Beginner questions (reducing glare)

    Appreciate any help with this as I've never done it before:

    I have 22 hours of captured mini-DV (2 cameras) which I wish to edit
    down to about 10 hours of material.

    The main camera unfortunately picked up a lot of glare from several
    lights which seems to darken the overall picture:

    'scuse the back of my head. ;)

    Is there a relatively easy way to improve this, considering it will be
    on 9+ hours of the final material?


    The other main question is...

    I have a lot of data (300MB) and not so much hard disk space (400MB). I
    also don't have my own camera so I don't want to have to go back to
    original footage. How is this normally approached?

    Thanks for any help you can offer.

    A: buy a firewire hard drive, they are really inexpensive for te capacity you
    get.

    B: as to compensating for the poor exposure, it depends on your editing system,
    or if you can feed the footage through a proc-amp before you import it... You
    can make some adjustments in most NLE's to overall brightness and bring up the
    black levels a little if they are "crushed", but of course the best thing to do
    is shoot it right the first time. Auto-focus and auto-iris are best used to get
    you "in the ballpark", then turn them off and use the superior auto-adjuster
    betwween the ears.;-)

    Nope, there sure isn't. Truthfully speakinig if you hit the rails and
    exposed fully with the glare those shots are probably comepletely lost. You
    can do color correction in any NLE but DV is like any other digital medium,
    once you have flatlined it at the end of its dynamic range there is no more
    data to be had. You'll have to live with it.




    I suppose you mean 300Gig.

    Keep a batch capture list so that if you need to you can recapture from a
    rented camera or deck. Otherwise it is a matter of laying that footage off
    to another tape or another drive. Or a ton of DVDs.

  4. Is your camera completely static on a tripod? If you want to be fancy
    you could probably create a mask that includes just the lights, or
    perhaps including the walls around the lights, feather the edge and then
    do some brightness/contrast adjustment on only those parts of the image.
    The only satisfying thing to do is to buy more hard disk space.

  5. "relatively easy"? no. In the future, you won't include lights
    within the frame, right?
    Additional HD space. It is remarkably cheap these days.
    It is hard to even find a drive these days that is less than
    5-10x that amount of space. $70 will buy 80GB at my
    neighborhood vendor.

    First, a big thank you to all those who responded.

    I was thinking that increasing brightness more at the dark end than the
    bright end of the scale would be helpful.

    Based on my experimentation, I'd say that the film could stand to be
    brightened 7-15% depending on the shot, although I need to calibrate my
    monitor to be sure.

    I'm guessing I have to do this by hand and get it right before doing
    anything else.

    Does any software make this easier than Premiere Pro?
    Yep ;)
    Cool.

    Dave.
