Yesterday, YouTube launched a new video editor. It's a simple tool that allows you to upload raw video files then trim them down. You can also use the video editor to create mash-ups of the videos you've uploaded to YouTube. The editor also allows you to add soundtracks to your videos. Below you'll see a short tutorial I made about how to use YouTube's video editor.

AudioSwap is the new YouTube music gallery that you can use to add to soundtracks to your videos. It's important to note that any soundtrack you add to your video will override your original audio. Learn more about AudioSwap in the video below.
