Latest kdenlive
Greetings We have been using kdenlive on our production during the last 4-5 years. Before kdenlive we were using cinelerra Our setup is the standard ubuntu LTS version and kdenlive from the repositories. I note that the version we are working with is 15.x.x On the list you talk about version 19.x.x Would you recommend us to build our own updated version, and if so where should i take the source code from. We use the kdenlive in a production environment on about 20 PCs all running Ubuntu LTS and would like to have a somewhat stable version. We are, along with that, also happy to compile the occasional test version if the community needs it. We regularly build our own ffmpeg version Regards Mettavihari

Re: A story of a former Kdenlive's user (switched to Olive)
Greetings from Sri Lanka We are clear Open Source Users, started with Cinelerra some years ago, after that switched to Kdenlive with blender to support in the graphics. I still like the basic cinerella. Sure we will also try Olive, but at present we have close to 50 PCs running Ubuntu and Kdenlive. So thanks to all of you for staying alive. We do not talk much on the list, but at least you know that you have users, who are happy that you exist.

Re: Atelier Video in Brussels + Blackmagic Mini Monitor Output
Greetings We are also using kdenlive to capture from blackmagic. We look forward to have the December version with this facility back again Presently we stay with the older version that has this facility.
