Sorry for taking so long. I tried to do the research by myself but after so many hours I haven’t been able to find the solution.
I rendered the file again as QT/Animation/Millions of Collors+/ Alpha Channel / Straight Alpha. And even though the file becomes a little bit more visible, it still missing color and becomes transparent.
This is the file already placed on a composition in Ae.

Now this is the same file when I toggle the transparency grid

It’s almost impossible to see, but it’s there. It’s like the opacity it’s being pull down to 1%
Now funny thing, this is the same file if I open it from QT player

Now this is a screenshot taken from C4

I’m still doing my research and trying different rendering options, but most of the time the outcome is the same…Here are some ss of my settings.
