<p>With luma keying, you provide a greyscale image to represent degrees of transparency (properly called an alpha channel) in addition to your background and foreground images. I have not used it in Vegas Pro, but here is a link to a tutorial:  <div class="youtube-embed"><div>

<p>In Sony Vegas Pro 13, I've masked the part where I want the text's black background to appear. It looks like this:</p>

<p><a href="https://i.sstatic.net/gW5gD.png" rel="nofollow noreferrer"><img src="https://i.sstatic.net/gW5gD.png" alt="enter image description here"></a></p>

<p>Now, I want to fade one part of the background like in below picture, where right side of the text background is faded.</p>
