YouTube has just put out a new Web based application called CaptionTube that lets users add text captions to their videos . The video service has had support for captioning in its videos since August of last year, but until now you’ve been stuck having to do it with time codes and captions uploaded as a separate .SUB file. This new system, which will be a part of YouTube’s TestTube labs section , lets you add captions right in your browser using a timeline-based system that looks and feels like a video editor. The tool lets you grab videos either from your own YouTube uploads or any other YouTube video via its URL. You can then start adding captions in a similar fashion to YouTube’s on-screen annotation editor, selecting how long you want each caption to appear by picking specific beginning and end points. You can also create and edit multiple languages of captions at the same time, which show up as separate tracks in the timeline. CaptionTube lets you add captions to your videos right inside
