Hi, i am trying to get rid of the  black background of a file i imported from Hitfilm Pro into After Effects with transparency. I have looked on the web and tried a few things like  Blend Modes, Shift Channels, Linear color key etc, but nothing seems to work. Do any of you guys have any ideas?. Just finding my way here.

You are probably looking for some kind of procedural matte. Some stock clips have a black and white copy that can be used as a track matte. 

 

Without seeing the actual shot it is pretty hard to suggest an efficient workflow. If you can embed a screenshot or link to the video we can probably point you in the right direction. I have about 40 different workflows that I use on different kinds of shots.

Hi Rick, it is just a ground fire effect that has transparency, but turns up in AE with a black background
