14 DAY TRIAL // In case you have a video which you plan to upload on YouTube but it needs some extra editing to be more attractive, it is not always a good idea to install a professional application with very complex functions. First of all, you don't know how to use it. Secondly, the editing process might be very complex and it might require a lot of time. That's why I recommend you Remixer. In fact, it's YouTube Remixer because it is powered by the famous online video sharing service owned by Google. So, what's Remixer? Well, it's anything you want if you intend to edit your clips, insert photos, sounds and even other videos. Obviously, it is accessible through a web-based interface so no installation is required.
"If you've ever uploaded from your cell phone, wished for an easy way to add titles and transitions, or just wanted to remix your own videos, Remixer is a great place to play. It lets you assemble your new video in an easy drag-and-drop timeline, and then publish it right back to YouTube. Your original videos will stay exactly the same," it is mentioned on the official page of Remixer.
All right, how can I use it? At this time, YouTube Remixer can be enabled straight through this link or by following these steps: login into your YouTube account, click on the My Videos link and press the Remix Video button located near the uploaded clips. "You can start using Remixer by dragging content from the "My Videos" media bin on the right into the main viewing window or the timeline below it. Once you've placed content within the editor, you can edit, transition and remix that content. In addition, you can layer captions, borders, or other graphics over the content and try out different soundtracks. You can do all of this from within Remixer simply by dragging and dropping content from the media bins into the appropriate areas of the editor," YouTube wrote in the 'How to use Remixer' section.
Keep in mind that you're able to remix only your uploaded clips because the copyright over other YouTube clips does not allow you to modify others' videos.
