Question / Help Any capture device on Mac that does 1080p/60fps AND supports OBS Syphon?

[TheMuso]

One work-around is to configure CamTwist to use a 1080P 60 resolution and frame rate, as well as configuring the Magewell to input at 1080P 60. You can then feed Camtwist's output to OBS via syphon. This configuration is all done within CamTwist's preferences.

I have made a guide on capture cards and OBS MP,maybe it will work for you guys:

BRILLIANT. This works perfectly and I think it's finally the magic solution I'd been looking for. Thank you!

I spoke a bit too soon. It seems to be working out, but the feed into CamTwist is stuttering. Have you run into this or know what might be causing this?

Uh,this thread might be old,but I think this is the right thread.

I have made a decision to buy AverMedia Live Gamer Portable(or LGP Lite) or Hauppage HD PVR Rocket.

Also,to capture my screen,I will follow this two tutorials:Record Mac Screen & Sound w/ Elgato Capture Card
LGP OBS Mac Streaming Guide Updated

The thing I want to ask,how much CPU does it cost?Will it really make my Mac laggy?

Specs:Macbook Air mid 2011 '11
2GB RAM

@bowlingotter, does the Magewell work at 1080p60 natively in the latest version of OBS MP? (0.12.4)

When you open the properties for the capture card, there is now a checkbox that says "Use preset". If you uncheck that, you should now get a ton of new options for setting resolution and frame rate manually, which you might be able to use now to set the Magewell to 1080p60.

 

[bowlingotter]

@dodgepong I actually just tried this last night. Unfortunately, even if I select 1080p60, the image is still no better than choosing the 720p preset. It still comes in at a 720p size that needs to be stretched to fit the full 1080p canvas

 

[dodgepong]

Can you post a log of when you tried that?

Could you post the whole log, for the sake of completeness? In case something was missed that you didn't realize was relevant.

Ok I think I've figured it out.

When I go to add the Magewell, if I select the Magewell as the capture device first while the "Use Preset" button is still checked, then uncheck the box, and then manually select 1080p/60fps, it still comes up as 720p in the window even though the options say 1080p.

However, if I go to add the capture device, FIRST uncheck "Use Preset" and THEN choose the Magewell capture device in the drop-down menu, once I input the 1080p/60fps, it actually did come up as 1080p.

I've managed to consistently recreate this behavior in both cases.

Pretty small bug, and otherwise I am so happy this is working I can't even tell you.

 

[Gerry]

Yes this work but when I go into output settings, the maximum size I get to select is 1280 x 800 even though I set it to 1080p when added the logitech c920 webcam

- I should add that I'm using a 13" macbook pro

If you want to change the resolution of the video, you have to change that in Video settings. That is kind of off-topic from this thread though.
