iPhone 6 Plus - super slow motion 240 fps - low light test

We tested the super slow motion video recording on iPhone 6 Plus in real environment, indoors, with mixed light. There was LED light in the room, and minimal regular light from the side. The blinking in the video comes from the frequency off the light bulbs.
The image is noisy because to shoot video in 240 fps you need the shutter speed of 1/480s (or1/240s minimum) which limits the light available to the sensor so higher ISO must be used to achieve proper exposure.
