    Full-frame overlays (transparency... but not really)

    To all,

    I have created a nifty title effect for my movie using Adobe After Effects which I wish to use at the start of my Pinnacle movie.  The title effect has a black background and white text which is simple but stunning with the features in After Effects.  I exported the title from After Effects to an .avi file and imported it to my Pinnacle 22 timeline.  My question is, "how do I 'ADD' the pixel values of this title track to my video track running behind it? The transparency tool is close, however, the background video track is dimmed by the transparency effect.  I wish the track behind (below on my timeline) to be full brightness and my title characters to display over.  Basically I want both tracks to add pixel values so that where the title track is black, the video behind is fully seen and bright.  Chromakey doesn't work since as the characters fade in and out from the After Effects track, the key loses the title characters in an uneven way and the character borders are not smooth enough.  For those users who import title animation and kinetic text, I figure this must be a simple solution I just haven't found yet in Pinnacle.

    Thanks much, 

    Greg

    Hi Greg,

    If you mean to have the black background completely transparent, then you can use the lumakeyer.

    Saby, thank you for the response.  Unfortunately, the Lumakey idea doesn't do the trick since the title fades from white to black therefore going from a luminescence I wish to show up through to black which I wish to suppress.  As the characters fade (they actually do much more than just fade), the lumakeyer changes their appearance and boundaries.  Is there not a true 'add a channel' to another in Pinnacle that allows both to show?

    Try exporting from AE as an mov file with transparency, (RGB+A). Studio should be able to recognize the alpha channel.

     P.S. If that doesn't work, google for a free AE plugin called Unmult. Apply that to your effect and it will make the black background transparent.

    Nothing like that in Studio.

    The Luma-keyer in Studio may well be able to do what you want, but you have to use a bit of "negative logic"...

    • Adjust the "Luma Center" and "Radius" controls such that only the black background part of the imported title video is opaque (if the black is very pure without too many compression artefacts that lift it above RGB 0/0/0 try "Luma Center" and "Radius" values of 5 or 10 (depending upon how "impure" the black actually is)
    • Then tick the box for "Invert Key". Now the black will be transparent and everything else will be opaque

    If all else fails In PSU22  as an alterative to Luma-keyer try Effects/Color/Shift Channels/change Alpha to Blue.

    But, as far as I understand, there is no alpha chanel in his video.
