  3. Daniel Says:

    could you make this in fusion also, please

  4. Kert Gartner (VFX Haiku Admin) Says:

    Hi Daniel,

    Is there some specific aspect of the tutorial you’d like to see in fusion? There’s a few techniques that are already covered in other tutorials (such as keying and and edge blur)

  5. Michael Jones Says:

  7. Amr Says:

    thanks so much for this tutorial…really appreciated
    i use both AE and fusion
    but i’m new to fusion and i downloaded the project files and tried to apply this tutorial in fusion and the problem is fusion doesn’t wanna load the quicktime file
    in the assets folder though it works perfectly on AE
    is there’s any reason for that???

  8. Kert Gartner (VFX Haiku Admin) Says:

    Is this on the same machine? There shouldn’t be any reason fusion can’t load it. Try loading the clip into a new loader and see if that helps.


  9. Amr Says:

    thanks for the reply
    yea it’s on the same machine and btw my os is windows 7 64 bit, does that make a difference??…
    i tried loading it again into a new loader but still nothing happens

    another question if u don’t mind i was wondering how i can track rotation and scale in fusion tracker??

  10. Kert Gartner (VFX Haiku Admin) Says:

    Hey Amr,

    Yup, Fusion doesn’t support Quicktime in windows 64. It’s a bit of a pain. As for tracking scale and rotation, you have to have multiple tracks in your tracker in order to do that.

  11. Amr Says:

    well, thanks for ur help man.
    i will try to convert that file to another format then…

  12. lex Says:

    Hi! great!
    Is it too much harder do do this with fusion or combustion? (it will be cool if you posted a complete fusion tot not just “some specific aspect of the tutorial you’d like to see in fusion?”).

    Seeing that you seem to prefer nodes, but posted this for after effects…

    these tutorials rock! keep ‘em up… these are great for someone who knows software (and other CS apps) but not motion graphics- well done!

  14. Patrick Says:

    Very nice tut. I liked the trick to matte the edges alot! But there´s just one tiny fault: The sky shouldn´t scale up. :)


  15. Kert Gartner (VFX Haiku Admin) Says:

    Nice catch! You’re totally right! :) It only scales a slight amount in this shot, but you’re right, that as a general rule, it should not scale at all. :)

  16. Patrick Letourneau Says:

    The Find Edges bit saved my ass at work today. Fantastic tutorial, Kert!

  17. Jhon Says:

    Please make this in Nuke..I am looking for one but I can’t find anywhere

  18. Kert Gartner (VFX Haiku Admin) Says:

    It shouldn’t be that hard to apply the techniques from this video from AE to Nuke. In any case, I’ll make one for nuke as well, that’s a good idea :)

  19. Novel Says:

    Thnx a lot for great lesson!
    But AE so fu**ing complicated comparing to Nuke and Fusion %)

  20. Elliot Says:

    Thank you SO MUCH! :D You are the best!

  21. Able Says:
