Pleased to present a new ppa for Kdenlive stable series : at this moment 0.7.8 : ppa:sunab/kdenlive-release
See the download section of this website for more information.
Note : All packages are built against the standard KDE and standard FFmpeg in each Ubuntu version, so if you are using a backported KDE or backported FFmpeg, DO NOT USE THIS PPA or you will experience many problems.
P.S. : For users (knowing what they do!) who want to follow kdenlive development there is also a new ppa to track svn : ppa:sunab/kdenlive-svn (weekly build)
Use it to test kdenlive and file bug reports if needed on the mantis bug tracker. For this ppa same note as previous ppa : NO BACKPORTS.
Edit : FFmpeg recommendation
*for jaunty : a custom ffmpeg is included in my repositories (+libfaac) / webm unsupported
*for Karmic : a custom ffmpeg is included in my repositories (+libfaac) / webm unsupported
*for Lucid : use official Ubuntu repositories or the Medibuntu project repository "deb http://packages.medibuntu.org/ lucid free non-free" (+libfaac+amr) / webm unsupported
*for Maverick : use official Ubuntu repositories, an internal acc encoder is activated in ffmpeg 0.6 series.
Note 2 : My kdenlive packages force installation of -extra ffmpeg libraries in order to maximize codecs support, this is an "ugly" packaging but it is more simple for newcomers.
Edit 2 : Frei0r 1.2.0 is packaged for Maverick and Lucid.
