Question / Help Clipping the Corners of a Video Capture Device

[Ian Bachelor]

I'm trying to setup a Smash Bro's overlay, and the design I'd come up with was to clip the corners fo each image to increase the total size of each video. I ran into this issue after the fact, not thinking about never actually having done something like this in OBS. Is this possible anyway, or am I just gonna have to make a new overlay for this scene?

Here you can see the mockup of the idea

And here is the final design

In OBS this is not possible. But OBS-studio has an image-mask filter, which can exactly this.

I'll be perfectly honest, I'm not sure what OBS-Studio is. All I've ever seen is base OBS and the multiplatform rewrite, along with a couple hardware encoding forks. Is this the same thing as the multiplatform rewrite? The github page isn't quite clear to me on what exactly is different about it.

If it is multiplatform, that is a tad difficult to work with considering that I would really prefer to have the NVENC support that is only in OBS right now.

OBS multiplatform = obs-studio

 

[ThoNohT]

Ah yes, apologies. They are the same thing. I do believe hardware encoders are planned in the near future, so that might solve your problems.

There is not much we can do about it in the meantime. Development on OBS has halted to make place for OBS Multiplatform, and there really is no other way to do this than with the image mask.

Ok, so I've gone ahead and tried using obs-studio, and was able to do what I wanted with the layer mask, but now I have an issue related to that. The layer mask carries over to other scenes where I don't want it, and I can't have the same device as two different sources. Is there a way to toggle the layer mask with a hotkey?

 

[FerretBomb]

Nope. Filters are locked to the source in MP, frustratingly enough. One of the reasons that OBS-MP really isn't ready for prime-time just yet.
Means that you can't crop a source differently per-scene either, or use one input with variant filter stacks for different scenes (like if you want to have a standard webcam, and an altered version in another scene to mimic something like the Metal Gear CODEC screen).

Personally I'm hoping for a Maya hypernode/hypergraph style source setup to replace the current filter-stack. MP is still under development. I'd recommend sticking with Classic, and just putting a square overlay in the middle to hide the overlap point, or otherwise revise your layout around the limitation.
