GL2 help

  1. Hi -

    I have a bit of a dilemma that ended up in multiple questions...
    perhaps someone can help me out please?

    alright well i own a GL2. i am aware of the fact that shooting in the
    30p frame mode is not true 30p and in fact cuts off some available
    resolution. so what i've been doing instead is shooting in normal
    mode, but on a shutter speed of 1/30, so it still looks fairly filmish
    and is sort of progressive since 1/30 would mean the 2 interlaced
    frames would be showing the same image. but anyway, here is my main
    problem.

    i now need to film outdoors, and i just realized a couple days ago at
    the GL2 is TERRIBLE in bright sun. even with the ND filter on, it is
    still really overexposed, unless you close the iris and raise the
    shutter speed. and well, if you close the iris, you lose control of
    the focus. and if you raise the shutter speed, it no longer looks
    progressive or anything close to film at all. i WANT to somehow shoot
    in a way that still looks filmish. i figured buying some ND filters
    would work, but the iris almost fully open and the 1/30 frame rate is
    still too much for any of the filters i have, even when combined. so i
    now ask this question. is there a way around this while still using
    the 1/30 frame rate and not having to nearly close the iris? i found
    out, though, that if i turn frame mode on and raise the shutter speed
    to say, 1/60, then its fine. but then, what happens? am i losing
    resolution in frame mode? and also, how can the shutter speed be 1/60
    if im shooting in 30p? i can also raise the shutter speed to 1/720,
    and still be in 30p. how is this possible if im shooting at such a
    high shutter speed? should i just leave it at 60 and use frame mode or
    is there some filter combination i can use to avoid this?

    any help will be GREATLY appreciated, really guys, thanks a lot

  2. Shooting at 1/30th and below *will* reduce resolution and
    increase stair-stepping effects (at least in Sony cameras...) since
    one field is dropped. The image is unacceptable except for
    emergency use in very low light, to reduce gain effects. If you
    must throw away the advantages of interlacing in video for
    standard interlaced TVs (a mystery to me why anyone would
    want to, except for video displayed ONLY on computer
    monitors...), then the 30p mode would be the way to go.
    "30p" refers only to the display mode, not the shutter speed,
    BTW...
