How to Green Screen in Fusion (Davinci Resolve) 

Glad it was helpful!

So happy you found it helpful! 😄

Glad to help!

The background is just a single frame from a video I filmed previously. You can source your background however you like. Can be an image or a video. Mine was an image and I just dragged it down from the media pool. It created 'MediaIn2' which acts the same as the footage we're working with which is 'MediaIn1'. Both pieces of media get combined with the merge node. Hope that makes sense.

@@ChaylonCo Thanks. That cleared it up. Appreciate your quick response …Rowby.

Thanks! More in the works

You're very kind. Hopefully more coming soonTM

Thanks! Yeah the resolution is set by the background. If you know a way to change this let me know.

@@ChaylonCo Insert RESIZE node between background and MERGE node :-)

Great tip 😊 I need to be better with keyboard shortcuts

Make sure you're previewing the clean plate in the monitor. I talk about how to make sure you're looking at the right node in the video.

Thanks ☺️

Your FPS should match your background footage. If you’re deciding both then it’s a project decision. What do you want it to look like? The slower the FPS the more motion blur which can be harder to get a clean key on but still possible so I wouldn’t let that be the decider. I’m usually shooting for corporate clients who want it to look clean and professional so I’ll go for 30fps with a faster shutter angle like 135 degrees. (Just watch out for flicker) If I was filming for something more creative I would still film in 24fps and 180 degree shutter but would need to really make sure the green screen is well lit otherwise the increased motion blur could make things harder. Hope that helps, thanks for the like and subscribe :)

@@ChaylonCo​​⁠Thank you for taking your time to respond with all that. I’m shooting a some green screen stuff with my kid and the background is just an image. I think I’ve got a solid mask selected for her and I, but I’m dealing with some annoying flicker on our body’s edges. I’ll work on your suggestions and maybe trying some better lighting. Again, thank you!

Sounds like camera noise, try applying a denoise to the footage first. I’m not sure if you can apply denoise before you key in Fusion so what I’ve done before is applied denoise and export the whole shot and then brought it back in and applied the key

No worries!

It's never been easier 😄

Thank you 🙏
