If the original YouTube or Vimeo video used in an interactive video lesson is removed, the lesson will no longer play. The interactivity still exists, but the lesson cannot be viewed because Zaption streams all of the videos directly from the host each time a lesson is played. However, none of the lesson Analytics should be lost.
When using videos that you do not own, there is always a risk that the video will be removed. We find this happens very rarely if the video is not infringing on copyright. We recommend using video from reputable sources and publishers, including these YouTube channels.
