What is the best video editor on Ubuntu for editing multi-format/multi-eco?

I have many video clips with different formats and I want to create a short movies by joining them. Most of the clips are taken with Nokia N8 and Lumia 800. I am using Ubuntu, I have tried many of editors but I can not edit/video clips due to different video formats. Which open source editor should I use to achieve following tasks:

• Join different vidoe formats/encoding to produce on single movie
• Export to different formats (.avi, youtube, etc)
• Add texts on the clips and insert images

I don't want to install and try many of them.

Solution 1:

You could try OpenShot, which has also got some 3D Blender animations for titles, but it can be a bit frustrating. Other user-friendly options are PiTiVI and Kdenlive. As far as I've used them, you can easily join clips, insert text and images and export videos to different formats. There is a list of open-source editing software on Wikipedia.

Within a few months Lightworks, a very professional editor, should be available for Ubuntu.

edit: Lightworks is now available for Ubuntu

Solution 2:

I would recommend OpenShot. This blog post talks about it a little. It is able to use various video file types to create a small movie.
