts) or my Spotify (music track for twitch) to separate. In goxlr I just use the MUSIC output and then add it in OBS and remove it from vod track and OBS is just on system sounds (Desktop audio) but I canโ€™t figure out how to do that with the Rodecaster hardware or software. :woahLUL: plz elp.

OBS on Linux - High average time to render

preface Just switched one of my systems that I use to host applications from WIndows 11 to Ubuntu 23.10. I use OBS + Advnaced Scene Switcher + NDI to share my screen during collaborative sysadmin / software development sessions with my peers. I also use this machine for watching streams while in Discord calls, to offload resources from my other machines (works great). So, I have reasons to use GUI Ubuntu. the issue When I got around to configuring OBS I noticed that my average time to render frames was 4x+ higher than what it was on Windows (9ms vs 2mx). Same computer/hardware, screen capture source of the same 4K display. I'm using XSHM as opposed to PipeWire for screen capture. With PipeWrie I get 50ms+ render time, vs 9ms with XSHM. When I'm actually interacting with the PC, the render time jumps into the mid to high teens at times; which results in frame drops. Though, the output isn't unusable or anything. suspicion...

New Elgato 4K Pro - No 4K60 in OBS

So, I bought a new 4K Pro to stream and record my PS5. However, I'm can't get it to display in OBS in 4K resolution. I am aware of the 60Hz limit, as the attached screenshots show, I have my PS5 limited to 60Hz, and both 4K Capture and the Capture properties in OBS show that the input is 2160p60. However, it still only displays a picture in OBS when I am using 1080p resolution. Not sure what is wrong with my settings.

OBS Video Capture Device only showing 1080p instead of 4k

Elgato 4K Pro. The capture utility works just fine but no matter what I try in terms of refresh rate and resolution, OBS will only show 1080p 60

OBS Audio Monitor

Hello, after watching Vox's "Will THIS OBS Studio plugin kill Voicemeeter?", I decided to give OBS a try and the plugin as well since I've been using Voicemeeter (VM) and wanted to have a program for everything (Mixing, recording, streaming, highlights, etc). I don't fully understand the steps, for I've been stuck despite watching many videos in relation to that plugin, and I think I need assistance after trying for hours at end with no success. What I'm trying to do is to have OBS as my VM and route audio from my pc to virtual inputs that I can add effects to (For example to add eq to Spotify), use it as my real time effect microphone output for discord (or with little latency compared to VM), and to also have it set up so I can record a quick highlight or clip at any time (replacing NVidia Shadowplay)....

Source Record

Does anyone know if Exceldro is still working on Source Record? The last version is for OBS 29. Was it replaced by something native? Or, should I just use the Aitum Vertical plugin set at normal resolution? There seems to be a number of unhappy users on the OBS forum for the plugin.

Whats the best way to test and compare different encoders with the same video file?

Unsure how to go about testing x264 vs nvenc h264, for streaming purposes. I've seen lots of benchmarks etc. I've tried shutter encoder but the nvenc clips come out looking worse than x264 medium/fast, would want the encoders im using to be same as obs ones. I used Nvidia ICAT to compare split screen. Doing all this for fun, i understand no one except me will notice or care about the difference. Something is making me think apex foliage looks worse on nvenc even with p7...

Streamdeck + Stop Raids

I'm curious if there is a native solution I'm not seeing, or even a plugin solution that allows for some of the options in the Twitch "Quick Actions" to be toggle-able on a streamdeck. Specifically, I'm looking to set the "Stop raids for one hour" flag when I'm nearing the end of stream to prevent last minute raids from coming in. I'd set the quick actions as a dock in OBS, but there's limited real estate there. Would def prefer to have a streamdeck button to set the setting. is there a /comman...

Very large recording size files @ CQP - 20

Been trying to make OBS recordings for a project I'm working on. My resolution is 1080P and at 60 frames per second. I've set it for CQP at 20 (which had been recommended to me in the past), but it seems like despite using it.. the file size is coming out usually exceptionally large, the few recordings I've done have come out around 90,000-100,000 kbps total bitrate, which is absurdly high for 1080P. This would definitely become an issue in the long run since the project I'm working on requires many video files....

Really bad stream lag last night

Not sure if this was just a coincidence โ€” I streamed last night and was dropping frames like crazy. The bandwidth bars at the bottom of OBS were red and showed only around 2000kbs. The only thing I changed for this stream was installing the Aitum plugin, but I have streaming disabled. Iโ€™m only using it for recording. Screenshots attached. Not sure if it was my ISP last night, or something about the Aitum plugin. Iโ€™ve never had issues like this before, so I thought Iโ€™d ask!...
