For those without AE I think an alpha render would be a good alternative.
Looks great, Luka!
I agree with what others have said about applying it to the original and let others add LUTs and other version tweaks.
If you do go the Alpha route, though, make sure you set the alpha to “straight” in the render settings, otherwise it won’t blend well with the footage underneath. If you’re using video copilot’s saber effect, the rendered file with the alpha channel may also blend differently that than it did in AE. You may need to test it in premiere to see if you need to set a blending mode (“add” or “screen” would be my guess) to better merge it with whatever footage is put underneath.
