I want to create an animated lower third strap.
Problem is whenever i try and import a rendered bit of video the alpha channel cannot be recognised by after effects 5 or Premiere pro. I have tried exporting the alpha element and using that as a track matte but still not having much luck.
Which fileformat did you use for render output?
Which renderer did you use?
In general 3ds max cuts out everything, that is empty space or background. If you are using transparent materials, this is recognized. But if you are using any kind of raytracing for reflection/refraction it causes trouble.
