KDenLive not working in Ubuntu 11.10

Could you tell how and from where did you try to install the Kdenlive ?

At here

From the Ubuntu repositories: http://packages.ubuntu.com/search?keywords=kdenlive&searchon=names&suite=oneiric&section=all

Package version is 0.8

Browsing to the Kdenlive home: http://www.kdenlive.org/

Binary section for Ubuntu: http://www.kdenlive.org/user-manual/downloading-and-installing-kdenlive/pre-compiled-packages/ubuntu-packages

They are recommending Sunab's PPA.

That is: https://launchpad.net/~sunab -> https://launchpad.net/~sunab/+archive/kdenlive-release

Adding the ppa:sunab/kdenlive-release:

sudo add-apt-repository ppa:sunab/kdenlive-release

Launching the Kdenlive...

Seems to work.

Edit - the libmlt++3/libmlt4/libmlt-data/melt version

The kdenlive, version: 0.8.2.1-0ubuntu0~sunab~oneiric1, is depending the libmlt++3/libmlt4/libmlt-data/melt, without any package version restrictions.

apt-cache show kdenlive

Package: kdenlive
Priority: optional
Section: video
Installed-Size: 4144
Maintainer: Olivier Banus <****>
Architecture: i386
Version: 0.8.2.1-0ubuntu0~sunab~oneiric1
...
Depends: ..., libmlt++3, libmlt4, ..., melt, libmlt-data, ...

If you have those installed then those won't be upgraded with the install kdenlive.

To fix this, run the upgrade:

sudo apt-get upgrade

or

sudo apt-get dist-upgrade

It should upgrade those packages to the latest version from the Sunab's PPA.

Other options

Is there any other video editing program that lets me cut a part of the video.

Yes there are many video editing programs. I'm using the Avidemux.

• Avidemux home: http://avidemux.berlios.de/

• Wiki: http://www.avidemux.org/admWiki/doku.php

It is available from the Ubuntu repositories:
