    Thank you for this very clear explanation. Finally understood! :]

    The natural thing to try if you don't know about premulting is to use the alpha channel as a mask in the grade node.
    What is the difference, what happens and why is that wrong?

    on 6:38, I followed the steps up to the point where the dragon appears, but for some reason, I cannot get my object to appear with the background without having both stand out than the other. How can I fix this issue?

    The other tutorial simply adds a "premult". Is that sufficient? And how do you disable a node?

      VFX Ltd™ Toggling the "d" key will disable/enable a selected (or multiple selected) node(s). On a side note; I agree with Greg Piekarski, push through and learn Nuke if you can. It is extremely powerful, especially in VFX.

      Eric Walters Thanks. Learning the basics at the moment! Even the basics are complicated such as motion tracking! :)

      VFX Ltd™ even more funny thing is that no one use AE any more so if you think about VFX industry better start to learn NUKE
