    I want to get the 'frame doubling interpolation' using PotPlayer but I don't want to install SmoothVideo Project (SVP). Recently I discovered that Potplayer comes with AviSynth support but for some unknown reason I can't get it to work.

    The 'How to use AviSynth'' link points to a Korean guide here:

    Can someone post a guide in plain English so everyone can understand how can be done? Thank you.

  2. There's nothing special.. You need to install avisynth and the plugin to use in your system. You can get the both links in the screenshot above.

    ps. copy interframe plugin to "c:\Program Files (x86)\AviSynth 2.5\plugins\".

  3. I have Avisynth installed but not a MT (multi-threaded) version. Therefore the only script which worked for me was the colorbars one. You need a MT version for the rest so I couldn't check any of this.

    There's an SVP version of Avisynth which I assume is multi-threaded. I'd try it.

    Install Avisynth. Don't change the default installation location. That might be bad. Avisynth should install with a subfolder called plugins. For XP it's located:
    C:\Program Files\AviSynth 2.5\plugins
    There'll probably be a file or two inside. Just leave them.

    It looks like the scripts require two plugins. One of those is MVTools.
    That's the SVP version of MVTools, not the standard one, but I think it's the correct one. Unzip it and copy the dlls inside to the Avisynth plugins folder.

    The other plugin is InterFrame. You can download it from here.
    When you've unzipped the file, copy the unzipped folder to avisynth/plugins. There's another folder inside it, so you should end up with a folder structure like this:

    AviSynth 2.5\plugins\InterFrame-2.5.0\InterFrame2.avsi
    AviSynth 2.5\plugins\InterFrame-2.5.0\Dependencies\svpflow1.dll (there's three other dll files in the same folder).

    I think that's it. If the planets are lined up just the right way and it's not raining too hard hopefully that'll work. The problem with Avisynth plugins is there's often many versions of each and different flavours of each version.... but if I've got it right you should be able to check the "Use Avisyth Filters" box and select a script from the drop down box marked "Preset". Go with the one called colorbars first. That's a built-in Avisynth function. If it doesn't work there's no way the rest will. If it's working, you should see colorbars instead of a video (they probably won't appear unless a video is playing). If it works, try the rest. Please report back to let me know how it went.

    Ha, ha it really works even if the 'soap opera effect' is not so visible as with similar software like Splash Pro (Motion²), but it works. Big thank you for the guide!

  5. I'm glad it worked. If you're still around.....

    I was reading a little about Interframe today and apparently Avisynth 2.6 MT is recommended. It seems you don't install it as such. You install Avisynth, then just replace the avisynth dll in the Windows system folder with the MT 2.6 version linked to in the doom9 thread.

    For all I know the SVP version of Avisynth might actually be the same one, only they're still calling it Avisynth 2.5.8, or maybe it's a different version again. If you're not having any problems then I'd leave things as they are, but if you do have problems when using Avisynth, give the 2.6 version I linked to above a go.
