Blu-ray discs (BD) are designed specifically for the capacity of feature films in high resolution: high definition (1080p) or ultra high definition (2160p). With a storage capacity of approximately 25 GB, there is enough room for these types of video files in high quality. It is even possible to write different layers on top of each other, each with a capacity of 75GB. That way one disk can hold over 150 GB. Do you want to etch a family video on a Blu-ray? That is possible! You can overwrite the BD-R (Recordable) and BD-RE (Recordable Erasable) yourself.
