Question / Help Record Capture and Stream

[johnnyg]

I want to use OBS for a live event this weekend, but I'd like to be able to record both the final stream with all my scenes set up, and the direct output from my capture device that will be hooked up to a camera. I'm on a laptop with Windows 10, the capture card is a StarTech USB3HDCAP. Is there a way to do this, or an extra tool to grab that will let me?

You can open two instances of OBS at the same time and set them up differently to do what you described. With a caveat that you can only game capture a source once. Definitely test it and get it working well before you need it.

The second instance of OBS can use a monitor capture in some cases

Oh cool, I'll give it a try tonight when I have all my hardware with me. So there's no exclusive lock on the capture device while OBS is streaming?

Yes, no other program can be capturing any source that OBS is using. monitor capture being the exception.

I have no problem adding the video capture card source to multiple OBS instances when I do it.

that isn't what I meant.

Okay, I was able to open multiple instances of OBS Multiplatform, but not OBS Classic. It looked like the 2nd instance of Multiplatform wasn't able to capture from my capture card, it just showed a gray screen. So looks like this won't work?

I do it using OBS Classic, haven't tried Multiplatform yet (mainly because I decided not to stream the game I'm playing currently, only recording it).

Do this forum search to see various posts on how to get it to work: https://obsproject.com/forum/search/2799314/?q=portable+multi

But generally, you add -multi to the OBS shortcut target to allow multiple OBS instances to be opened at once, and you can add -portable to the same to force them to save their configuration separately from each other. Its easiest to use the 32-bit version for one setup, the 64-bit installation for the other.
