David,

I have another question. Is there a plan for incorporating Cinelerra-gg like
a Debian official package?

Short answer -- we are not aware of it but there could be someone doing that.

There have been a couple of people interested in incorporating CinGG into various operating systems official package but in the case of Debian, we were provided with a set of fixes to our build procedure that would have helped them to get there but the fixes for 1 operating system did not necessarily apply to all the others. So it did not get done.

Recently we did find out that there is a Fedora Cinelerra package last updated December 2019. There also used to be an Arch one in its AUR.

In other words, I don't really know! Phyllis
