Video 'shudders' when played on DVD

    I captured a short (2 minute) promo video for a friend at the highest
    settings I could. e.g. High quality DVD.

    Then, when I made a DVD video file at 8000 kbps (vbr) it looks great on the
    computer screen. However, when burned to a DVD disc and played on my player,
    the video seems to shudder... when I hit 'step' to pause the video I see two
    consecutive frames flickering back and forth.

    Mind you, when I repeatedly hit 'zoom' the shuddering stops at other levels
    of zoom, until it gets back to the original 1:1 when it shudders again.

    I've noticed that a video file I copied from a movie DVD is MPEG-2, Field
    B,Variable bit rate (Max. 9800 kbps). Should I be using Field B to burn my

    As you've discovered, the wrong field order is your problem. The difficulty
    arises in determining the correct field order as some software calls it (in
    your case) field A& B, sometimes field 1 & 2 and sometimes upper & lower
    field. Simply selecting the opposite of what you originally did should fix
    it. gives several excellent examples of this phenomenon.

    Thanks for your quick reply.

    I've also noticed that when I pause my captured MiniDV videos, I can see two
    consecutive frames at once, interlaced into one frame. Can you help me to
    capture my MiniDV tapes without this problem.

    I have the same problem whether I use WinDV or Ulead VideoStudio7SE.

    You're quite welcome Rus.
    Are you watching this footage ("pause my captured MiniDV videos") from the
    camcorder or after it's captured into the computer? Either way, what I
    suspect you're seeing is the difference in fields (2 fields = 1 frame).
    This is especially prevalent in scenes with motion in them (probably most
    videos you shoot, right?). If you go through the site I referenced, you'll
    see a number of pictures demonstrating exactly this issue. There's not a
    lot you can do about it either as it's generally a limitation of the
    videotape medium. Once it's burned to a DVD, you usually have the option to
    pause (freeze) on a frame or a field. At least my 4-year old Pioneer does.
