If you refer to the green soldermask in the video, that is real soldermask for industrial PCB making. However, the last shot on the finished PCB shows very poor finish, because is almost for sure that the datasheet for that soldermask states that it must be baked in an air-forced oven before imaging with UV. Also, it must be applied by screen printing, not manually with a card. If the user follows all the steps according to the manufacturer you end with a professional board, since the soldermask in the video is "the real thing" used in industry.
