What's a good slow-motion effect plugin?

    I recently had a chance to try out Twixtor. I took some DV footage,
    deinterlaced it with Hicon32 (which does a decent job, though it adds
    bleeding artifacts along the edges), and set Twixtor up to basically
    double the number of frames.

    Here's what I ended up with. Let's say we took frames #20 and #21. We
    need frame #20.5. So we set up a crossfade between the two frames and
    use the halfway point as our new frame #20.5. That's what Twixtor spat
    out. Crossfades. Not only that, but the new frames had quality
    abnormalities which, while unnoticable during playback, were bluntly
    identifiable when analyzed at a slower rate. I was deeply disappointed.

    So, Twixtor appears to be basically worthless for my needs. The
    playback of the above-detailed crossfade "slow motion" effect was about
    as pathetic as one might expect. I need a new recommendation.

    So, what's good? :) And while I'm at it, what's a really nice
    deinterlacer? As mentioned before, Hicon32 does a good job (albiet
    with a big X over the image), but it does introduce those artifacts on
    the edges, and they're not subtle. Would prefer a deinterlacer that
    serves as an AEX plugin, or something that can be used in Premiere Pro.

    I think you must be doing something wrong, because twixtor is freaking awesome.
    Anyway, try realviz re:timer, maybe it will work better for you.

    You never deinterlace before doing a slow-mo. Deinterlacing
    removes half of the motion information, and the last thing you
    want is les information. You actually want more. You can
    slow things down and use frame blending in AE, or you can
    use one of the other applications. I have Retimer but it is an
    old version. there is now a plug-in version, and I think they
    have added more automation.

    "Out of the box" the version I have goes beyond simple frame
    blending by attempting to analyze the motion in the frame and
    do morphs from frame to frame. You can do some pretty amazing
    stuff if you take the time to adjust the morphs by hand (a lot of time
    with the older version I own).

    It was very expensive when I bought it (~$5000), but it may
    have come down.

    Well, maybe I should have been a little more specific. I wasn't
    deinterlacing the DV into [email protected], but rather 60fps, which was
    the whole point. I also checked the results frame-by-frame and they
    were satisfactory. Ie, precisely what you get when you watch NTSC on
    any decent plasma display (or a DVD player with DCDi, for that matter.)
    There was not loss of motion information.

    The reason I went through the trouble of deinterlacing it was because
    I had originally passed the video through Twixtor in its original DV
    format. The result, in addition to exhibiting the cheap crossfade
    effect described earlier, was video that seemed to have sacrificed
    half of its vertical resolution here and there. Not acceptable.
    This sounds like something worth checking out. Thanks!
