Alpha channel layer?


If you watch the video link below, at around 1:55 min in the video they use an "Alpha channel layer" using the Auto-Trace" feature in "After Effects". How would I add one in HitFilm 4 Pro.

Or could you recreate that whole video in HitFilm and add it in your video tutorials page.



  • Forgot to mention that they where using Boris in After Effects

    In Hitfilm Pro you would also use Boris. 

    Whether in Express or Pro, to get an alpha matte from a Layer, move the layer that is the Alpha source into it's own Composite Shot. Drag this Comp into your main Comp, then add the Set Matte effect to the target layer. Select your Alpha Composite as the source layer, and set the Matte type to Alpha and Replace. 

  •  Thanks for the quick response Triem23,

    I'm pretty new to Hitfilm.

    Could you explain the process it to me step by step if you don't mind.

    One more thing I'd like to ask you... How do you create a 2D text using Boris?

    Thanks again for your help.

    Inscape Digital has a tutorial on using the Set Matte effect.
