You are a legend, this was the best beginner tracking tutorial I have come across. Thanks you so much.

[@PDeNigris]

Oh thanks!! I appreciate that!

[@rhettpeter83]

its like vandalism without the vandalism

TeacNice tutorialng is your talent!

[@AllThingsFilm1]

Another awesome tutorial. I loved the high-pass setup for improved tracking. I'm using it in my pro work, now.

[@PDeNigris]

Since this tutorial, I've learned that the Laplacian node does the high-pass in a single node.

[@razmeback]

very helpful, good amount of extra details covered without rambling, thank you very much

[@tanminh3152]

showed, how do I fix tNice tutorials? I followed exactly what you did.

[@davidbrown6494]

Thanks for the great tutorial. Only one comment I'd make, the "filter" option (both in the tracker's transform tab, and in the tracker) controls what filter is used when mapping 2d points to new locations. It doesn't affect the tracked points (which is why it doesn't improve anything related to the jitter). The Mitchell filter can be useful with high-contrast images (such as the checkerboard) as it blurs the image slightly.

[@PDeNigris]

Right you are sir. I have learned quite a bit in the 4 years since I posted this.

[@davidbrown6494]

@@PDeNigris There is definitely a lot to learn in Nuke. BTW, the "filter" that I think you were wanting is a little higher up in the transform tab, smooth, with r t and s options.

[@ThePoisonedArtist]

So I'm trying to remove multiple markers on a plate, am I obligated to do multiple tracker nodes and multiples rotopaint nodes or can I do it all with two nodes? And how would it work? I tried doing multiple nodes but I can't even merge them together

[@PDeNigris]

Good question. It's going to entirely depend on the camera movement and if the trackers are all in the same plane relative to the camera. In my video if I had multiple spots on the wall that needed to be painted, they wouldn't be in the same plane relative to camera because I'm coming at the wall from an angle, Which means yes I would probably do multiple trackers, each one driving a rotopaint node. And as far as combining rotopaint nodes, you can stack them one after the other in the same pipe, no need to merge. Now if I were shooting the wall straight-on, then I could probably get away with a tracker that has 2 track points - one for Translate and the other for Rotation and Scale - and use that to drive a single rotopaint node. But I find you get a bit of drift on your paint strokes in that scenario so I generally do option 1 above. Hope that helps!

[@somiel7208]

Hey can you tell what is use of Tracker in Rotopaint node

[@carinnagarcia2301]

Thank you for sharing the assets!

Sir plz make a video on matte painting on nuke and photo shop

[@snweddings9790]

great tutorial from great vfx artist , thank you

[@PDeNigris]

Thank you!!!!

[@ricardowesker9423]

maybe is too late, but your problems with the track is for the automatic stabilization of your phone.

[@PDeNigris]

Entirely possible.

[@jaykay789]

Just what I needed. Cheers for the 411 :)

[@Wheel333]

Nice way to legally try out your artwork in different locations. Thanks for these.

[@artista3d205]

I CONECT THE ROTO PAINT ON TRACK AND THE ROTO PAINT ONLY WORK FRIST FRAME,AFTER DONT WORK WHY?

[@PDeNigris]

Your stroke lifetime is set to 1 frame. Needs to be set to all frames.

[@artista3d205]

i did it,but after dont follow,i fooled all you did but doont work similar,my nuke is v 12.i am trying by this why remove a woman in video and the woman is stoped and only move the head and the fontage only move the camera.frist i do the rotopaint and after the camera track or this dont mind?

[@PDeNigris]

@artista3d205 really hard to say without seeing your Nuke script

[@artista3d205]

ok,thank you for attention

[@artista3d205]

if you dont mind i can send the fontage by email if you offer to me the email and you see the fontage and check

[@scarabrae]

Nice tutorial, Paul.

[@PDeNigris]

Many thanks!

[@arjunmk8034]

Nice tutorial 😊😊👌👌👍

[@norrinradd1979]

Brilliant lesson, thanks dude, went through this today at school but this really solidified the soup in my head !😀

[@PDeNigris]

Super glad you found this helpful!

[@VictoriaFilmsgroup]

question: if the wall had been plane, with no intersections or anything could you still create points to track?

[@PDeNigris]

It would entirely depend on the texture of the wall in that case. If the wall were smooth (like drywall for example) then you'd probably need tracking markers (little tape crosses or dots on the wall during shooting). However I have definitely tracked shots where no one thought to put markers up. Sometimes you have to put in a bit of elbow grease!

[@VictoriaFilmsgroup]

Paul DeNigris thanks for the answer. That was the reason why i was asking: sometimes you may not of putting markers during the shoot so i was wonderong if there was still a way to work it out without.

[@PDeNigris]

Yup, the high pass technique I demo in this tutorial can bring out a surprising amount of trackable details in even "smooth" surfaces. I've started doing it as SOP anytime I have a difficult track.

[@VictoriaFilmsgroup]

Paul DeNigris good to know. Thanks again.
