NASA LIVE: “EARTH FROM SPACE”
The video you posted is a compilation from the High Definition Earth Viewing (HDEV) experiment aboard the ISS.
Four commercial-off-the-shelf high definition video cameras are mounted outside the Columbus. Module enclosed in a pressurized and temperature controlled housing. The four cameras are oriented in different directions. (1 looking forward, 1 looking nearly straight down, and 2 looking back). They change from one camera to the next in a repeating cycle.
As C Stuart Hardwick notes the HD cameras provide much better images than the original standard definition remote controlled cameras still in use outside the ISS.
A live video stream from HDEV with a map showing the ISS location is available…
