  • Field Dominance Question

    Posted by Tom Alexander on February 5, 2010 at 10:27 pm

    HDV 10801 project had scan line problems with “freeze frames” taken from HDV material on QT output. An earlier post suggest changing field dominance to “none.” That corrected the still problem but caused the HDV material to degrade on any moving shots. In addition, FCP made my freeze frame shots 1920x 1080 as opposed to the sequence settings, as well as, very large in size. A few are 1gb in size.

    Settings:

    sequence HDV 1080i 1440×1080 16:9
    QT set at apple pro res HQ.
    Output to Quicktime is HDV 1080i

    Any help would be appreciated!

    Leave the field setting to upper for the sequence. Only set sequence to none if the content is true progressive. HDV is interlaced so that was poor advice.

    All you have to do is drop the deinterlace plugin on the freeze frames. FCP has a basic deinterlace filter which is fine for a freeze frame. I use Nattress deinterlace filters if I choose to deinterlace moving pics in an interlaced sequence to achieve a progressive look. Good deinterlace plugins help reduce the resolution loss.

    So Tom, I’m just curious if you read my or Will’s post at all in your previous thread. We gave you the same advice you’re getting here.

    1920×1080 is the correct size.
    Use the deintsrlace filter.
    It won’t be a gig I’d you export as still image and choose tif,
    jpeg, etc.

    Did everything recommended. Still having the problem on about 10 still “freeze frame” images.
    Woke up to a new QT output with the same problems. Scan line double images on 10 stills and
    HDV 10801i material that was once pristine has an annoying scan line effect on camera moves.

    I agree with a recently added post. FCP seems to have no intelligence. If everything I put into this program was set right to begin with, just making “freeze frames” from within the program from the source material, should not be so impossible. And to make things worse, everything looks great
    in the program viewer, it’s on Qt output where the problems show up.

    I’ve done programs like this several times before without a problem.
