KdenLive: Nothing is being rendered on Windows? Let's start off from the beginning: I have already configured KdenLive to point to the melt.exe file, and all the other proper plugins to allow rendering.

When I hit "Render" and try to render to a file, I am told that it has started to render, and then I am instantly told that the render completed successfully, in 00:00:00. However, there's nothing saved to disk.

I tried analyzing the script that generates when you select "Generate Script". It seems to be giving a "usage" dialog due to incorrect parameters. I'm wondering if maybe this is the problem. It reads as follows:

C:\Users\b4ux1\Documents\Vlogs\2017-10-22&gt;"E:/Kdenlive-

Kdenlive video renderer for MLT.
Usage: kdenlive_render [-erase] [-kuiserver] [-locale:LOCALE] [in=pos] 
[out=pos] [render] [profile] [rendermodule] [player] [src] [dest] [[arg1] 
[arg2] ...]
  -erase: if that parameter is present, src file will be erased at the end
  -kuiserver: if that parameter is present, use KDE job tracker
  -locale:LOCALE : set a locale for rendering. For example, -locale:fr_FR.UTF-8 will use a french locale (comma as numeric separator)
  in=pos: start rendering at frame pos
  out=pos: end rendering at frame pos
  render: path to MLT melt renderer
  profile: the MLT video profile
  rendermodule: the MLT consumer used for rendering, usually it is avformat
  player: path to video player to play when rendering is over, use '-' to disable playing
  src: source file (usually MLT XML)
  dest: destination file
  args: space separated libavformat arguments
I was having the same problem. Found this fix from the bug reports.  I did it all, exactly as it says, including the part that changes the melt directory in the program as opposed to moving the melt file to match the directory, and it worked. I did not lose my saved project that previously wouldn't render. It's saved in a different location and keeping it did not effect the fix.
