3D Keyer - Good for Green Screen? - In Depth Analysis

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.

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.

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.

Excellent work and spot on..... it works great.... Great video on this information...

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.

Still a bit confused. If someone can comment a TLDR on what I should use for uneven greenscreens and what each do best that would rock, Thanks :D

A bunch of helpful information, thank you so much for your time spent on this video.

This is great video on 3D Keyer. Thank you

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 🙏

Just amazing explanation... Brilliant....

Thanks for that - it explained 3d keying, HSL keying and delta keying great!

Immediately did not work lol

Thanks

Very good! Thank you!

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!

Danke, sehr informativ

early

I think Fusion has the best keyers in the industry. The Delta Keyer is always easy to use and provides very good results.
