I really like the 5 min tutorial concept. it becomes very practical and useful during busy work day with artists, producers and clients. whatever the topic is. Per the Colouredge and Anti-aliasing it's the first time someone is addressing this issue in a tutorial So many thanks. I never miss any of your tutorials.

[@HugosDesk]

+Lior Weiss Thanks so much fro the Kind words. Yes this started because people complained about my 90 min long FXPHD classes, lol. So I am promising always 5 min, but will try at least to be less then 7-8. Thanks again

[@HenrikDoark]

Hugo, how amazing was that your mini class! Several years that I watch videos of DT, FXPHD, YT and never explained to me how to normalize the depth and / or fix the artifacts! Thank you very much! :D

[@HugosDesk]

+Henrik D'park Thanks so much for the kind words. This technique will not work if the Objects cross over too much. For that I use this and some Edge Blurs with Object ID's and sometimes a few stroke of paint. But that is another video for another time.

[@haaake]

Great information. You can also just use the raw depth data in the zDefocus node setting the math to "depth". You don't have to normalize the depth unless you need it for some other purpose. You can also use the Filter Erode to expand the depth channel to fix the rough edges that don't properly overlap the anti-aliased alpha.

[@HugosDesk]

The only reason I normalize is so I can have a visual representation of where the Z-depth is. This way I can adjust Edge Extensions, Edge Blurs, Filters using IDS, etc. I just prefer to see it so I can locate where the problems are. Having said that, this video is now almost 4 years old. These days I just use Deep information to solve some of these issues, to be honest.

[@Michael-yf6pj]

Thank you very much! It is a question that I have been puzzled for a long time!

[@HugosDesk]

No problem, glad I could help.

[@Cimpy101]

You rock. Thank you so much for this. I was trying to tweak the depth values in maya. This is just what I needed.

[@HugosDesk]

Glad to help. Thanks for watching

HUGO !!!!! I have been struggling with this for ageeeeeessss ! Wow ! So happy to see someone treat and solve this issue ! And all that in 5 minutes.... What else...... ;) You da man Hugo ! Keep it up ! Oh by the way, do you know how you could get this to work in After Effects by any chance ? I know you don't really use it anymore but sometimes we just don't have the luxury to be Nukin' around soooooo ;) Would be greatly appreciated ! Till soon ! Take care ! THANKS A MILLLLLLLL !

[@AFaria8]

Thanks for the video Hugo, really nice and helpful. and thanks for providing the source files too. looking forward to the next ones :)

[@HugosDesk]

+Anabela Faria Not a problem, glad you liked the video. Cheers

Love it, cant wait for more. No crap, long, boring tutorials anymore

[@HugosDesk]

I try making it as short as possible and to the point. It is hard but I will keep trying.

Really appreciate your tutorials! Have you composited with passes from Unreal Engine? Im trying to follow what you are doing here but the passes from UE look a little different.

[@HugosDesk]

Unfortunately not yet, but I will soon!

[@rr_10102]

Short and sweet. Thanks for the very useful tip!

[@justKolia]

Thank you very much Hugo! It is really cool! I like it! And i think it is not so important to get in 5 minutes range. Because sometimes is difficult to explain something in a 5 minutes. And it will get more then 5 but less then 7 or even 10. It is a quick format too! I wont be upset if your quick tut get 10 minutes. ))) Thank you sharing your knowledge and your huge experience! I really appreciate it and i think im not only one. Keep going! Looking forward your new tuts!

[@HugosDesk]

+justKolia Thanks so much of the kind words mate. And yes sometimes it will be 5, 6 or 7 min. I just want to make sure it is short and one topic or node only. Easier to share and to watch. Thanks again.

[@Emm_R_Guitar]

This is a great idea. The edge thing has always thrown me with zdepth. (student) What is the difference between the Nukepedia node, and copying the alpha and eroding it or dilating a few pixels? Just wondering.

[@HugosDesk]

Thanks for the kind words. Yes you can do it manually without gizmos but I just find it easier to use the pre-made nodes. But there are many ways of getting the same result. Cheers and thanks for watching.

[@rikinpatelvfs]

Hi Hugo. Once again, great tutorial. Very helpful to a lot of us. But I have a question for you. I was working on something similar and getting the same artifacts, but in my case the 3d geo was overlapping and the edge of the foreground object was off by a few pixel (with depth pass). As objects were overlapping, I couldn't do edge extend. Hope it makes sense. How would you approach to this problem? Thanks in advance!

have you found the solution?

A huge help. Thank you, Hugo.

[@MaDiViL696]

Really cool video ! I just have a question, i have an animate and i would like to have my focus first on the FG and then defocus to the BG, and i some issues doing it. even if i animate the focus place. Is there anything to be carefull about ?

[@RajuMon2016]

Hugo you make my life easy thanks

[@GHOSTPIXEL95]

Hey man great tutorial! I was wondering where can I find the Edge Colour gizmo it seems to be deleted from everywhere, I dont know why L( plz help!

