Hello Biomech-L subscribers

We ran a series of tests where we used high speed videos at 500 fps. The
ambient light could not be turned off, therefore our videos show a huge
variation in brightness from frame to frame. The ambient lights flicker
at 120 Hz.
I tried various filters available for virtualdub (such as deflick and
msu_deflick) to remove the flicker, but could not see any significant
improvement.

This is not a new issue, but I could not find any posts in the Biomech-l
archive regarding methods/tools to remove flicker from digital videos,
after they were taken. If you have any suggestion or experience, I'll be
grateful if you could share them,

Thanks,

Damien
