The Power of Channel Booleans in DaVinci Resolve & Fusion

[@czerskip]

I love the selection of your examples which don't focus on achieving a particular visual effect but explore the technical details of the tools you show.

[@alistercarmichael4990]

I keep returning to your channel. I should stay. An excellent explanation of one of our basic tools. You are helping the jigsaw form in my mind. If only everything I did worked the same way. Coffee or not. Kettle on/off. Map kettle water to the mug hole channel. 🤔

[@clintshelton3976]

This is exactly what I was looking for! Thank you Bernd!

[@SirEdric]

Thanks for mentioning WeSuckLess! (The friendliest Fusion/Resolve Forum in the known Universe..:-)) !!!

[@firesightstudios5823]

Hello Bernd - You're so knowledgeable about DaVinci Resolve and your videos have been a great help to me, thanks for putting in the time to cover these more advanced topics!

[@JAM-h4f]

Great tutorial ! Thank you :)

[@philipoefelein6238]

Hey Bernd, thanks for another great tutorial. You've got a great teaching style -- I'll definitely check out your compositing course.

[@VFXstudy]

Thanks a lot and I am happy you are enjoying it :-)

For After Effects users the channel boolean is like the shift channels effect in ae

[@Temersson]

Once more a great study of one particular node, great stuff! Again, thank you much for your time and effort, very helpful at least for my taste!

[@MEGATestberichte]

One of the best presentations again!

[@AllThingsFilm1]

Awesome techniques! - I like this approach to Keying with the Channel Boolean node. - That technique for removing and adding back original grain is awesome. Basically, this is the best explanation of the Channel Boolean node I've seen so far. (Though I know there's more to do with it.) Thanks!!

[@VFXstudy]

Yeah, asking "What can you do with Channel Boolean?" is a bit like asking "What can you do with Math?" Not easy to give a comprehensive answer 😉

[@michaellanghausen4365]

Simon Ubsdell has many great tutorials going over the Channel Boolean as well... He also has a wonderful introduction to the Custom Tool. I look forward to watching this video...

[@VFXstudy]

@@michaellanghausen4365 agreed. His tutorials are awesome and cover a level of technical depth that is rare on KZbin!

[@TheNewton]

Channel Booleans is a great tool to exercise making a macro with or making a new default that includes premade settings for different situations. I do wish bmd made it so the settings labels could be changed or at least tied to a drop down in a macro so we could make 1 click metaboolean tools.

[@also3498]

Thanks for detailed explanation! Love the way you teach technical aspects of software! 👍🏻

[@weeliano]

This Channel Booleans node kind of reminds me of Nuke's shuffle node. A very technical but very informative explanation of how the channel booleans node work. Thank you for making this tutorial!

[@VFXstudy]

Yes, Fusion doesn't have a shuffle node by default, but I believe everything that it does can principally be done through channel booleans. You can probably find a macro that emulates the Nuke node. It does sometines look convenient in Nuke, but when looking at Nuke tutorials I often see people shuffling things around only to later do something rather simple like multiply alpha or so that I could do directly in one BOL node. So to the BOL node is enough.😀

[@deciopenna]

@@VFXstudy I was trying to understand the differences and similarities between the two. In the 3d text example you gave, how did you separate each pass to later join them again? If I understand they came from a 3d scene with lights, camera and render node and each separated pass you used was an individually 3d rendered pass and you are working on them in 2d. Is that right? I saw your tutorial about the 3d ship in the scene but in that case the model already had the different Textures. In your case It works the same?

[@VFXstudy]

@@deciopenna yes, 3d render engines can typically send out the passes separately. Also in Fusion you can create them, e.g. vis enabling or disabling certain material properties or creating passes like AO with additional tools. Yes in the Spaceship example, I am importing everything in Fusion and rendering in Fusion

[@kuunami]

And similar to shift channels in After Effects

[@kjvisual7]

I am so glad I found your channel. I will look for resources that explain how I can use math to produce various blend operations. I also look forward to checking out the forms that you suggest. Thanks.

[@ashishjatiani3356]

Can we also have a tutorial on matte control please!

[@VFXstudy]

sounds like a plan... :-) Not sure when, but I keep it in mind!

[@ashishjatiani3356]

@@VFXstudy Thanks!

[@jhuniorrdc]

perfect!!

You are so awesome!