[@haaake]

You can also just use the Filter Erode to expand the depth channel by +1 or so to expand it to properly cover the alpha. Put the FilterErode into your depth channel stream, set channels to "depth.Z" and +1 or so should work fine.

[@danielefrontini6204]

Thanks Hugo!

[@HugosDesk]

No Problem

[@mindsteamers]

Great tutorial! Could you show us something about using deep composite?

[@HugosDesk]

+mindsteamers Yes maybe another time, sure. I will added to the list. Thanks so much for watching.

[@Pinionistus]

+Hugo's Desk yeah hardcore deep compositing is my next stop on my learning curve 😊

[@talesbyfirelight3728]

Hey Hugo! great vid. The values in your Depth pass are in the thousands. 3108 for black point and 1873 for white point. The Depth pass I'm testing out here from my client is 1.09000 at it highest and .55000 at its lowest. And its backwards. The closest part is darker and farthest point is brighter. Any thoughts?

[@HugosDesk]

Not sure about those values. Are you clamping or limiting the values in 3D? The values should match 3D coordinates and distances camera so if your 3D is made to corrects scales it should be a lot higher.

[@mixjix]

I'm having the same problem, did you manage to resolve this?

[@HugosDesk]

You need to make sure you have correct values in the Zdepth settings in 3D. Also you need a proper scale in your 3D scene. Maybe that could be the problem?

[@mixjix]

@@HugosDesk I'm new to Nuke, but turns out your workflow works for me, I for some reason have to use decimal values from 0-1 (0.XXXX) instead. Will look into your suggestion though, thanks.

[@Alexandremetalhead]

Hugo, obrigado por compartilhar conhecimento. E quanto aos tutoriais em português, você ainda pretende faze-los? Grande abraço e sucesso para você.

[@HugosDesk]

+Alexandre Rufino Obrigado. Achas que existe muito gente que gostaria de ver em Português? Achas que sim? Eu posso fazer Dub a este e ver se tem muitos "views"

[@Alexandremetalhead]

+Hugo, eu acho que sim. Existe um canal chamado Borgo TV, do Magno Borgo. Todos os seus vídeos são em português, e acho que tem uma comunidade grande e muito carente de tutoriais em nossa língua. Seria ótimo se você fizesse tutoriais em português, já que você é um dos grande nomes da composição digital :)

[@AndreiBoscoBR]

+Hugo's Desk Também acho que seria bem interessante vídeos sobre composição e nuke em português.

[@blackswann]

Hey Hugo! Is there a way to fix the edges of this character if she was rendered out as part of the background and not a foreground element? I’m running into edge problems on a scene with lots of leaves and grass - when trying to apply depth of field on the whole scene in Nuke I get edge artifacts in between leaves - any way around this in Nuke or would you need to render DoF in camera in 3D?

[@HugosDesk]

Only way to go around this is to use Deep compositing and PGBokeh. Everything else will have edge issues. Last resort would be DOF in 3D

[@blackswann]

Hugo's Desk thank you for quick reply! Loved your deep compositing process video - will have to try this out.

[@9177852573]

Good one! thanks

[@zsmithcreative9519]

ColorEdge & EdgeExtend remove from nukepedia any any suggestion how to find out this 2 gizmos...?

You can do the same with Nuke 12's new Edge extend node! The new node is GPU accelerated. But if you the old ones want here you go: www.dropbox.com/s/qs8fhzp594w7u25/Archive.zip?dl=0

[@HugosDesk]

+Cyan Tarek Thanks so much

[@Advection357]

Is there a way to get a "Y depth" from a renderer? As in points close to camera's height are black and farthest upwards are white... so just an axis change. Maybe something can be done with the position pass? It's for an atmospheric effect I'm trying to build in post & want to avoid rendering large scalar field volumes :3 Search brings up nothing...

[@morrisabramian2276]

this can be created while rendering, a falloff map based on camera Y axis

[@apmanti12]

hey hugo, can you explain on how to use curve tool to find depth?

Hey Hugo! Do you know if there is a way to link the focal point attribute to a tracker? It seems that Nuke won't let me do it...

[@WiseHoax_ArijitDatta]

I have a render but which has no alpha channel because its a ground shot .then what to do??

[@monocore]

Awesome

[@HugosDesk]

Thanks. Need to make a new version, this is like 4 years old already.

[@monocore]

Hugo's Desk that would be great. I just moved from AE to Nuke and I found your videos super helpful. The logic is exactly the same I just need to work my way through the right nodes. And the edges problem in depth is old as time itself. I used to render the depth pass 4x times the resolution but that is no longer suitable. I’m having trouble with overlapping foreground de focused objects, but I guess that’s just a limitation of the technique perhaps? Anyway, big thanks and keep it up!

[@dysnXO]

Any idea how to fix this in After Effects?
