Here is a simple patch for Cinelerra 4.5 from Heroine Virtual
The Source code is located here http://sourceforge.net/projects/heroines/
extract the archive and place the patch in the cinelerra-4.5 directory, open a terminal in that directory and
patch -p1 < cinelerra.patch
basically the speech_tools were not up to gcc standards
But that led to the problem that the package "libmpeg3cine" could not be installed because some files were already installed by package "mpeg3-utils". The package system seemed broken because of a defective package.
Phoronix: Cinelerra 4.5 Is Silently Available For Video Editing
Cinelerra, one of the popular open-source video editors and compositors for Linux, hadn't seen an official update since July of 2012 but pushed this week was a source package for their next major release...
I have googled for information relating to how to import or convert and load AVCHD (mts) HD files into cinelerra. Most of the threads are pre 2012 and being as its now nearly 2015, I am hoping things have improved.
I have to agree with the previous poster, cinelerra is the way to go, if you want or need professional capabilities.What's more is that cinelerra package is available within the standard CrunchBang repositories.
