Activity Forums Adobe After Effects AE to FCP Funkiness

    I’m currently working on a small demo video for a web tool. I worked up some quick animated highlights and other elements for the buttons, etc. in After Effects.

    I rendered them out and brought them into FCP in order to time them out a little bit better with the voice over and every time I lay them over my existing footage everything seems to dim a little bit. It’s almost as if, instead of an alpha channel, I’ve got a really low opacity instead. The animations and other elements that I rendered out look fine, but any footage below those layers are affected.

    I’ve never had this happened before and wondering if anybody had any bits of advice.

    Thanks again for all the hard work everyone throws in!

    I have had this problem before as well, so I am no help to you, but am also curious but never sought out the answer. Are you overlaying text onto video? My problem was I was creating lower 3rd’s for titles, and when I was bringing in the text I had it gaussian blur and fade in, while it was fading up it was like it was fading up from a black bg, instead of an opaque bg, like it should have been since it was an alpha channel, it must have something to do with the way we are outputting our alphas, sorry I can’t be of help, but it would be interesting to know what the problem is, for a short term solution I brought the text and lower 3rd bug in as seperate QT’s and did my opacity and blur settings through Final Cut, which isn’t the best result but worked for what I was going for.

    Hello
    I had the same problem, so I fixed it by taking a blank frame from the AE export and making the entire duration of the piece… lucky it was only a few minutes… and placing that stretched frame across the length of the time line and RENDERING… It fixed the flashing… but anytime I changed anything on the layers below I had to re-render. So i just turned off the top “fix” layer until I was totally done. I presume you could just export a blank document with a similar length of the final FCP file out of AE with the same Alpha info and that would work too, but then when would you get time to check COW. Isn’t that what rendering is for?

    Hope this helps.
