How To Track ANYTHING! (Frequency Separation)

[@theDyingArts]

I'm a senior comper, 12 years with Nuke, and Ive done frequency separation for paint work for years but I'd never thought to use it for tracking. Thx for the tip.

[@AlfieVaughan]

Glad to hear it's useful! I still learn stuff all the time too. Part of the fun! 😁

[@LFPAnimations]

The ‘laplacian’ node does the same operation in one node instead of two. Learned that in my last job.

[@AlfieVaughan]

Interesting! Always something new to learn 😁

[@christoffer886]

This is the kind of tips that's needed. There are tons of VFX videos who just skips past the complexity of tracking to just show the cool stuff, but the cool stuff is mostly the easiest compared to getting a really good track. Especially since all the damn videos on tracking always shows "empty" footage without any filmed people or complex events in frame while real film footage usually has... actors.... and practical effects and stuff like that. So super advanced tracking tricks and tips are really rare to find. I hope you do even more videos on different tracking tricks for different types of situations because this was really helpful! Thanks!

[@AlfieVaughan]

Yes you're right. The examples are usually very basic 🤣 Glad you liked the video 👍

[@LaneCarter]

So dope. Love seeing stuff like this that's not a beginner tip and also a technique that's applicable to any compositing program.

[@AlfieVaughan]

Glad you liked it :)

[@twistedjourney]

Cant thank you enough on high valuable and underrated this is. Please keep them coming 🙏

[@AlfieVaughan]

Thanks! Will do :)

[@pinpointping6175]

Love when you post. Would love to see more!

[@AlfieVaughan]

Thank you! I've got a few of these planned :)

[@he.smile_]

It’s so simple and obvious I don’t know why it isn’t more common! Thanks for this great tip 🙏🏾

[@AlfieVaughan]

No problem! 🙏

[@DannyshRosli]

Hey ! Ive found a way to do this in Fusion Studio. Footage> Blur> use channel boolean instead of merge. use Footage as Background, Blur as Foreground, then, use color gain to control the Gain and Gamma.

[@AlfieVaughan]

Yep, it's a very common effect. You can do it in any software

[@Dhanuzkrish]

Moreeee tracking tutorials to come 🫠

[@AlfieVaughan]

I have a tutorial on 3D tracking too :)

[@bradmoon2483]

Great tip Alfie, thanks for that! If you haven't already done one on this I'd love to see some tips/tricks on creating depth passes in nuke when you're NOT provided one from the CG folks and have to create something using just the plate.

[@AlfieVaughan]

Thanks Brad. Glad you liked it! And thanks for the suggestion. I'll have a think about how to cover this :)

[@srmono]

What a great tip, so simple and useful. Thank for sharing 🙏

[@AlfieVaughan]

Thanks dude!

[@dudhman]

Flippin’ brilliant! Cheers Alfie, I’ll be using that.

[@AlfieVaughan]

No worries! Glad it was helpful 👍

[@artsen]

I learned something very important today.

[@AlfieVaughan]

Good!

[@ErrickJackson]

This is brilliant. Gonna be setting this up to do in Resolve for sure

[@AlfieVaughan]

Thanks :) it's a handy trick

[@MetalMeLike]

Great vid! This will help me track those pesky areas

[@AlfieVaughan]

Thanks! Glad you liked it

[@sifarathussain1335]

Its Amaizing, Really Creative workfow

[@AlfieVaughan]

Thank you!

[@ocdvfx]

he does not miss!

[@AlfieVaughan]

Hahaha 🤣 thanks! 🙏

[@viper-fx]

This is a handy technique. Thank you so much for sharing.

[@AlfieVaughan]

No problem!

[@Onn0110]

That was super helpful Alfie. Even am a Fusion user this is applicable. Would love to see if you could do a tutorial of how to remove, say, an eyebrow on a moving subject.

