  • Strange Compositing

    Posted by Dan Lachevre on July 26, 2006 at 10:40 am

    Have a weird problem with compositing modes. I’m using the ‘Screen’ compositing mode on V2 with another video layer underneath on V1. I have dissolves set in and out on the V2 layer which works fine until it is rendered. Once rendered the fades are ignored and it just cuts on.

    Any ideas? It’s strange it fades in & out fine until rendered.

    Cheers

    You will need to precompose the V2 layer.

    This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”

    Hi
    Typing precompose into FCP’s online Help results in 0 occurrences…
    Typing “define precompose” into google I get this:
    Quote:
    [i]You can precompose a layer or multiple layers in After Effects. Pre-composing is often the answer to vexing nesting problems. Say you wanted to animate a car going down the road and show the wheels turning. You could first rotate the wheels on the car, then pre-compose the car and the wheels. Then you can move the nested comp (the car with the spinning wheels) down the road.

    To pre-compose layers, select the layers you want to pre-compose, (Command – select to pick layers that are not right next to each other) then choose pre-compose under the layer menu.[/i]

    How does that work in FCP?

    Substitute the word “Nesting” – same deal.

    did you try using opacity keyframes instead of transitions? that worked for me once but i’m not certain which fcp version it was.
    “pre-compose” is the term in afterfx, “nesting” in fcp.

    You may have already done it, but often when this kind of thing happens to me, a trusty old preference trashing and quiting fcp does the trick…usually after a lot of head scratching.

    Best,
