Glaxnimate works with vector graphics, this means images are described with objects like lines, curves, and points. This is different from the more common raster graphics where you have a grid of pixels of different colors. An advantage of using vector graphics is that you can view the image at any resolution without losing quality. You can learn more about this in the Vector Graphics article on Wikipedia.
When animating vector graphics, you have the option of automatically generating smooth transitions between poses, in the process known as “Tweening” (or Inbetweening). The term comes from the action of adding frames in between two “key” frames that define the start and end of the animation. Glaxnimate allows you to do just this: you specify shapes and properties for each keyframe and the animation is automatically created from those. You can learn more about this technique in the Inbetweening article on Wikipedia.
Layers are used to group shapes and objects to have a more organized layout in a file. Glaxnimate supports having multiple layers and layers nested inside other layers, giving flexibility on how the file is structured. You can easily convert between layers and groups, the main difference is that groups are considered individual objects while layers aren’t. You can also read the manual page on Groups and Layers for a more in-depth explanation.
Precompositions are animations within another animation. You can use it to animate an element once, and then make it appear in multiple places using Precomposition Layers. When you modify the precomposition, the changes are reflected to all layers that point to that composition so you don’t have to apply the changed to every instance. With precompositions you can also change when the animation starts and its duration. This gives you the ability of creating elements that have looping animations simply by creating multiple precomposition layers with different start times.

@trom This is sooo cool and it integrates with Kdenlive! 😀
