In one of our projects we have been wanting to tag various places within videos. Here area few of the options that emerged.
1. You can within Youtube, link to a specific time within a YouTube video:
Thanks to RMIT’s Youtube communities expert Blair Wilde for this last solution.
2. Tubechop is a service that helps you cut out sections in YouTube videos. It makes available a link and embed code for the new section of video you have created.
3. Video notes is an open source platform that allows you to timestamp notes against a YouTube video. All the notes you type are automatically synchronised with the video. Later you can just click on a line for the video to jump to the relevant part.
