50 / 60i Flourescent light flicker?

    I shot some material in Europe with a 60i HDV camera. I'm aware that
    European and North American flourescent lights pulse at different
    frequencies, which makes it difficult to shoot normal-looking video
    unless you've got the right kind of cam.

    So I've got a few night shots that have this ugly flicker on them, a
    bit like what you get when you point your camera at a television set.

    I'm not expecting any miracles here, but is there any way to clean
    this up in post? Some frame rate change, or maybe a plug-in?

    I'm using Vegas, also have After Effects, and can get access to other

    Unfortunately it is a bit late now. If there is a way to mitigate it in post
    I don't know about it. This can be eliminated during shooting by using a
    shutter speed of 1/100 second.

  3. There is an anti-flicker plugin for Virtualdub, which might do the trick
    for you

    You could try layering two copies of the video with a 1 frame offset
    and varying the opacity of the top layer until it looks right (it may
    not, I don't have any source material to try it on, this is just a
    stab in the light). This may yield an exposure that seems to be
    constant, reducing the flicker.

    I will try this.

    Do you mean having the top layer start just 1 frame before the lower
    layer does on the timeline?

    Thanks, I will look into this.

    I've gotten very good results with the MSI and Donald Graft deflicker
    plug-ins for VirtualDub. It depends on how pervasive the flicker is, but
    I've been able to eliminate quite a bit with a little judicious fiddling
    with the plug-in.
