Perhaps the Ubuntu Studio 12.04 version makes the difference. I will try it to test if there are any differences.
Does anyone know if the git and the ppa Cinelerra are the same at the moment? ________________________________ David Armstrong <[email protected]> wrote: I am running 64 bit Ubuntu Studio 12.04 Have installed the pre-compiled ppa version.
