  1. It seems that this video is heavly blended. Is there any filter that can deblend this video?

  2. Exblend(PAL=1)
    TDecimate(Cycle=6,CycleR=1)


    Seems to do a decent job with the sample.

    Replying so I can find this again.

    I would have used srestore(). Why use this instead?

  5. SRestore() can't restore a frame that only appears as part of two blended frames. It can only remove blended frames (and duplicate frames). For example with original film frames A, B, and C, the video has:

    A, (A+B,)/2, (B+C)/2, C

    Frame B never appears as a clear frame. You need a filter that subtracts A from A+B and/or C from B+C. SRestore() can't do that.

    <edit>
    All this time and I didn't realize SRestore actually has some ability to deblend. It just doesn't work well with this video.

    Did you have a look at the sample? Did you try SRestore? I did both and it didn't work out so well. It's all progressive and within each six-frame cycle are two blended frames.

    SRestore(omode="pp3")
    TDecimate(Cycle=6,CycleR=1)


    It creates artifacts and the decimation gets screwed up.

    No. I was only looking at the scripting.
    I've never used exblend() before.

    Hehe, me neither. But I knew about it and when SRestore didn't work well on this sample, I finally decided to try and figure out how Exblend worked. As it turned out, it worked very well indeed. And xuguang_he reported back that it worked just as well for his entire movie. So, it's definitely worth keeping in mind for the times when SRestore doesn't work, or doesn't work well, or even to just use it in place of SRestore with certain kinds of sources.

    Thanks for the explanation.

    I have one particular ugly video that I want to test this on. What I'd done before was to stack several srestore(), which did somewhat work. TFM() was good on another one.
