After installing Kdenlive I tried glaxnimate from Store, from deb package, and from snap. After every install I changed the path in the 'Default Apps' configuration in 'Configure - Kdenlive'. The 'create animation' clip menu item remains greyed out.
At this stage I have the snap install of Glaxnimate, with three possible different paths I selected (closing and restarting Kdenlive after each path selection change), but to not avail.
STEPS TO REPRODUCE
1. Install kdenlive
2. Install Glaxnimate, start application.
3. Select the various paths showing a program with a wheel icon.
4. Closing and restarting kdenlive, reopen recent project.
5. Trying to 'create animation';
Clip menu item 'create animation' remains greyed out.
Clip menu item 'create animation' should be active.
Linux Ubuntu 22.04.1 LTS | Gnome Version 42.4 | Windowing System X11
Paths tested where the Glaxnimate app with a wheel icon is seen:

By the way the Glaxnimate snap install crashed repeatedly, so that I reverted to the deb package install that is stable.
This version has only one app with the wheel icon in usr/bin, which is the path I set in Kdenlive, but no effect.

Thanks for your report!
It seems you are using the Snap version of Kdenlive. This is a packing issue with Snap. You need to have a MLT version that includes the Glaxnimate module [MLT is a dependency of Kdenlive providing the media backend]. Whether you set the path to glaxnimate or not is unrelated in this case.
You can work around this issue by using the Kdenlive Appimage or Flatpak from www.kdenlive.org/download, for both it is guaranteed that they contain a MLT with all features enabled.
Technical info: mlt needs to get build with the cmake flag -DMOD_GLAXNIMATE=ON
Indeed, this works. Thank you.
I am not used to an appimage or flatpack, which are actually not installed on the system.
It is not straightforward how to make it work and I am not the least knowledgeable person in such system and software matters and it took me many hours to figure out with your help.
It may be a good think to stress how to 'install' Kdenlive on Ubuntu in order to make it fully functional and working.
I don't get it about this instruction, did not need it as well: 'Technical info: mlt needs to get build with the cmake flag -DMOD_GLAXNIMATE=ON'.
In general you are good to go if you use one of the install methods from the offical download page at www.kdenlive.org/downloads. All other install methods are not maintained by the Kdenlive team, but someone else (usually the packagers of your OS). The snap version (which you used first) is maintained by the KDE Neon team.
The technical info is for whoever will fix this bug to have everything right at hand.
I am working on the snap.
Glaximate animations MLT module is now fixed in the latest snap. Please install 22.08.2 from the snap store. ( Will take a few minutes to show up )
