OpenShot: Video Editor

OpenShot is a new video editor which looks promising as it has made so much progress while it's still new in the open source region.

Features:
1) It claims to add almost any video and yes "flv" as well. (I tried mpg2, flv, mp4, mpg and all of these worked.)
2) Zoom in and zoom out (the length of video)
3) Multiple tracks (You can add by clicking the add button which is on the far left above the tracks.)
4) Split and resizing of videos - Makes video editing easier without the necessity to resize the track over and over again. (Use Razor, next to mouse button)
5) Video transitions
6) Add pictures, watermarks and overlays... (You can make a logo or something on Gimp and add it on a track 2 - which is above track 1 - the edited video and the logo will be on the video)
7) Multiple output format (Most output works but sadly right now YouTube HD output doesn't, I shall wait for fixed bugs but meanwhile I would use other output formats)
8) Support 32-bit and 64-bit.
9) Simple interface

When I installed OpenShot on my Ubuntu 9.04, I couldn't start OpenShot from the shorcut on desktop or the shorcut on the Gnome menu. Right click on the shorcut on the desktop and change the command to:
python /home/YOURNAME/openshot/openshot/openshot.py
YOURNAME should be the username of your system.
Then it works!!!

How to install on Ubuntu 9.10 Karmic Koala?
Open Terminal (Applications → Accessories → Terminal) and run the following commands:

sudo add-apt-repository ppa:openshot.developers/ppa

Then, it will ask your password, so key in your password and if you realise, the gpg key is automatically downloaded.

sudo apt-get update

It will then update to get the latest packages from the sources and now you're ready to download them.

sudo apt-get install openshot ffmpeg-extra frei0r-plugins melt python-support x264

After OpenShot is installed, find it on Applications → Sound & Video → OpenShot Video Editor
