Discover the basics of creating a powerful Color Difference Keyer in Fusion using some very simple tools. This revisits a Fusion keying tutorial I did a few years ago, but using a much simpler and more efficient method. Some useful background theory in here too.
Here is the macro: tokyo-uk.com/Motion/simpleGree...
It defaults to the Matte View so you'll need to turn that off once you're happy with your matte. There are two inputs to the Macro one for the despill path and one for the matte path - add your source green screen clip to both, but for better results you can apply colour correction to either input as required which is why I have made them separate.

I don't have fusion, but it is really good to see this and it is very interesting. Okay now back to the compositing school videos, as you linked this one for the proceedural garbage matting....thank you!

So glad you are doing more videos on Fusion Simon! Extremely interesting stuff!!!

@anthonykeith5778 4 года назад

Great example of the power of the Custom Tool and expressions. Thanks for taking the time to do these Simon, they are incredibly helpful. Hopefully more Fusion/Resolve 16 Demo's to come? :) I was beginning to worry we might have lost you to Apple Motion Demo's forever! :)

Brilliant Maestro! An elegant tool, concise "nodal-ly", comprised of simple expressions, yet in aggregate sum produce focused targeting with very little room for the introduction of user's error! (User error as in human color perception).

Thanks for this, once again. I'm not really a Resolve/Fusion user, but this is excellent, clear, and informative. And also just to let you know i've finally got round to buying the Super Glow plugin. It's great, and intuitive, just what i need to add some psychedelic looks to my first band video...

@cinema8564 4 года назад

Another of your wonderfully helpful tutorials, focusing on expressions which few others do. Love it. Here is a challenge: working on some archived film footage which seems to have the expected color shift from cyan towards red which is due to dyes that fade. But also there seems to be some red fringing along the edges of white areas. Something like the fringing that we associate with chromatic aberration. Perhaps some sort of dye aging change in highly exposed areas? Would some variant of your color difference key method serve to tackle this edge fringe effect??? Thanks again for great tutorials, Simon. Mike

Hi Mike, Thanks for your kind comment. If you'd like to send me a few frames of your original source material, I'd be happy to take a look and advise (simon@tokyo-uk.com).

@OddStuff312 3 года назад

Hi Simon, thanks for this awesome tutorial. Your custom keyer works better than delta/clean plate for me, however I still have some issues in the foreground (holes in subject). how do I a just for it? Also do you have a current link to your "custom tool mix?

@raziel4381 4 года назад

Thanks again....

@flipnap2112 2 года назад

the custom tool has such a massive array of things it can do. id love to see a tut exploring it, just for whatever it can be helpful on. ive been on Fusion for 2 years now and have done some relatively heavy comping jobs, but I ALWAYS feel like theres a ton more I DONT know. the custom tool is like that mystical node.

@SimonUbsdell 2 года назад

Yes, it's the ultimate node because it literally let's you access every single pixel in every channel of your image and apply complex transformations to it.

@TraceMistDump 4 года назад

You are so awesome. This tut really saved me for a bad lighting greenscreen project. Btw, with the custom tool, can I combine it with the clean plate technique? I'm applying on a greenscreen with many marker on it. Thank you sir and have a nice day!

@SimonUbsdell 4 года назад

Thank you. Yes, you can certainly apply the Fusion Clean Plate tool to your image path before this keyer operation and it will give good results. Unfortunately it's not really a magical solution for markers - in most cases (unless they are green) the only way of really getting rid of them is manually. Sometimes though you can chroma key the markers (or if use a standard keyer if they are green) but it still means a lot of garbage matting and fiddling to make it all work.

@morrisoc1 3 года назад

Great video! And very much simpler to follow than your other ones :) Quick question . Working on a project and the light yellow the talent is wearing is being destroyed by the despill in the delta keyer, do you have any suggestions on how to work around this and still fix the spill without affecting the original colors ? Thanks

@SimonUbsdell 3 года назад

My guess is that your "bright yellow" is more green than red and it's getting caught in the default despill assumption that if green is greater than red (or blue) it needs to be suppressed. You could maybe try building your own despill with the Custom Tool, adding this expression to the Green Channel field: if(g1-n1>r1, r1, g1). If you then very slightly increase the n1 value you should be able to keep your yellow. Of course this may well defeat the rest of your despill, depending on how brightly saturated your green screen is. Without seeing your shot I can't offer anything more useful.

@morrisoc1 3 года назад

@@SimonUbsdell Thank you so much Simon, I Really aprichate the help and getting back so fast! Excited to give it a go tomorrow! Keep up the great work on the channel 🙂

@SimonUbsdell 3 года назад

I can't promise it will work, but it's a suggestion for how to get a despill that only affects green below a certain user-selectable level (and hence may protect bright yellow). The trouble with yellow is that it's an equal mix of red and green so it can easily create problems when using a standard despill method. Despill is infinitely tricky to manage well, and there are infinite possibilities for improving on it in respect of the needs of any particular shot. The one thing that isn't possible is to offer a despill method that will work perfectly for absolutely everything. All despill is a compromise.

@morrisoc1 3 года назад

@@SimonUbsdell Agreed. That is the great thing about the knowledge your share on this channel. It allows people like myself to hit the limits of packaged keyers and understand that is not the end of the road. Just about to sit down now and give it a crack! Thanks again : ) Will report back on how it all goes.

@SimonUbsdell 3 года назад

@@morrisoc1 I forgot to mention something obvious that I am sure you will have realised, which is that you need to apply the custom despill separately from the matte extraction operation, so for example if you are using the Delta Keyer for the matte you need to take it's matte output and use that to mask the despilled source.

@dunezoop 2 года назад

Hey Simon. Amazing work... I'm completely dumbfounded by your skill level! Any idea why (at 5:31) when I enter "r2" my footage is at about 50% opacity?? It's doing my head in!

you may have missed the step at 3:20 - clip the black and white in the brightness/contrast node.

@chuotngusay 4 года назад

i have some markers in the background for camera tracking, is there anyway to clean them all or just rotoscope?

@SimonUbsdell 4 года назад

Markers are a real pain, especially if they're not green. The best approach for most of them is to garbage matte as much as possible, but it's the ones that intersect the foreground that are the biggest problem and really you just have to go in and mask them individually and with care.

@SimonUbsdell 4 года назад

can you make a 'fill green holes' feature for badly lit screens?

@SimonUbsdell 4 года назад

When you say "fill green holes", do you mean dealing with green objects in the foreground? Or are you talking about dealing with an uneven background?

@robertulrich3964 4 года назад

@@SimonUbsdell uneven bg, but I guess a contiguous feature would also fix foreground objects. photoshop has this feature called clean background

@SimonUbsdell 4 года назад

Cleaning the background and fixing holes in the foreground are two very different and opposing problems. The same solutions won't fix both, which is why I was trying to understand which particular problem you were interested in.

@SimonUbsdell 4 года назад

If it's the background that you are concerned with, then Fusion's Clean Plate is a very good way of levelling out an uneven backing. We have a much better process for this in Hawaiki Keyer but as yet it's not yet available for Resolve/Fusion.

@robertulrich3964 4 года назад

@@SimonUbsdell ok, fixing foreground then. primatte can auto remove small green splotches on actors as the mini green shapes are non-local to the background plate. i don't know how you'd do this procedurally.
