    wanted to re-encode this video after removing blends and/or ghosting, but havent had any luck improving those issues. Tried the usual methods (deinterlace, srestore, ivtc, decimate). If it's double-blended, how to fix? Apparently the video was an amateur transfer of film to video- I assume vhs tape- which eventually got onto dvd.

    There's a lot more going on here than just field blending and film pulldown issues. Much of the ghosting/tracer effect may be due to the video being run through a TBC with high digital noise reduction being applied. There is also something in the movement that makes me wonder if there was also some sort of standards conversion (NTSC to PAL or vice versa) applied in the mix. This one is a garbage in / garbage out situation. I'm sure someone can offer an avisynth script to clean it up a bit, but don't expect miracles.

    EDIT: Also, could this have been captured to your computer with the wrong field order? (There's something about the motion that makes me suspect it.) That would complicate things even more.

    I did a "quick stream fix" with VideoRedo, then extracted the clip with dgindex (honor pulldown flags)

  4. Yeah, as filmboss says, it's a mess. Heavy use of DNR combined with field-blending or double-blended some other way (field-blending a video source, maybe?). And it's field-blended from an NTSC source:

    Yadif(Mode=1)#or QTGMC
    Srestore(frate=23.976)


    Other than that, I have no idea how to fix this kind of thing.

    Using Srestore(23.976) looks slightly better than IVTC, but since I wanted to re-encode to dvd (adding pulldown), will I essentially be back where I started?

  6. With severely blended video like this use QTMGC and treat it as 60p.

    so just QTMGC which would give 59.94 fps? Or with srestore(frate=60)?

    To echo filmboss80's suspicions. This looks sped up. Is it captured from a US broadcast?

    Reducing to 23.976 fps looks slightly better than 29.97, but that was for a test-xvid (not dvd video).

    No, I just use QTMGC() and filter/encode at 60 fps. If you need DVD compatible output reinteralace at the end of the script.

    do you mean adding something like this at the end of the script, with encoder set to "interlace"?
    SelectEvery(4, 0, 3)
    Weave()

  12. Reinterlace 60p to 30i:
    Code:
    AssumeTFF() # or BFF, whichever you want
    SeparateFields()
    SelectEvery(4,0,3)
    Weave()

    aside from any clean-up, is this going to look much different than the original?

    No. The point is it's too far gone. You can't eliminate the blending so just live with it. Clean up whatever else you can.

    I only wanted to fix the blends, not "polish a turd."
    Thanks anyways.
