Assume for the sake of this discussion all of the following:
* I realize that OBS allows 3 different types of downscale filters to be used to scale your canvas on output if not symmetric. As far as I can tell, this filter choice doesn't apply to in-scene source size adjustments. But that assumption may be incorrect and maybe OBS uses the filter selected here for both overall output and in-scene downscaling?
* I know I can potentially stack sources a little differently to get a better resolution from each source individually. That's not relevant to this discussion.
Follow Up Question: Does changing the cameras from 3 x C920s to 3 x Sony A6400s alter the above assumptions? Does Sony's native downscaling tech meet or beat what OBS uses to downscale an image in a scene? I AM aware that the A6400 can only output at 1080 (at the lowest). Assume it could downscale to 640 for the sake of this discussion.
Follow Up Question: Knowing that I have unlimited computing resources, is there a way to utilize better downscaling of a video capture device source in OBS within a scene? My computer I would imagine is much more capable than a mirrorless or DSLR camera and as such, should have access to a wider range of filters to perform "better" downscaling.
Thank you for your thoughts, comments, clarifications, etc... and realize that I'm a complete noob with regards to cameras (and many other unrelated topics).

- My OBS canvas is 1920 x 1080
- My output resolution to Twitch is 1920 x 1080 (60fps) at 6000 bitrate
- I have NO hardware limitations (I have all the video/processor/USB/internets)
- I have 3 camera sources in my OBS scene that I need to display simultaneously in one scene
- Each camera can output at either 1920 x 1080, 1280 x 720, or 640 x 360 (for the sake of this discussion)
- My goal is to display each camera's output side-by-side at 640 x 360 so it takes up the entire width of the canvas.
- Natively set the output resolution from each camera to 1920 x 1080 and resize each source to 640 x 360 in OBS?
- This will result in a significant amount of downscaling
- Natively set the output resolution from each camera to 1280 x 720 and resize each source to 640 x 360 in OBS?
- This will result in a less significant amount of downscaling
- Natively set the output resolution from each camera to 640 x 360?
- This will result in NO downscaling
