Yes, please, that would help so much. OBS seems to be designed for static setups and a single output stream. In my case, I have a setup that changes often (for example, connect a USB video device that processes input from a microscope). I thought I would be able to record multiple video streams at once without burning them into a single output stream (e.g. to multiple files, or a multi-stream file), but this turned out to be difficult without hacks.

The Branchoutput plugin[1] is what you are looking for for multi recording/streaming. It allows you to add recording (or streaming destinations) to individual sources, scenes and outputs via the video filter settings. It is really quite powerful.

		Thanks -- this does look like it would do this. But I'm wondering if this entire setup isn't completely overkill. All I need is to record multiple video streams simultaneously. I currently do this by launching multiple Quicktime Player apps and clicking "record" in each one of them...

Have you considered using GStreamer pipelines for this? And taking it one step further, if you want to use OBS generally, there's a plugin for OBS that allows you to integrate pipelines too.

The common case for the plugin is to do some preprocessing before importing the video into OBS, but you can also use the pipeline as a video filter, which is really powerful, because you can inject a filter into not only a single source, but also at any level of a nested scene. So you can scale/composite several inputs together and then the video filter can copy the source stream and encode/tee it to a file output. Might still be considered a hack of sorts.
