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 )

  • I ran into the same issue, but with flickering of a set of monitors with a refresh rate not lining up well with my camera. The current answer offered no remedy, nor did I find any useful fx for this. What did help to some degree, was to render the 50fps source to a 29.97fps mp4, should it be of any help to anyone.

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%)

enter image description here

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!
