    Hello Everybody,

    Here is my problem. I have HDTV, and whenever i capture video, there is a constant luminance type of flickering throughout the video, from all channels. I get this using different OSs and video capture utilities, and even played around with my HDTV to remove it, and havent been successful.

    So i am now attempting to filter out the flicker. But havent been so sucessful using Donald Graft's FLicker filter or temporal smothers ect.

    Here is an example of the liminance/flicker i am referring to.

    This is the normal video picture

    This is the frame that flickers

    The flicker lasts for 1 frame, and happens every 2-3 seconds


    Any help on filtering this out would be greatly appreciated.

    Did you capture this from an analog source? It looks like macrovision (copy-protection).

    Its from a Digital Set Top Box. The Channel Guide states that the program is Digital. I suspected that it could be macrovision that is causing the flickering.

    Any idea how to filter it out?

    I use a video image stabalizer. Used it in the VHS to VHS days, and tried it out for somebody else on this forum. (mine worked great DVD to DVD recorder; he couldn't get his to work.)

    If you're capturing via analog line, then it's quite possibly macrovision. I have an inexpensive unit (AUS$70). A good thing to have anyway, for other forms of analog video noise as well.
