Hardware?

[Bleever1]

I’ve been podcasting for a long time with a yeti microphone and a black magic recorder and a little Sony video cam.
Seems like lately I’m getting all kinds of lag on my video. The yeti microphone is USB connected to the Mac laptop but the Sony goes through the black magic. I think that’s the problem. Seems like there should be a video/audio capture one piece unit. If I have to get a new camera and microphone and a new capture device I’m cool with that I just got to get a better podcast… Is there a simple solution? Thanks for your help.

Lots of options/approaches, but depends on your specific requirements/expectations, and especially budget.
For simple setups (not necessarily best audio quality), plugging a mic directly into a camera often helps in simplifying audio/video routing and keeping those in sync.

And beware the term 'lag' as it can refer to many different things, each with their own cause and solutions. Are you talking about locally recording in OBS, and the audio and video not in sync, with sound ahead of video? In terms of video taking longer to process on your computer than audio, than is normal/expected, hence built-in OBS setting to delay audio [again, if mic plugged into/part of camera, then this less often an issue]

And yes, there are plenty of modern cameras that can output audio and video straight into computer, without a capture card. HOWEVER, to get decent video resolution, you'll need USB3.x (vs older USB2) I mention as you didn't state which model computer you have

For me, I prefer to get working what I have than spend money to overcome small technical issues (if that is indeed the case. And I'm a techie by profession, so I don't let a computer be in charge of me). In the Windows OS world, Black Magic has had driver issues requiring updates to work with latest Windows 10. Assuming you've done OS updates as well, making sure Black Magic is up-to-date with known good software/firmware would be a first step (unfortunately latest isn't always best... ymmv, something you'll have to research or get other inputs)

Then, recognize that real-time video encoding is VERY computationally demanding. So old computers will struggle. Operating System optimizations may be required, as well as careful OBS settings to not over-tax a system. And audio/video not staying in sync is one symptom (sometimes) of an overloaded system
