Which is better for bd and dvd?

Question: I want to download a few movies, see the DVD version, and the BD version. I am clear about the DVD version, but what is BD? Which is better for bd and dvd?

Answer: BD is definitely good, BD is the abbreviation of Blu-ray Disc, which is Blu-ray, the resolution of Blu-ray is full HD, reaching 1920× 1080, far exceeding the resolution of DVD 720× 480 .

We call the resolution of the DVD 480P, while the Blu-ray is 1080P, and some will be called BDrip. This is compressed by the BD original, which is 720P.

Under normal circumstances, 480P can be said to be standard definition, while 720P is high definition, 1080P is true HD.

Digital Versatile Disc (DVD), a kind of optical disc memory, is usually used to play movies with standard TV resolution, high-quality music and large-capacity storage data. .

Blu-ray Disc (BD) is one of the next-generation disc formats after DVD, which stores high-quality audio and video and high-capacity data storage. The name of the Blu-ray disc is due to its use of a blue laser beam with a wavelength of 405 nanometers (nm) for reading and writing (DVD uses a 650 nm wavelength red light reader and CD uses a 780 nm wavelength). A single-layer Blu-ray disc with a capacity of 25 or 27GB is enough to record a high-resolution movie for up to 4 hours.
