Hi

I am trying to use the latest kdenlive 20.08.0 (installed or stand alone) in Windows 10 2004 x64, and the frei0r.pixeliz0r filter gives me troubles.

It works perfectly in the kdenlive preview and timeline, all dll seem to be well installed in
C:\Program Files\kdenlive\bin\data\kdenlive\effects
C:\Program Files\kdenlive\lib\frei0r-1
C:\Program Files\kdenlive\lib\mlt

However, when I render it to mp4 or webm, the filter does not show; it is simply inactive and ineffective, like no filter has been chosen, but without any error message as far as I can see.

How can I further debug the problem?

Best,

thn

From a shell accessing kdenlive/bin, try that command:
melt -query filter=frei0r.pixeliz0r
Does it show the effect metadata?
Also if you abort the rendering before end, you can check a .kdenlive.log file in %TEMP% folder that stores melt output (this fie is deleted upon complete render)

I get

I tested with another keyframeable frei0r filter, glow, and it is just the same: works in the editor, but seems to get dropped during rendering.

Any more ideas?

Can you share a sample project?
In your language, is the decimal separator comma "," or point "."?

In german [DE] it is the comma (one thousand would be 1.000,0)

Please find a sample project hereafter, pixelizing a still image over 5 seconds. Please insert the link to your sample image and your home directory (root), and change meta.media.width and height.

Well you hit the nail!

When I change the parameters used to call frei0r.pixeliz0r from "0.178" to "0,178" then the filter does no longer work in kdenlive BUT the mp4 compiles correctly with melt! Unfortunately, changing LC_NUMERIC to en_US does not change this behavior.

Is there a way to adjust the language settings so that both tools can collaborate?

OK, we tried to solve all these comma/point issues in 20.08, but obviously we're still not done yet with frei0r X(
I'm forwarding to the team, we'll try to fix this for 20.08.1 hopefully, maybe in MLT (melt)...
