Magisto Video Editor
If you'd rather not confine your video editing exploits to the PC, Magisto offers a pretty fully featured mobile environment to flex your creative muscles on the go. The headline feature of the app though is the automatic editing, which analyses video and photos and then creates a video, containing transitions and effects, without you having to put in any work at all.
As the name suggests, this app is more about trimming your mobile videos into more manageable lengths, than full on editing, but it's still pretty useful. You can quickly turn video files into MP3s, grab specific video frames to share and add effects.
