Every 15th Frame dropped - Any way to smooth out in Vegas 4 or other tool?

    I'm working on a project with video footage from three cameras, none of which
    were under control (from a stage performance, some spotlight, and some
    stagelight)

    1 - A good quality MiniDV recording from a tripod. The trouble is that most
    of this is zoomed out much further than I'd like, and sometimes, the operator
    wasn't paying attention and the action was off-camera. This is the primary
    source I'm using.

    2 - A pretty-good quality MicroMV recording taken without a tripod. Much of
    this footage is too shaky to use, and much of it is zoomed in _too_ close to
    use. But some of it is really good.

    3 - A very noisy Hi-8 recording taken without a tripod. Some of it is too
    shaky, and all of it is very grainy. I've used a _little_ bit of this
    footage, but more or less only as a last resort, and generally not for the
    spotlit scenes, where the noise is worse.


    The problem is that I just realized (after basically finishing the project)
    that the MicroMV footage has every 15th frame dropped. Every 15th frame is
    contains every (15+1)th frame as a placeholder. This results in the picture
    visibly jumping every half-second. It's very distracting, and I was hoping
    for some way to smooth it out. Does anyone have any suggestions?

    I tried two things, based on an erroneous assumption. I figured the "jump"
    was caused mostly by the fields being repeated (going in the order of ...28,
    29, 32, 33, 32, 33, 34, 35...), and that a slight pause every 1/30 second
    wouldn't be as noticeable as the back-and-forth field effect.

    1 - I re-encoded part of the MicroMV footage as progressive scan, dropping
    every other field. This didn't help.

    2 - I took about 8 seconds of footage, exporting every duplicated frame,
    deinterlacing twice (once with odd field, once with even field), and
    re-importing the deinterlaced pics in order, in place of the duplicated
    frames. This helped minimally, but the pause every half-second was still
    very noticeable.


    Is there any way to smooth out this pause? I know darn well that a good deal
    of the quality is lost and cannot be retrieved (getting the original MicroMV
    tape, finding a MicroMV device to use, and re-exporting the footage isn't
    really an option, unfortunately, just in case the original footage on the
    tape doesn't have this flaw). But is there any way that I can smooth this
    out so that it's not as distracting? It seems that all I would need is a
    simple filter to create an interpolated frame between frame 14 and frame 16,
    but considering that my last two ideas didn't pan out, I may be off base on
    this, too, and an interpolated frame might not successfully smooth it out
    either.

    How about morphing? For the missing frame morph the two good frames to produce
    the missing frame. I'm sure it's a lot of work. Try what you can do with
    "WinMorph" (www.debugmode.com) which I believe is freeware. The program is very
    high quality and has been used in big-time Hollywood movies. The author, Satish
    Kumar, is in high regard in Vegas Video editing community and elsewhere. Drop him
    a note in debugmode.com forum.
