Using Blender 2.92.0 and I can only see the Keying Node in Compositing but not in Shading Nodes section. I watched a video of how to setup the chroma key green screen removal using Compositing and managed to successfully remove the green backdrop in the Compositing preview... but then what ? I still see the green screen image in Layout mode. I am not proficient with Compositing hence my confusion with the matter. Any help would be appreciated.

  • $\begingroup$ There is no need for a chroma key node in the shader editor hence no node. Recommend describe what you'd like to do rather just explaining your situation/confusion. Would you like to use the result as card in 3d view? What's your goal? $\endgroup$

  • $\begingroup$ I thought I was describing the situation with my "how to setup the chroma key green screen removal using compositing" in my initial comment. However I'll expand ..... I imported a short green screen video of a visual effect. I simply want to remove the green background. I saw someone using compositing which had the chroma key node to remove greens but I don't know how to then translate that green screen removal in compositing to show it's removal in the layout view and ultimately use it in the render. The layout view still shows the green screen with the visual effect in the imported video. $\endgroup$

  • $\begingroup$ You would have to render the result to OpenEXR and import it back in if you'd like to display the result in 3d view (layout view) for whatever reason. Usually that's not required, in most cases there is no reason having the footage in the viewport, you can just merge the rendering and the keyed footage in the compositor as a post process (the reason why I asked for your goal).

  • $\begingroup$ This is the viewport layout video clip with green screen: [link] (i.paste.pics/bebc4ee835549134ca349f69ef08fd1a.png) I did the following Compositor Node setup: [link] (i.paste.pics/04a362dcec1704c219bdc202abaca49c.png) [link] It seemed to have removed the green background. I rendered the compositor setup using the OpenEXR format. Then exported it in this format. $\endgroup$

  • $\begingroup$ This format outputs a number of individual files. To import these to Blender, I used IMPORT then selected "Images as planes" ... as I could not see the option for importing OpenEXR formats. I then saw in the viewport layout a string of these files appear. [link] (i.paste.pics/04a362dcec1704c219bdc202abaca49c.png) At this point I wasn't sure what to do now. I tried the video movie clip editor .. but didn't have much luck. Those links you provided .. to me .. were not specific with this last part of trying to formalize the transparency of the video clip by removing the green screen. $\endgroup$
