Video is a series of photos. Captured by the photo sensor identically to taking photos, but for bandwidth and time reasons usually downsampled and with a max exposure time of the framerate. In low light that 30 FPS camera will increase the exposure time to up to 1/30th of a second. In a bouncing, rapidly changing camera this yields a smear of a photo. OIS combats this by limiting capture motion during most movements. There is absolutely an enormous difference between the two, and it yields the classic garbage in = garbage out problem.
