[Kdenlive-devel] Feature for kdenlive....

Tue Jul 1 06:12:40 UTC 2014

I have never used that script.

http://quickgit.kde.org/?p=kdenlive.git

On there, is an http view of the git repo.
Towards the bottom, there are different heads than the master.
I clicked on "next" and then downloaded the latest snapshot.

Extracted it, compiled & installed it

However, if you wait a little while, master will change into "next" as
that is more stable.
The current master will then become something else, where most of the
big feature adds is happening.
