I love the initiative, and i'm super happy you want to help your audience comp your elements the best way possible. But there are a lot of mistakes in this video that i feel i cannot just leave unremarked, cause i want people to learn the best practices when it comes to comping in nuke. Some are rather small and not so important, like small problems with how the order of operations happens. F.ex you always want to colorcorrect footage or elements before you give it a filter kick using a transform or reformat. You should always grade your footage before transforms. I hope this doesn't come across as some stupid keyboard warrior or anything, i genuinely just want to spread awareness of how to improve this and work correctly. So here's a list of things i saw. 1) There's no point in reformatting the fire element if you are going to transform it to be even smaller in the plate anyway. The reformat will concatenate with your transform nodes scale and is therefore redundant. But its good practice to put a reformat that matches the format of your B-pipe set to resize type: none, and uncheck center, so you can connect your viewer to the reformat before it enders the merge and be able to look at the element placed correctly in the format, but against black :) 2) Teaching people to merge A from the right like you do is a bad practice :) The mask input is on the right by default, so A should ideally merge from the left, this makes larger nuke scripts a lot easier to read without zooming in on the nodes, and is just a good habit to have, its not a big deal of course unless you share scripts with other artists, but its a good practice :) 3) I would recommend avoiding the built in glow in nuke, when its so easy to make a exponential glow yourself by stacking blurs (its easy to find tutorials for this), but more imporantly, when adding a glow to you comp that should always be added using a plus operation, never a screen. "A+B-AB if A or B ≤1, otherwise max(A,B). In other words, if A or B is less than or equal to 1, the screen algorithm is used, otherwise max is chosen. Screen resembles plus. It can be useful for combining mattes" its useful if you want to combine mattes, but it will clamp your glow to either the max values of either A or B or it will clamp it to 1.0, which is not how light works, and it will look wrong if you are using HDR values. The Glow node in nuke also does not play correctly with HDR values, so i highly recommend not using it. 4) The fire should be added as an over operation, and then the glow should be merged below that as a plus . The reasoning behind this is that fire is essentially soot which is black, which is extremely warm, leading to black bodyradiation on the outside leading to the warm fire colors. But the soot is not see-through. And therefore it should have an alpha channel and be merged as an over as it occludes whatever is behind it. 5) When you comp the smoke you seem to mix up the premult and unpremult, You should unpremult first, then premult. 6) The smoke should also always be merged as an over since it should occlude what ever is behind it (since smoke is small particles that you cannot see through), and you should unpremult your footage, then grade the alpha down and then premult again. This way you don't affect the colors, but you affect how dense the smoke is (in terms of opacity by changing the alpha channel). I hope this is of use and that its not taken as being mean, but rather the constructive criticism its meant to be :)
I'm from India,in TAMILNADU.hi bro ur tutorial is clear and detail easy understanding with learning in ur tutorial video pls keep it and continue bro😊.and small request bro, pls explain and upload how to do complicated shot of keying and camera tracking tutorial.

great, but it would be cool to see how to comp fire in the day-time scenario as it is very different from night-time
Bad joke, but I have to say it...that tutorial was fire! 🔥🤣
Great joke lol 🔥
it is a good joke
the cracked after effect
Love it! It looks awesome. Thanks!
Glad you like it!
Great video thanks! can you make a compositing blood or fog? :)
WONDERFUL
Glad it was helpful!

You are so welcome!

Can you composite Gas Explosions?
Good lesson, thanks
Love it! I need to hire an effects guy. I do indie films. Do you work for ActionVFX?
We're open to collaborations however the best place to find VFX artists is our discord:

Wow!!
Pls the tutorial on How to turn into Hulk😲😱
But how did he stick all elements to car 🤔
hello please Can you provide the footage ?
We should like see the tutorial in FUSION, because NuKe is a Software very very expensive and Fusion is more affordable...
Nuke non commercial is free
@@BraineZVisuals on the one hand you are right, but there are many important tool that is not included when it is free
Can you provide the input please
so simple 😬
Where is nuke file
guys where can i get adobe after effect for free
at your nearest jail
@@EzDyt😂😂
Where is the work file
Here it is!
