The .tga is not supported in Premiere Elements 11, 12, or 13.
You should be able to import it into Premiere Elements 10 Windows 7 64 bit.
What computer operating system is your Premiere Elements running on?
There is no codec download that I know of to allow tga imports into versions that do not support the file extension.
What is the source of these tga files?
What video card/graphics card does your computer use? If NVIDIA GeForce, then we need to talk about that. And, we
need to discuss other probably that you may be having with Premiere Elements 10 that might reflect on the 10 non support for
tga files that you have run into.
We will be watching for further details.
Photoshop elements 10 DOES support importing .tga files!
But that is not the issue. I found out the app with which I save the file saves it in the wrong way ( , Tga instead of .Tga)
I contacted their helpdesk.
