A video streaming platform must choose between two encoding formats. Format A encodes quickly with moderate quality, producing larger files. Format B takes 2.7 times longer to encode but produces files half the size of Format A. Each time a video is streamed, the smaller file transfers less data over the network.
For a video that is expected to be viewed only twice, which format consumes less total energy (encoding plus all transmissions), and why?

 For a video that is expected to be viewed only twice, which format consumes less total energy (encoding plus all transmissions), and why?

Accepted Answer

Format A, because the higher encoding cost of Format B is not recovered by transmission savings over only two views

Answer

Format B, because smaller files always save more energy regardless of view count

Answer

Both formats consume the same total energy at two views

Answer

Format B, because encoding energy is negligible compared to transmission energy
