This was very helpful to know and new understand the 3 options from a "quick and dirty" to get the project done, to spot on and get it right when you need it. I have been keying green screens completely wrong for the last year and now i understand how to be better. Thank you for making this video 🙏
Thanks, Bernd. A dense meal of keying full of hidden information. As usual, it proves that Fusion gives more advanced capabilities for all VFX aspects. THANKS!
Great video. Thanks for putting this together. I have more to learn about delta keyer/ fusion keying. But I would say that to get great 3D keyer results, just use ONE long squiggly line and drag it all over your video and get all of the green areas with it. That seems to work better than multiple lines in my opinion.
I tried 3 hours to key a very annoying clip of multiple products filmed in f 1.2 with focus on the product in front. Meaning the stuff in the background are very very blurry and to top it off, small objects fall from the top into the image so there is no way to garbage matt and no clean plate possible. No chance with Delta Keyer. Absurd fringe problems and no clean key. So i went to the edit page and tried the 3D keyer AND IT INSTANTLY WORKED PERFECTLY! That gave me the idea to use Delta Keyers alpha information as a simple mask to cut out the footage. Worked.
Fringe problems might be related to the inbuilt despill. Sometimes it's easier to just use the delta keyer for matte extraction and do the despill separately, e.g. with a mattecontrol node
So strange but I get much better results with 3dkeyer than Delta keyer for green screen. Right away 3dkeyer will remove the green screen immediately with a nearly perfect matte. But delta keyer seems to require a lot of fine tuning to clear the foreground and even then seems to leave gaps that 3D keyer doesn't like with fine hair edges. Not sure if I'm doing something wrong but 3DKeyer seems to work really well so I'll just stick with it.
I think both the mathematics and the interface are similar to Keylight in After Effects and Nuke, so at the minimum we can say that Fusion is on eye level - not bad given that it's part of the free Resolve version 🙂
If I want to extract smoke from a video, since it is impossible to rotoscope smoke, someone said I should try mixing multiple nodes of Keyers (Luma+primatte+difference) how would I do this? To this day I have yet to see anyone making a video on this.
Well that's tough. Where is the smoke? In front of a greenscreen? Then yes, you can try delta keyer or other keyers but it'll be quite hard. For VFX purposes white smoke is often shot against black and then a luma key should do fine.
Ok. I talk to provide background info and explain concepts rather then only show simplified solutions. The 3D keyer is a simple tool and not convincing for high end purposes. That's what I also explain in this video... I'll try to pay attention to the mouse pointer. Thanks
