jagged edge from imported objects?

    I created an animated 3D text with transparent background using a trial
    version of ulead cool 3D. Then I imported this into premiere and put this
    over an existing video clip. Immediately I notice the edge is very jagged
    and have a thin black flickering border.

    Is this problem unique to this particular 3D software, or common when
    importing any objects with an alpha channel? What is the solution?

  2. You really didn't give much information outside the fact the video has
    an alpha channel. Considering the one thing you said about the
    flickering black border I can assume the title you created is not the
    same size as your video frame.

    You need to match the video frame resolution and frame rate.
    Animations often look better if you create them at 60fps when
    overlayed onto 30fps at 60 fields.

  3. My memory may be too fuzzy on this one, but I seem to recall that
    this program could do fine animated titles if the video clips of what
    they would appear over were first imported into Cool 3D...

    I use Cool 3D for import into Premiere all the time without the problems
    you've described. Check your export settings in Cool 3D, i.e. make sure
    they're 720 x 480, DV codec, 29.97 frames per second, etc.

    Sounds like aliasing.

    It is aliasing, but there is no reason for it the project settings are
    correct.
