存储未压缩视频所需的数据量

1. A single frame of high definition (1920x1080) video in full color (4 bytes per pixel) is 8,294,400 bytes.
2. At a typical 30 frames per second, each second of HD video would occupy 248,832,000 bytes (~249 MB).
3. A minute of HD video would need 14.93 GB of storage.
4. A fairly typical 30 minute video conference would need about 447.9 GB of storage, and a 2-hour movie would take almost 1.79 TB (that is, 1790 GB).
