Google introduced YouTube?s new online video editor, which makes editing of video easier without needing to install any external software. Available in TestTube, the new video editor allows users to combine multiple videos they've uploaded to create a new longer video, trim the beginning and/or ending of their videos, add soundtracks from Google's AudioSwap library of songs and also create new videos without worrying about file formats and publish them to YouTube with one click?no upload necessary.