[@AlfieVaughan]

Thanks! I've got a tutorial on cleanup of tracking markers that would be exactly the same process as removing an eyebrow. I'd just use the transform masked node in nuke and move the bit above down over the eyebrow! kzbin.info/www/bejne/fqK0k4itl5Zpgacsi=_JFrg_FEDPZsZYGd

[@ajaynishad402]

This One so simple yet so good trick was stuck at the same issue for the skin tracking it messes up the tracker as it is almost flat , Thanks

[@AlfieVaughan]

No problem 👍

[@EricLefebvrePhotography]

A similar technioque is used to sharpen images in photography but I never considered using it to help with tracking in video ... GENIUS! I edit in DaVinci Resolve Studio but this is totally doable there as well I think. I'll test that out when I get back to my desk later. Genius.

[@AlfieVaughan]

Yep it's exactly the same process in fusion too so you'll be able to do it. It's also great for removing skin blemishes etc for beauty work as you can remove the detail, paint and then apply it back on top to restore the micro imperfections 😁

[@Zaqariyah]

so simple and so genius! Thanks a lot for this tip!

[@AlfieVaughan]

No problem !

[@cg-school]

Interesting method. Thanks.

[@AlfieVaughan]

No problem!

[@reed4109]

This was great, thanks Alfie

[@AlfieVaughan]

Glad you liked it! 👍

[@Hucklestone]

Wonderful tutorial! Thank you so much! Please make more :D

[@AlfieVaughan]

Thanks very much! I definitely will :)

[@uberjava]

If your merge's B pipe is from the non blurred plate, is it not better to use 'from' instead of 'minus'? It looks much more detailed to me. How about using freq separation with smart vectors? Would they benefit?

[@AlfieVaughan]

Either way produces a similar result. You can use both. Can't say I've ever used this for smart vectors but I'd imagine it wouldn't work very well as the dark areas of the frame where there's no detail wouldn't track properly

[@alittlestitious8856]

Good stuff

[@AlfieVaughan]

Thanks!

[@MengYUGao-j7n]

very thanks for

[@AlfieVaughan]

No problem 👍

[@fantasyzoneproduction771]

can you show face tracking , like you track your face and put iroman ?

[@AlfieVaughan]

That's just an object track in Blender. I didn't do that in Nuke :)

[@KEVS_3D_studio]

Thanks for this great info. :D Do you know if it´s possible with the same method in Blender?

[@AlfieVaughan]

Thanks! Yes it's possible in any compositor. It's exactly the same process. Just blur the image and then minus it from itself. Instead of a grade node you'll need to use something equivalent in blender like an RGB curves node to add the contrast

[@KEVS_3D_studio]

@@AlfieVaughan Thank you.! That makes sense! I appreciate your time to answer:)

[@MirceaGoia]

This seem to be like using the PixelFudger BandPass node...

[@AlfieVaughan]

Probably. It's an oldschool technique. I'm sure there's a few gizmos that have been made to do a similar thing

[@yesdadbut960]

Can you please do same with after effect !! That would be so helpful

[@AlfieVaughan]

I don't have after effects anymore I'm afraid! But it's the same process. In after effects you'd duplicate the footage, blur one of them and put it above (or below... You'd have to try both as I can't remember) and set the blending mode to minus. It'll do the same thing

[@yesdadbut960]

@@AlfieVaughan ohh thanks i didt know about blending mode mius exists i thought its a special effect for nuke thanks and please make more short tips about how to make shot more cinematic 🙂

[@KrystianMieszkowski]

[@AlfieVaughan]

🙏

[@kurokishizx]

I don't have nuke anymore haha

[@AlfieVaughan]

But there's a free version??? 👀

[@lolvonlolipopp]

hp(x,y) = sigma(x,y) - lp(x,y) g= f*hp

[@AlfieVaughan]

wh4t

[@lolvonlolipopp]

@@AlfieVaughan Just a spatial high pass filter haha. Basically, the same as you described

[@AlfieVaughan]

Oh right! How would you use it? In an expression node?

[@lolvonlolipopp]

I'm just an engineering student, I really don't use Nuke. But you would have a Gaussian kernel minus a matrix with a one in the middle, and then convolve that filter with your image. It's super redundant here.
