Two 4K streams with same video feed

[FFL19]

Does anyone see any problems with running two versions of OBS with the same video feed in both.

Both 4K 16:9 canvas, but one is designed for vertical viewing and the other has the image rotated with black bars on the sides.

Will this be extremely taxing on the streaming PC to be doing two 4K encodes at once? Is there a better way of doing this that I haven't considered?

Thanks

I had OBS open accessing my webcam and opened a second instance of OBS. The second instance of OBS could not access my webcam. You may run into this issue if using a single capture device.

What are you trying to accomplish with 2 instances of OBS?

Thanks for responding. That's good to know.

I'm trying to publish one stream as a 16:9 sideways vertical video and one as a vertical video in 16:9 canvas with black bars.

I think you are going to need a HDMI duplicator and 2 HDMI capture cards.
