user16354: My camera recorded flickering (black flashing) video, maybe due to low-lightened room.  I cant purchase the de-flicker plugins to fix the that video.
is there any free solution to fix that, with plugins or filters?
(p.s. I use Sony Vegas )

user16354: Wow, I have found interesting solution:
Method 1 (bad approach):

duplicate main video streams and put over the main stream, just off-seting them 1 frame after

change the opacity of the top video to 31%, second to 51%, (leave third at 100%)



and the flickering will be gone out. However, it has a downside - the motions will be seen a bit stretched (because of 3-frame repeated).
Method 2 (Better):
No need to reinvent wheel, there are priced plugins for it. I can't remember but there was a good plugin in market, named "de-flicker" or "anti-flicker" with free trial to test, which did excellent job!
