MJPEG movie recording has many benefits over h.264 recording, it places less demands on the CPU when compressing, which means less energy used, less heat generated & longer battery life.
Perhaps even a JPEG image sequence could be used instead? - this would get around the 4GB limit, (as each video is just a sequence of images).
