OT: Boris

Hi everyone

This is a bit off topic but with so many knowledgable people I am hoping someone can help me. I am using Boris Grafitti to generate some lower third titles for a project in Vegas. So, I start the Boris key framer and create a simple text layer with no other backgrounds. When I check the alpha channel all looks good. I export this as an AVI file making sure that the Alpha option in the export for Alpha is set to straight.

However, when I import this into Vegas there is no alpha channel and I have my text but everything else is black so the underlying video will not show through.

Can anyone tell me what may be going on here. I know I can do all of my titles in Vegas but I am thinking of buying Boris Red and wanted to see how the basic grafitti package worked.

I am sure I am doing something silly but I can't see what .

Any help greatly appreciated

Allan

I'm a little confused on what you're trying to do. Are you using Boris as a filter inside Vegas, or as a stand alone engine (not sure if Graffitti has that, but Red definitely does).
Anyway, if everything looks good in Boris then make sure inside it that the alpha setting is set to 'premultiplied black'. Then in Vegas right click the clip from Boris and select prpoerties-media, then make sure the alpha there is set to 'premultiplied'.
Boris is a little tricky and you'll probably need to get Chris V's dvd to get started. It can do some cool things, but I still consider it's integration with Vegas is ify (sp?).

Did you have the "checkerboard" backgroung going on in Boris before you tried exporting?

I called Boris support once for Red 3.0 and was told to first UNCLICK visibilty eye icon on any underlying layers (mine defaults with a black layer background) so I have just the TEXT/Lower Third layer with the usual Transparent-indicating CHECKERED background THEN I was told to export as a QT .MOV file (not AVI) and be sure to use the "Millons of Color+"
setting for colors (for 32 bit as opposed to 24bit) for transparency. Imports into vegas nicely , making sure I have all quality related settings to THE absolute best, looks great.

oh and be SURE to click on the event you important and change the alpha thing to let Vegas know it has transparency, I just export as STRAIGHT from Boris and set it to STRAIGHT within Vegas
