I was able to run a (all be it minimal) kdenlive using some/all of the following commands in some order (I've probably missed a crucial one too). Your milage will vary.
My question is - given that it doesn't seem to hard to get things to work, is there any chance of providing a full prebuilt app for mac as some of the other KDE projects do?
In the meantime - to answer all those who seem to think it's hard, honestly - it seemed to be pretty straightforward to get things to work... Don't be scared by the long list of brew installs if you are seeing this and wondering if you should try. Really its not hard... (and please, somebody, clean this up and make it more appealing to people by all means !)

Cheers
Mark.

hi

our team doesn't have a maintainer for mac osx so we can't really help but contact the folks at macports which have a kdenlive version for mac. they seem to have some problems so maybe you can help them solve it:

thanks!
