After you import the footage in vegas….you go to the
“project media” tab and right click the particular footage
and select “properties”. When that comes up you see at the
bottom, “alpha channel” you then change it from “none” to
“straight (unmatted)”.
Now when you drag the footage to the timeline, the alpha
channel will be present.
Also to import the tga files that you probably downloaded
from ribbit films or any footage in image sequence….you click
on import media and highlight the first image in the list and
at the bottom you tick “open still image sequence” and then
press open….thats it.
The rain clip you have isn’t embedded with an alph channel…
you have to key out the black with the chroma key video filter
or toggle with the “composting mode” on the timeline the rain
clip is on.
