Two Track Video Fade
This one ought to be easy.
I do these industry test videos and most scenes have video insets over video, but when you fade them both out, during crossfade transition, the area of overlap get brighter. I know that if you have two layers stacked, when they are both transparent, they reinforce in areas of overlap.
When I edited with Velocity, I didn’t have enough realtime preview layers so I rendered the comp down a couple of time, flattening it. It was the flattened video I faded in and out of on the Velocity timeline, and layered elements faded out cleanly, together.
But enter a new killer editing system and Adobe Pro CS4. I don’t have near the experience with this toolset, but I’m learning fast and enjoying it.
Anyway, I’m getting video assets from the client digitally and not on DV tape. And now even 8 layers of stuff previews realtime, nearly perfect on the production monitor. So there is no more flattening (and I don’t want to add more steps anyhow, that’s the point of digital assets and computer horsepower).
Now the client complains about seeing wierd area of overlap during transitions. He’s talking about the reinforcing of semi-transparent layers mentioned above.
How can I fix that without flattening to an interm mix? Is there a way to just tell Premier that the layer on top needs to stay fully keyed, but just fade as if mixed with the layer below? Nesting? Add a differently named fade effect? Alter a fade effect paremeter?
Any tips? Thanks.

Keyframe “opacity” for both tracks at the same rate. (In your “effects” tab, usually with/behind the source monitor.)
It works, I’ve done it multiple times.

Thanks, but I did that and it looks the same as applying a dissolve (of the same duration) to the start of the clips. During the dissolve, you see the background through the inset.

In that case, what I’d do is render out the clip as uncompressed, bring it in and simply do one overall opacity change.

How about this – put the video you want to fade to on TOP of other layers, so instead of fading two layers out, you are fading one IN.
I’ve done that before in the situation you describe. If need be, use the Razor to cut a short piece of underlying clip and just move it straight up to top layer, add the fade, done.

Hey! That’s pretty smart. I got around to that solution with Combustion composites in the past, but it didn’t dawn on me this time. Thanks!
