    This really sounds like interlacing.

    Are you previewing on an NTSC monitor or your computer monitor? If your computer monitor, and you used the DV NTSC preset, that means you are looking at interlaced footage on a progressive screen – so you will see “black lines” in things that move – these are “scanlines” and will not be visible on an interlaced monitor. They are even MORE visible on computer screens with hi-contrast (white on black).

    If you will be outputting to an interlaced format (NTSC DV or DVD) then try to preview on an NTSC monitor and see if there’s still an issue. If you are NOT outputting to an interlaced format, I’d suggest working in a progressive comp (Ie NOT using DV preset unless you NEED it).

    Any chance you could post a movie, so we can see exactly what it is you are seeing?

    If you’re encoding for DVD make sure that you are using an acceptable method of encoding and an acceptable bitrate. If you can encode 2-pass (or more) that would be preferable, and try a target bitrate of around 6Mbps, don’t peak at more than 7.5Mbps.

    Another issue you may be facing may be due to interlacing. Make sure you are not using any thin (1 pixel or less) lines as these can flicker in and out as they pass through different fields.

    One last question… What are you viewing the final output with? If you’re viewing a burned DVD in your computer at full screen then that’s definitely the problem. If you’re viewing on an LCD screen at all that can contribute as well.

    How are you viewing your final output?

    I am doing both. I am viewing on my computer Monitor, A NTSC monitor by way of a AJA zena card, and then burning to a DVD via ENCORE with high transcoding settings. Why would that be the problem?
