sony vegas 10 alpha channel
I bought some stock fire & flame footage with black background . They are .mov files . Is there any way to add an alpha channel to these files ? I’d like to bring them into Vegas , open properties , select alpha & have the black background be gone.

You can try to key out the black, Vegas keyer might not be able to pull it off but Ultra Key might. If you don’t have access to Ultra, you can post one of the videos on Vimeo and for non premium Vimeo members, they allow the original file to be downloaded for a week I think. That’s one way around the ten meg limit for most eamil services. I can see if Ultra can do it for you. Danny Hays

I can key it out in Vegas with fair results . I was hoping there was a way to convert (add an alpha channel) the original mov file . Then when I bring it into the project & r click the file , choose properties & select straight in the alpha channel drop down.

Danny , ended up rendering clip as rgb , brought it into Vegas & selected field order -none , alpha channel -premultiplied & it worked . Thanks for your ideas

Then they had to have a transparent alpha channel already. Cool!

Guess I spoke too soon . Tried this method on 2 other similar pieces of stock footage & it didn’t work . Any other tips ?

If any of the clips are 10 meg or less, email me one and I’ll see what I can do for you. Danny Hays
