Hi everyone, is it possible to make a simple matte, luma or alpha, without track?
is there only track matte?
it seems to me very limiting.

You're right.  The Pr Track Matte effect is very limiting.  It's one of my perpetual complaints.  If only the developers of Pr could duplicate Ae's implementation of mattes, it would be a wonderful thing.  Or, do what FCP has been doing for years (decades?), which is incorporating them into the Transfer Modes.  I guess it's either too hard for them, or there isn't as much demand for advanced professional track matting as there is for dumbing down Pr as much as possible for Tik Tok creators.

Ann Bens provided the only way I know to prevent the matte being transformed with the layer being matted.  

It's possible to make traveling mattes in Nests, but separating them from the host timeline presents challenges with animating and keyframing.  It's not impossible.  It just requires some back and forth between nests and timeline in many cases.  Most users advise using Ae for more complicated track mattes.

You can draw any shape you want.

Both image and shape can be independently keyframed.

The opacity effect on clips has a mask feature like most effects do.

If using a graphics clip there is a mask system that you can do with layers in the same graphic.

There are a bunch of other matte efect in Effects > Obsolete but most mattes take information from another track it has to take the alpha or luma from somewhere.

More information on the effect you are trying to achieve would allow people to provide better suggestions.
