Supporting you on Patreon. This content is so important and you're the only one covering it in this way (as far as I know). Please keep this coming, it's fantastic.

[@AlfieVaughan]

Thanks very much for the support! There's more on the way :)

[@opti12]

He really is alive!! Super useful stuff, thanks for the early Christmas present :)

[@AlfieVaughan]

Hahaha 😂 no worries!

[@photoindra]

This is probably the best condensed video with huge amount of useful information. Thanks!

[@AlfieVaughan]

Glad you liked it 👍

[@AceSfx]

Great video mate, really informative and has helped me out a tonne!

[@AlfieVaughan]

Thanks! :)

[@luvair6765]

Thanks for a project based tutorial starting from scratch. Its weird how rare that is on youtube. I find it the easiest way to learn.

[@AlfieVaughan]

No problem!

[@syam.k.yenubari]

most underrated stuff …love the content

[@AlfieVaughan]

Thank you!

[@BlueZiFX]

thank you! I'm looking forward to the part 2

[@AlfieVaughan]

No problem! :)

[@anshulbhardwaj8337]

I needed this, because 1. I am in ur discord server and can ask questions. and 2. ur videos are the best

[@AlfieVaughan]

Glad you liked it!

[@devanu41]

Thank you sir I need learn about this

[@21stcenturyscots]

Excellent!

[@AlfieVaughan]

Thanks!

[@boringsoren]

Thank you for making these videos, I feel like nuke guides are a lot harder to find than most other software, and yours are really to the point. That aside, I was wondering how does one create shuffle nodes for all channels like at 8:46? Seems like a useful hotkey when working with multilayer

[@AlfieVaughan]

Glad you like them! That's not actually built into Nuke. It's a little python script I downloaded years ago that binds a custom script to a key and executes it when you press it. I'd link it but I can't remember where I got it 🤣

[@boringsoren]

​Oh my, I didn't expect such a quick reply on a year old video, thank you, hope you have a great day! @@AlfieVaughan

[@AlfieVaughan]

Haha! I get notifications on my phone so I reply to everything almost instantly 😁 you too!

[@HeraklionFPV]

Thank you Alfie for all the great info! One question. When you turn on the LensDistortion node for the original footage (4:50) the algorithm pulls the corners inwards to undistort it (therefore repeates the edges). And later when you apply the reverse procedure to distort the cg it pulls the corners away from the center. That means your lens has "reverse fisheye" distortion? :S

[@AlfieVaughan]

Yeah there's 2 types. Pin cushion and barrel distortion. They go in 2 different directions depending on the lens and the focal lengths

[@tacoma87x]

Use the Y normals as a mask and grade up the diffuse and spec. Use -Y and grade it down. Fake relighting that helps bring out the shapes of the car.

[@AlfieVaughan]

Good tip but I didn't include stuff like that because this is just a basics video!

[@macIain]

Any chance you can show us how to prepare renders in blender for nuke. For instance the car by itself with the transparent background.

[@AlfieVaughan]

I have a video on how I render stuff in blender. It's slightly outdated now but still covers the concepts you're after kzbin.info/www/bejne/iIKqg4yji9CcsNEsi=sgD6P8pc1-XtsAF9

[@chrisalldridge1235]

I've rewatched this a few times and followed along with the project files - I reiterate my previous point - it's fantastic... (For anyone watching, the 1 dollar Patreon subscription is well worth it - you'll learn a bunch from following along!) I wondered whether you might consider doing a set of videos along this same "nuke for noobs" style where you take some basic footage, track it in Nuke then export to Blender to build out some CG elements and then bring it back into new for some compositing work. -I'd be particularly interested in a breakdown of how you prepare the files for export in Blender (e.g. mist pass/ render layers/ cryptomattes, etc). -- Apologies if there are videos that already cover this (I'd really appreciate a link if so!). Let me know if there's anything else I could do to support this idea/your tutorials & have a very merry Xmas!

