Hi,

I'm currently using three different versions of kdenlive under Ubuntu 18.04, 

- 17.12.3    coming with Ubuntu 18.04 as a regular package
- 18.04.1    as an appimage taken from the kdenlive download page
- 18.08.b18  as an appimage taken from the kdenlive download page

with both appimages I noticed, that some of the frei0r plugins, although included in the appimages file system and read at program start (revealed through strace) are not offered in the selection menu for effects, i.e. face blur and face detection, and maybe more. That's the two where I noticed they're missing. 

On the other hand, the plugin mechanism is not completely broken. Other frei0r plugins like emboss are found. 


regards

frei0r effects

The two plugins you mentioned are blacklisted from the MLT Framework right now because they are not threadsafe.

https://github.com/mltframework/mlt/blob/v6.10.0/src/modules/frei0r/not_thread_safe.txt

Many frei0r effects are currently available through kdenlive as you can see here:

https://cgit.kde.org/kdenlive.git/tree/data/kdenliveeffectscategory.rc?h=v18.08.1

For example, the Posterize effect is available under the Artistic group.

We did put many unsafe effects in a separate category to "hide" them, but they should be still accessible for compatibility.
