    "Strobing" while using noise reduction filter

    I'm transferring a VHS tape to DVD and would like to use a cleaning filter with VirtualDub. But every one I've tried adds some "strobing" to the image. For example, there's a section where a number of people are waving hello and the motion of their arms is jerky, like a strobe light was on them.

    I've tried Temporal Smoother, Flaxen's VHS filter, Smart Smoother, and some others. They all seem to cause this problem.

    Can someone recommend a good filter to clean up VHS that will not cause a problem with fast motion, or settings for the above filters that will minimize it?

    Thanks for any help!

    that really shouldn't happen. is the source interlaced? using any other filters before/after?

      Figured it out with help from another forum - I was encoding bottom field first, when it should've been top field first.

      SO many variables - my god!
