Cannot remove solid black background in text generator

I cannot create text with transparent background it's always coming out black. I can change text colour but not background. I have reinstalled Vegas 13 Pro having deleted all leftover files as you suggest but it is still creating text with a black background.

Thanks in advance Derek

Hi

First make sure you have reset the program - this will make sure you have not turned on a setting by accident.
Follow these instructions here:

Make sure your Text is always placed on a video track above all other tracks.

Make sure to start with this option at Step 1.
When you get to step 3, open Advanced.
Step 4 shows the controls for background colour/transparency.
Click on top of checker-board.


Make sure this is dragged to ZERO - this is now set to 100% transparency.

And if you want to change the background colour, see what happens when you choose something other than zero (last pic above) and use the colour picker, type colour values, or use the eyedropper to sample a colour from your screen. Try also muting your video event on the track below (right-click on it, Switches, Mute) to see what you'd get.

The issue is likely because the text media is using a solid background. In the Generated Media window, set the background color's Alpha (A) value to 0 to make it fully transparent. Also, make sure the text track is above any background and the compositing mode is set to "Source Alpha." I once had a similar issue while using a tool called Brat generator for overlay text, and it turned out to be a background alpha setting too. If you're seeing black after rendering, use a format that supports transparency, like QuickTime (MOV) with RGB + Alpha and a codec like PNG or Uncompressed. The preview may also look black if there's nothing behind the text, so add a background to confirm transparency is working.
