Chroma Key replacement in Logi Capture

    I have been trying to figure this out too.  It would make sense if you could overlay it on top of a second monitor source.  Would be better if you could insert a photo or video as a source.

    This is a problem for me too. Chroma Key is pretty useless without the ability to replace the removed background with something. When I import the file into a video editor, the video editor either reads the background as black and won't use black as a chroma key color (because honestly, why would it) or else reads it as...something else, but what it does NOT do is remove the black background that Logicapture recorded instead of the removed background. I was hoping Logicapture would provide more granular control on the chroma key, but... well, it doesn't, and also doesn't do anything useful.

    Very frustrating.

    I hope someone from support answers this question!  I want to change the background using the Chroma keys.  Why offer Chroma keys if a green screen function is not supported!  Is there a firmware download available or do I have to buy the c922 or later webcam.  Very frustrating, please answer tech support!  Thanks!

    I'm not tech support, but I downloaded OBS Studio (free and fairly easy to use) separately and linked my Logitech webcam to it. Of course, I had to watch a few youtube vids to help me out, but I was able to customize a greenscreen and use any image/video in the background during livestreams via OBS. I'm very happy with the performance thus far.

    The chroma key feature works fine. You just need to give it a second video source. I usually put a youtube video on my second monitor and have it full screen. Then choose your second monitor as the source for input 2. Then select the 1 over 2 option at the bottom.....Viola !!

    Hi

    I tried the advice above and got this result. Please look at the screenshot. I guess I'm missing something perhaps I don't understand what you mean by the 1 over 2 option at the bottom?

    Thanks for you help

    John McCarthy  I just figured out you can resize and move the small window that you are in.  Hover your mouse to a corner and click and drag.  This would fix the issue if you are in front of a green screen with good lighting and have the chroma key on.   Crappy way to implement, IMHO, and you have to discover this by accident.

    Thanks Timothy Armstrong, but this stills does not seem to work.  Are you using the c920 webcam or a later version?  I am not using a second monitor, complicating this even more.  Too bad Logitech did not make this process as intuitive as the rest of the interface. I appreciate everyone trying to figure this out!

    I am using the C290.... in the above screen shot I have circled the 1 on 2 selector. You can see the contents of my second monitor. Give me a few and I will see ho to do it with 1 monitor.

    1. open youtube find a video for your background. make it full screen..

    2. In Logi Capture select source 2 and scroll down til you see your broswer listed 

    3 select 1 over 2 option at the bottom.....

    that should do it..

    OK, I can get this to work except for one problem: I cannot increase the size of the camera window to the same size as the screen. So if I use chroma key, i my foreground image is limited in size.

    Any updates?  As Timothy Armstrong's (very helpful) post shows, this only replaces part of the frame.  The only other option I can find is to replace the green screen with black, which is pointless.

    I posted a related question with a bit more detail.
    Background replacement with C920 + green screen (Chroma Key) + Logi Capture

    OBS is the way to go. However my experience is that the Chroma Key effect, even with a proper Elgato Green Screen, is not fantastic. I think it is due to the quality of the camera in the first place that is not fantastic.

    +1 to all of this. Capture's lack of support for full FOV chroma key background replacement is incredibly stupid. The lack of official response too <<<

    That said, the latter seems to be PFTC for Logitech support in general. If something doesn't work out of the box you can rest assured that it will never work as Logitech has no interest in user feedback of fixing anything.

    The problem isn't the camera - chroma key works perfectly with my green screen in Zoom with the C920 - nice clean sharp edges and really looks like I'm in the scene behind. The problem with Logi Capture is that it doesn't let you set the key colour, there are only 2 options - a garish luminous green or blue. The green doesn't match my green so has loads of dots flickering all over the background and horrible fuzzy edges. I am amazed and disappointed at how bad this software is.

    2 things are needed to make this usable, both included in Zoom:

    • A selection for the chroma key colour. In Zoom you just click on the key colour then select a section of the picture (eg your green screen) to use as the key colour.
    • A full size 1 over 2 source overlay so you can just have a background behind your cancelled part of the picture.
    • Or even better - have source 2 to be able to select a picture or video file to use as background. To use a background with Capture it has to be full screen with nothing else in front of it, otherwise you get the Windows title bar and frame.

    I won't hold my breath.
