  • Render Issue: Any Motion Is Rendered With Lines

    Posted by Sean Perry on December 14, 2011 at 2:44 pm

    Hey all,

    I’ve never had this issue in CS4, but while upgrading to CS5, it’s present. Not really a big deal because the final rendered product appears fine, but the issue becomes incredibly annoying when fine-cutting certain shots.

    Any fast motion is, in the preview menu, rendered improperly, or rendered with many thin lines rather than smooth pixels. I’m sure it’s as simple as pressing one button.

    Can anyone help?

    Thanks!

    Any chance you’re dealing with interlaced footage and haven’t got the settings quite right on interpreting it?

    The footage only appears with this error when previewed in After Effects. In any other preview (Quicktime, Final Cut, final rendered footage) it appears normal. So I don’t think so?

    most software will de-interlace footage for previews… ae does too, but sometimes it get it wrong.

    we can probably figure out if the footage is interlaced if we know more about it: is the footage sd or hd, and what’s the frame size and frame rate, and if you know where the footage came from that can help too.

    I shoot with the AG-DVX100B, meaning that the footage is SD, shot at 24 fps, and a frame size of 720 x 480. After Effects has never done this before (at least in CS4).

    However, I have always up-converted to 1280 x 720 and AE always renders a beautiful image.

    Shot 24P and as far as I know, I did not remove the pulldown.