[@AlfieVaughan]

Glad you've been finding it useful! I'm currently working on a blender VFX course that is being released soon and is what you're describing. Unfortunately I'm contractually obligated to not release anything too similar to that on my channel otherwise it will make the course fairly redundant. I'll keep you posted on it :) Merry Christmas to you too!

[@chrisalldridge1235]

@@AlfieVaughan Fantastic! I look forward to it :)

[@relaxmusic77]

Hi, thanks for this very useful content. Have a question, why do you use the blender mist pass instead of the blender Z pass for defocusing ?

[@AlfieVaughan]

No problem! The mist pass is actually what the depth pass would be in other software. For some reason blender's "depth" pass isn't anti aliased so it won't line up with your beauty renders if you use it

[@relaxmusic77]

@@AlfieVaughan Oh i see, thank you for your answer !

[@itsvishnu6969]

Hey.can we add a cg object in a video has no camera movement in nuke?

[@AlfieVaughan]

If there's no camera movement you don't need to do any tracking. Just manually line up the camera on one frame and then it's done

[@botondben]

Thanks for the tutorial Alfie! I do have some questions though. 05:45 Is there a way to merge the A side (which is larger size) to the B side without having the merge node align the larger image to the lower left. Insted I would need to align both images just to the center. I guess this is one of the reasons you are using that CC/grade node instead of merge. I am in a situation where I have to precisely placing the CG on to the footage, with lens distortion of course.í 03:06 The Reformat version has the bounding box at 1968x1135, which is a bit smaller than your original render. Why is that? Thanks! :)

[@AlfieVaughan]

Yep you have to add a reformat node under the larger image with the format of the background image (in this case HD) and set the resize type to none so it scales from the centre instead of the bottom left. Then they should overlay how you want

[@botondben]

@@AlfieVaughan Thanks for the quick reply! Appreciate that!

[@teeambird2079]

Is it recommended to only use openEXR file format to get all the render layers and passes for comping or is there anything lighter? I'm just imagining trying to do that with 4K frames and running out of drive space very quickly :/ I feel like I need a good proxy workflow to achieve what I want in Nuke with my storage/processing limitations

[@AlfieVaughan]

There aren't any others sadly. EXRs are the only format that support so many channels. There are different compression levels you can set to help with the amount of space they take up. Although some passes like cryptomattes can't be compressed or they break

[@narendra672]

👍

[@PostolPost]

What tool are you using at 13:35, is that some script or smth? Like W hotbox, but I can't get

[@AlfieVaughan]

It's called channelhotbox. It's on nukepedia :)

@@AlfieVaughan got it, thank you!

[@sansidiakite3982]

Hi..! I would like to know how to use vector motion blur from blender to nuke thank you.

[@AlfieVaughan]

There's a node in nuke called vector blur that can read the channel with the vectors in

[@sansidiakite3982]

@@AlfieVaughan I tried several times but unfortunately it didn't work. can you make a video or send me a link on it thank you

[@henriribeiro8795]

Did you tracked and rendered the car in Blender?

[@AlfieVaughan]

There's no tracking as it's just 1 frame. I used fspy to align the camera. But yes it's render in cycles in blender

[@subhayanbose9191]

In what file format you're rendering the render passes??

[@AlfieVaughan]

OpenEXR multilayer :)

[@subhayanbose9191]

@@AlfieVaughan man I'm currently working on a project and its taking ages to render in exr format... I've a low end pc ofcourse

[@subhayanbose9191]

Can you tell me if I render in some other format like tiff then will there be a problem such as loss of data

[@AlfieVaughan]

Tiff files can't contain all the extra channels so you'd only have RGB. You'd have to render every single AOV as a separate tiff sequence

[@RedFarol]

Why dont add grain into the car?

[@AlfieVaughan]

My camera is so good in low light that there's very rarely any noise in the footage at all. I tend to add some film grain to the whole picture overall when colour grading but not in comp unless there's noticeably present noise in the shot. Different story at work. I always regrain CG normally as the cameras like the Alexa have a lot more natural noise