[@johnholt702]

Hi. I hope you are well and not affected by this virus going around? do you have any coupon codes for your courses at present? Thanks in advance - John

[@VFXstudy]

Thanks, yeah so far everyone in the family is healthy which is good. Only affected by secondary stuff like the closure of the daycare etc. but guess that's a small issue considering what's going on. The compositing course is currently on a small discount until it's completed and usually I announce some short term discount via email when new stuff get's fully released. Don't have those general coupons at the moment, but I keep the courses pretty affordable overall considering the amount of work and info that goes into them :)

[@strangecasa3783]

In your groups to start with the boxes. Is one of your nodes {background}. Is it separate for the A & B Box? I couldn't figure out for over an hour why I couldn't move my boxes together and only by layer, but then I made a background node for each and it worked. I couldn't find a video where you made the boxes or to copy how they were put together. I know how to make a rectangle, text, etc. But that part just made it difficult to start for me

[@YASIR.K]

Thanks ... 🍻

[@MrMadvillan]

I have an RGB selection matte .exr from a 3d render(this is very standard) and I need to extract the red channel to use as a mask/matte. How do I do it? There is no simple answer, channel Boolean is overkill for this.

[@VFXstudy]

Not sure why channel boolean is overkill? But a bitmap node set to the red channel should also work

[@joshdiditt]

Can you do cool tutorials like Film Riot does? They just use AE and we need more cool Resolve tuts

[@VFXstudy]

Lots of "cool" tutorials out there... I focus on solid teaching 😏

[@AbrEvig]

Great tutorial as always! One little, probably unimportant question I wanted to ask; is there a specific reason for you choosing to do the paint job outside of Fusion?

[@VFXstudy]

You can do it in Fusion as well. Of course photoshop has a bit more advanced features for paint than the Fusion paint node and I was able to get it done a bit faster...

[@bbrent5340]

Hi, My God your brilliant! Hey, I noticed something I’ve been looking everywhere to find how to do and you showed it on yours. At about 13 minutes in you show your logo ‘wrapped around’ your coffee mug. It had perspective and that squished look. I’m trying to do that with an imported png company logo, wrapped around a portion of the bottle like you did on your cup. This will be a video where initially we see a beautiful sunny day video but as the scene zooms out we only see it though the logo on the bottle. When the logo is at less than full screen full screen it changes back to the factory logo color. It’s the ‘look’ of the logo that I’m not sure how to do. Oh! - is there a way to manipulate font letters in DAV16 Resolve/Fusion, like in a vector based program via the points? - say if I wanted to replicate a custom design? Thanks in advance for your brilliance!

[@VFXstudy]

Manipulate letters, you mean like completely arbitrary changes to the shape of the letter itself? Not that I'm aware of. In 2D, you could of course trace letters with polygons and manipulate those. Or get the text as a vector graphic (svg file) from an external program and manipulate those. I am not aware of a simpler solution.

[@bbrent5340]

VFXstudy Thank you Sir! As to importing an svg file, I tried that in fusion (extremely inexperienced in it!) with the import svg button and I didn’t see it...? What/how did you manipulate your logo to look so perfectly mated to your cup? - do you hv a basic fusion template for that?. I’m just experimenting/learning right. Thanks in advance Sir!

[@VFXstudy]

@@bbrent5340 I used the logo as a texture attached to a cylinder in 3d space. Then experiment with the dimensions and angle of the cylinder.

[@bbrent5340]

VFXstudy Thank you. Ok.. so use the logo as a ‘texture’? Sorry, never hv heard of this but as previously mentioned I hv basically 0 experience with Fusion. You are easily light years and about 100 lifetimes ahead of me in this regard... 🥺. I very much appreciate your thoughts regardless!

[@jkartz92]

what's the difference between channel boolean and merge node in combining 2 images?

[@VFXstudy]

Merge does foreground over background type operations, considering both qlpha channels. There's no individual channel logic inside merge. And channel boolean also doesn't do a normal merge out of the box. Replacing or adding a channel is different from doing a merge with alpha. Though it's possible to construct a merge from multiple channel booleans

[@jkartz92]

@@VFXstudy which is best advised for combing CG passes (AOV)?

[@TheNewton]

when I can't solve a fusion problem with a google search I immediately use steakunderwater search for it's forums that are a deep well of information and problem solving.
