I have two suggestions:
- OpenShot: a light, easy, full-featured video editor for Linux. You can use it to make some simpler projects.
Pros: extremely easy to use, intuitive, user-friendly, stable.
Cons: lacks a few advanced options for professional edition, such as audio waves. Its keyframe system is pretty poor.
Installation: in a terminal, run sudo apt-get install openshot frei0r-plugins
.
- KDEnLive: an advanced video editor for Linux. It has an interface very similar to Openshot and is very good at professional video edition.
Pros: very modular (you can install plug-ins, edit your entire interface, etc.), stable, user-friendly, gets frequent updates (unlike Openshot), excellent for simple AND advanced tasks.
Cons: it's not as easy as Openshot, rendering times are long even with low settings (unlike Openshot), requires better hardware (crashes frequently if you have low RAM).
Installation: in a terminal, run sudo apt-get install kdenlive kde-runtime frei0r-plugins
.
I personally use Kdenlive because it suits all my needs, but used Openshot for a long time. If you need video compositing, you can also take a look at Natron and Lightworks.
