Record 2 screen---1440p+1080p

[KCRC]

Hi All:

I got 2 screen, 1 with 1920/1080, the other was 2560/1440.

I would like to record 2 screen together in 1 video, with final output at 1080p.

I tried google it but most guide out there seems discuss about having 2 monitor at same size (aka 2 x 1920/1080p). I noted in that situation you simply increase both canvas and output as 2xwidth/1xheight. That is 3840/1080p.

I tried the above setting but it seems incapable of recording the 2560/1440 screen in full.

Is there some setting I missed to perhaps downscale the 1440p screen's output to 1080p, so it can fit the 3840/1080p canvas?

Thanks,
KC

What are you doing in the first place?

Anyway, I'd be tempted to do this with two separate Display Captures, one for each physical screen. Then arrange them on an appropriately sized canvas to recreate your logical layout.

If they're different sizes, then you'll have a lot of black area, or you can scale one to make them fit better. But if you're scaling one to make them equal, why not set them equal to start with, in your OS settings, and then capture that?

I was recording a game called SimSig and I need to display both screen to show the full diagram. I can consider leave one side with black area (as the diagram was relatively simple).

The 1440p screen was, er, not configurable in my laptop control.

I still want to know if theres a way to make the 1440p scale down (or the 1080p scale up), but if I didnt figure that out I suppose I can just do a (1920+2560)/1440p, and leave some black space on the 1080p side, perhaps fill up with some info box.

...perhaps fill up with some info box.

Depending on your end goals, that might actually be a "happy accident". See what you can do with it.

The Window Capture stays with its assigned window, even if something else is covering it, so you can get a total captured area that is bigger than your total physical area, with all of it unique.

Just don't minimize the captured window. Minimizing tells the OS that you can't possibly see it, and so it stops drawing it, which gives nothing to capture. Keep the window up, and just allow something else to cover it.

Hmmmm didnt know that you cant minimize OBS in window capture mode. Lucky I can hide it behind the diagram I suppose.

You can minimize OBS just fine. Just don't minimize whatever you assign a Window Capture source to.
