  • Field dominance combining HD and SD footage.

    Posted by Bob Karsner on March 7, 2013 at 5:27 pm

    I am working on a project that was shot Green screen 1080i. I am needing the final product to be SD 4×3. I have created the green screen key in After Effects in an HD timeline then dropping that into a SD timeline, resizing the HD comp, and rendering that to a 4×3 SD ProRes 422(HQ) file.

    I’ve tried swapping the field dominance back and forth to hopefully adjust for the difference but my final video when played back through Media 100 is getting horizontal “tears” all the way across the screen in two or three different places.

    When played back through Quicktime on a progressive monitor, I am not seeing this effect… only through the Media100 playback to a TV monitor.

    What am I missing?

    Thanks
    Bob

    Which kind of hardware do you use? And is your SD 4:3 timeline interlaced or progressive? Is your master supposed to be interlaced or progressive?

    Your source clips are interlaced?

    And what codec do you render to in AE? ProRes, as you said? If you want to have interlaced ProRes in SD, then it is supposed to be Lower field first for NTSC, Upper Field First for PAL…
