But i really like fxphd tutorials (not sure if they have basic introduction to Nuke) digital tutors have tutorials for sure. Where to start? For the beginning tutorials i'd say almost anywhere. My advice to you is "watch tutorials" watch watch and watch! Don't need to remember everything, it's enough to remember pieces, so when you are faced with a real life problem, chances are you will remember that in a tutorial some guy did something similar, you will look it up and get the job done that way. I'd say stay for 1/1.5 years as prep artist and than try and get in the comp department. I'd recommend you to look for a job as prep artist (to learn roto and paint first) It's easier to get in and the learning curve as well - also this will give you solid foundation for the future position you are after as compositor. Working alone is much much slower to advance if you don't study, cause there is so much stuff to learn and you will continue learning till the end. Also when you get a job as VFX artist, if you want to improve and climb up you will have to invest more after work, watch tutorials and more tutorials, work on side projects and learn some more. when there is a project usually you will have to do lots of overtime. Also be prepared for the crunching hours. Do you like to settle down soon? Cause VFX won't give you that, on the contrary. but other aspects are more important to make the decision to get in the VFX world. I started at 26 and no it's not late at all.
