Video codecs are designed to remove vast amounts of spatial and temporal redundancy using complex mathematical properties, often requiring significantly more computational power for compression than decompression. This asymmetry is justified because files are compressed once but viewed many times, and codecs must also incorporate error resilience for streams that lose packets.
Impact: High. The intricate nature of codecs, balancing compression efficiency with perceptual quality and error resilience, underscores the sophisticated engineering required for modern video delivery.
In the source video, this keypoint occurs from 00:25:01 to 00:27:01.
