Slowmo video Windows builds available!

37

SlowmoVideo is a slow motion video editor that allows for slowing down footage by large factors, calculating intermediate frames using optical flow. Initially only available for Linux, there's now also a Windows version available.

Some of you probably remember that little program Slowmo video that was posted here on BlenderNation a while ago. Well, for those of you windows users like myself who wished you could try it out but couldn't, your hour of glory has come! As of August 13, 2012 there is a windows binary available on the site for you to try out!

    thats awesome

  • wis98

    Just what i needed! Now testing if it does a better job than after effects ;-)

  • b.compositor

    Pure awesomeness! Would definitely love to see this ported to the VSE!

    • http://www.hypnosis.lv Karlis Stigis

      Definetly

  • daredemo

    tried to run it on Mac OS X with Wine, but menus etc do not display text, thus making it impossible to use.
    can anyone else try? Do you know a fix?

    • defkon

      I would try using VirtualBox to run the Windows version on the Mac. I run lots of Windows-only apps on my Mac this way.

      • daredemo

        if I wanted to use VirtualBox and install a full other op system, then in this case linux would make more sense, as this is, firstly, linux app. However, I do not want to use VirtualBox for this.

    • Chaos

      What about using Wine on a Mac to run the windows version?

      • numanair

        Isn't that what he tried and what didn't work?

    I want to donate this dude some serious € !
    I've been using Twixtor since way back, but the pure quality of Slowmo, beats Twixtor by too much to be describe!

    • http://www.hypnosis.lv Karlis Stigis

      Well, I can't say it beats twixtor, but this definetely would be awesome to have in blenders video editor..

  • Ignatz

    The software looks very impressive. Unfortunately, the install on Windows is not straight forward. The program seems to require certain extra components and I have no idea where to find them nor where to install them.
    But aside from all that... yeah, impressive!

    • Nathan

      It's actually pretty straightforward - you just need ffmpeg.
      You can download it here: Just choose the latest one in the "32-bit Builds Static" section,
      http://ffmpeg.zeranoe.com/builds/

      Slight complication - it's zipped using 7z compression. You can use the free 7-zip app:
      http://www.7-zip.org/

      Using 7zip unpack the ffmpeg file to a temporary location.
      The file you need is ffmpeg.exe in the bin directory.

      Copy this to the directory you want to install slowmo too (can be anywhere).
      Download the slowmovideo executable:
      http://slowmovideo.granjow.net/builds.php#h3_Windowsexecutables

      And put it in the same directory and it should work.

      Just testing it now - does seem very good.

  • tichy

    how does it work? I Mean... HOW? I am amazed! really amazed! I throw my self out of the next open window.
    It is like, the software is generating the missing images... BUT HOW?

    love it, btw!

    • luca

      It calculates the motion of pixels and interpolates.

    O.O This is awesome!!

  • dave62

    AWESOME!! AWESOME!! AWESOME!!
    Already used it on linux. Was hard for me to install but then works great!
    Cant wait to try on win..

  • terrachild

    I've been waiting a long time for this. I posted on their site about needing a Windows build, and they made it sound like it might never happen. The drought is over!

  • dave62

    @nathan
    I cant get it work on win7 with cuda activated like on linux. Where can i find the flowbuilder binaries which i need to setup in the prefs? Any

    • Nathan

      From the write-up it sounds like the CUDA libraries he's using don't exist on windows which is why he originally couldn't port it. Now he's got a CPU flow library (not sure if the underlying algorithm is the same) hence the windows version.

      Anyway, I haven't got an nvidia card so I'm just using it in CPU mode which seems fine.

      • dave62

        Hey nathan,
        i wrote to the coder because of the missing cuda acceleration. Yes, due to some compiler related problems under windows the cuda part is not yet done, but hopefully will in future as i understood.
        ..Cant wait for fullspeed:)

        thx

  • JnZ

    Here is a quick test

    Background flip is my fault...

  • JnZ
  • Dynavision|FX

    Wow. Any chance of this source code finding it's way into Blender? I'd love to stretch a video track, add the "Slowmo" effect and it fills in frames. Or connected to a speed ramp curve for that matter. Nice work, though.

  • onjoFilms

    But everybody who is anybody owns a Mac now :)

  • blazer003

    There don't appear to be forums for it, so I'll post a question here. You press H to bring up the help menu with various shortcut commands. I used one of them to get into move mode, but now cannot get back into a mode where I can create new nodes. I see no key combo listed for how to get out of move mode and back into node creator mode. Any suggestions? I'm guessing it's T-> then something, but it's not listed. I've tried doing a lot of the Blender type shortcuts (Ctrl+LMB, Ctrl+RMB, Shift+LMB etc.)

  • David Haymond

    Awesome! I've been waiting for this ever since I found out about SlowmoVideo. Great news!

  • http://www.hypnosis.lv Karlis Stigis

    Can this be implemented in Blender's video editor ? This would be awesome.. like time remaping with frame blending in after effects..

  • krisang

    but I am not able to import the video file... any idea??

    • blazer003

      What error are you getting?

  • http://www.facebook.com/profile.php?id=100004211582257 Troy Robinson

    Is there something missing from the windows version? I saw that the GPU
    is not there, but what is flowbuilder? In the preferences there is an
    option to set a path to the binary, but there does not appear to be
    anything.

    Also I see errors pop up in the console that refer to this (although it seems to be working in the quick tests I have done)

    • dave62

      the coder of slowmo told me that cuda acceleration is not available under windows yet. Atm only under linux.

      • http://www.facebook.com/profile.php?id=100004211582257 Troy Robinson

        What about the Flowbuilder? is there something missing there?

  • Gustav Hartvigsson

    Too bad it was written in C++ and Qt though...
    Some unnecessary dependency imho...

    So... I can only see this fail from now on.

  • ichabodcole

    Was able to get a Mac build together (have not tested on anything but Mountain Lion). Feel free to download https://docs.google.com/open?id=0B9KPvyUpCYPycUZUOXpGRUU5VW8 (click the file that is called slowmoUI)

    • ichabodcole

      And can I just say, "Holy crap the comments are using the hardest captcha EVER. I had to go through 10 before I could read both words." There I said it.

  • EmPeeKay

    Quick test I threw together.
