    fire edge keying

    Posted by Nick Chambers on November 2, 2011 at 9:20 pm

    Hey,

    Was wondering if anyone had any pointers, ticks/tips and or ideas for keying / edge bleeding.

    I have some fire premultiplied and rendered on orange although the edge is still quite dark. I am looking for a technique to remove the edge bleeding.

    I have tried general colour keying etc but the base of the base of the fire is similar to the edge bleed.

    Cheers

    Use Levels and set its Channel to Alpha Mode. Then crank up the Input Black values to suit your requirements.

    Also don’t forget the free Unmult plugin. Could be helpful.
