Thank you for you answer, I really appreciate it. However, I can't get it to work anyway. Even though I make it a Compositing Child, it still creates the fade for the individual clips in the tracks. Doesn't matter if I select track 1, track 2, or the side of track 1 which then selects the parent and all the childs. I guess the whole idea with creating parent/child is that it can be treated as "one clip", which would solve my problem. But I can't created the fade for the united tracks.

What I want is the effect to be the same as if I did a workaround and created new projects for each clip with overlay and rendered it. Of course, I don't want to create projects just to merge the overlay into a clip and then import the re-encoded file into my "real" project file.

Yeah, that kind of sub clip thing can be done in most professional editors but I was surprised that Vegas limits you to a single timeline.  I'll try giving the compositing thing a try and see if I can get it to work later, but I've been in prep mode for a conference this weekend so time has been limited.

<p>I was having this same problem and finally figured out a solution.</p>
<p>My project consists of one main video track with several tracks of generated media above it (to obscure aspects of the video track that I don't want to see with colored boxes).</p>
<p>Then above all of that I have a secondary video track to which I occasionally want to fade in and out of from the main video track.</p>
<p>The problem is that when I set the fades, the generated media fades out too and what it's obscuring is briefly visible during the transition.  Or if I don't use a fade on the generated media, the bars are visible and then abruptly disappear during the transition.</p>
<p>The solution was to add a new video track with a generated media object black background beneath the secondary video track.  Then whenever I fade in to or out of the secondary video, I also add the same fade to the black object, and the primary video and all of its generated media fade in/out evenly with each other (i.e., the obscured content is not visible during the transition).</p>
<p>Thanks,

<p>The way I do this is by creating a solid colour (black) clip, placing it above the two clips and fading it in. Remove the fades from the other two clips when you do this. </p>

<p>The original problem I had was to put an overlay (static image) on a video track. All guides/tutorials I found does this by putting the image into a separate video track. I would prefer attaching the image to the actually video clip instead, but fair enough, it works.</p>

<p>However, when I try to fade out the video + overlay, they do this at different "pace". The video is recorded from gameplay, and I want to cover the chatbox with a black image. It works fine, and I can't see through the image at all. But when I fade out the video track and the image, I can pause in the fading and actually see the chat box. This is extremely frustrating, and not at all what I want of course.</p>

<p>I have tried different things, fading out by dragging the right corner, and a composite level envelope, but it doesn't help. It doesn't matter if it transitions into another video clip or to black, same problem occurs anyway.</p>

<p>Here is an example of how it looks:

I was having this same problem and finally figured out a solution.

My project consists of one main video track with several tracks of generated media above it (to obscure aspects of the video track that I don't want to see with colored boxes).

Then above all of that I have a secondary video track to which I occasionally want to fade in and out of from the main video track.

The problem is that when I set the fades, the generated media fades out too and what it's obscuring is briefly visible during the transition. Or if I don't use a fade on the generated media, the bars are visible and then abruptly disappear during the transition.

The solution was to add a new video track with a generated media object black background beneath the secondary video track. Then whenever I fade in to or out of the secondary video, I also add the same fade to the black object, and the primary video and all of its generated media fade in/out evenly with each other (i.e., the obscured content is not visible during the transition).
