YouTube: Now you can edit your videos online!

Starting September 2011, YouTube now allows you to directly edit your video online. This is especially useful for those of us who upload iPhone or other mobile phone-based videos and don't want to go through the added step of DOWNloading our video, doing minor edits, and then before UPloading to YouTube.

They really capture the primary features which you really need:

• Trimming the video (start and end)
• Rotating the video
• Manually changing the brightness and contrast
