Welcome to TestTube, our ideas "incubator." This is where YouTube engineers and developers test out recipes and concoctions that aren't quite fully baked and invite you to tell us how they're coming along.
Your comments will help us improve and perfect the mixtures we're working on. So jump in, play around, and send your feedback directly to the brains behind the scenes.
Use Active Sharing to show other YouTube users what videos you're watching
Use AudioSwap to replace the audio on your videos with officially licensed music.
Use YouTube's Video Remixer to "remix" your videos with
text, audio, graphics, overlays, effects, and transitions.
Join Streams to chat with others who are watching the same video you are.
