First, I use kdenlive-20.08.1-x86_64.appimage.


Kdenlive use alpha of png(alpha) well without compositor. (Maybe any alpha image)

But it cannot use alpha of Prores4444(Maybe any alpha video) without a compositor.


If you use any compositor, you can easily use it for VFX, but it's annoying.

Is this the right feature that developers want??

When you create a burning effect with Blender, create an animation with synfig, and then try to do something with kdenlive, annoying things happen.
