slow motion problem in Vegas

    Is it possible to do slow motion in Vegas without getting that double image
    from the two fields? When I see slow motion on TV, it is made of a single
    image, but when I do it in Vegas, I get double images in fast moving scenes.
    How do I avoid that?

  2. Right-click on the clip and make sure Sitches->Reduce Interlace Flicker is
    checked. That should do it, I guess.

    There is no "not professional" editing software able to do a real slow
    motion without flickering or double images or "strobo" motion.
    There is however a freeware that does it! But you have to handle the clip
    where you want to apply slow motion independently and re-import the clip in
    The program is called "Motion Perfect" and can be downloaded from the
    Dynapel site.

    Cool. Thanks very much.

    Something else that helps is to set project properties field order to
    "progressive". Render to new track then reset field order to "lower field

    There's a free trial version but it looks like you have
    to pay for the software after a trial period. That's
    not the same as freeware.

    I will try that.. Isn't that the same as choosing "progressive" when
    selectively rendering? I tried that and it didn't do anything. From
    reading your posts on here, I know that you know Vegas pretty much inside
    out, so I will try your suggestion. I'm a big, big fan of this program as

    You're right, but the limitation of the free trial version is, if I remember
    well, a clip duration of 30 sec, and you will probably never apply slow
    motion for such a long time. Things are different for another feature of
    Perfect Motion, which is rebuilding of dropped frames. But even in this
    case, you can split your clips in parts smaller than 30 sec.
    As far as I am concerned, I never used Perfect Motion for clips longer than
    30 sec, but I purchased the software however just because I fiend that it
    earns rewarding.
    It works well, it' s efficient, it' easy to use and the interface is
    outstanding and intuïtive.

    When you apply slow motion to a clip, for ex. 50% of speed, it means that
    you are missing 1 image out of 2. Normal video editors rebuild this image by
    copying the following or preceding image, or averaging both appending
    images. Professional tools (like Motion Perfect) or editors CALCULATE the
    missing image by comparing the preceding and following image. They keep the
    fixed parts of the image and calculate NEW intermediate positions for the
    moving parts. That's why there is also a lot of rendering needed for real
    slow motion.

    Saying anyone knows Vegas inside and out is a HUGH statement. Thank you, but
    NO. Very deep, very organic software, as you know Sanman (and many others).
    Yes, you'll get progressive with your selective renders. Once again, many
    ways to do the same thing....... gotta love this software. Progressive has
    helped on ski clips I slomo'd in the past. That's where the deiterlace setting
    comes into play. Maybe I was buzzed, I'm playing with some new harsh footage
    that should tell the truth.
    Just did the Dynapel Slowmotion download and not getting good results
    here. Maybe a setting I've missed?
    Loaded a DV avi in and out (Cars at 35mph with and without high speed
    shutter= harsh test) at maximum speed render setting and slomo factor 2.5 (
    third speed). Ended up with errors on static subjects around the cars> (ghost
    around car that made pavement/trees ripple as it went by).
    Rendered out the original DV file to uncompressed, then in and out of
    Slowmotion at best quality rendering/keyframed every 8 frames/quality at 100%
    and got the same bad results.
    It touts interpolating & morphing to do it's
    thing. Vegas does the interpolating part and looks better here. Anyone have
    any ideas about the errors I'm getting with SM output?

    I'm using Motion Perfect since mmany months with really perfect results. I
    however do not use the wizzard, but advanced settings. I select best
    quality. Important is also the encoder you use. Try diefferent ones to get
    best results (I selected Matrox).

    I downloaded the DynalPel software too and tried it on a clip of an F1 car.
    It made of big mess of that with very bad artifacts and shadows. The
    resultant footage was unusable. I gave up on it.

    I did exactly the same for motor bike racing and got outstanding results.
    You should try some manual settings (don't use the wizzard !) and of course
    read the help files, where you will find some useful tips.....and
    limitations !.
