this guy makes some really good comp tutorial he is mid comp with 5 yrs of experience check out his courses. https://www.udemy.com/course/introduction-to-nuke-compositing-nk101/

and this guy is senior comp Uk he has some really really good pro level tutorials as well

also see if you get a mentor it will faster the overall process and help you cut the crap and avoid unwanted bad practices and tips. Goodluck.

So I made this with the Udemy courses of u/GreenScreen20

This is the final project you end up doing in his Nuke 101 course. I did it slightly different to how he did it and chose to make the hologram element itself in AE as motion graphics are easier for me on there. I didn’t use a lot of the final tutorials to make this comp in particular as I wanted to see what I could achieve on my own but the education he gives you throughout the course is clear and has examples to back it up.

The footage featured is also in other courses, I think it’s quite commonly used in VFX tutorials, but this is from this course in particular.

I also highly recommend Paul DeNigris’ tutorials on keying. This one in particular is a gem and helped me a lot with this shot.

I would highly recommend anyone starting out in Nuke to learn from these people and just test out comps and be creative :)
