Advanced Topic 47 of 49 Graphics, Vision & Media
Video Codecs
Algorithms like H.264 compressing video.
How it works
Codecs (H.264, HEVC, AV1) use intra/inter prediction, motion vectors, transform coding and entropy coding (CABAC) to reach 50–100× compression; GOP structure sets keyframe spacing.
Where it is used
Streaming and conferencing.
Common pitfall
Encoding efficiency vs compute and patents.
Where it fits in the course
Video Codecs is topic 47 of 49 in Graphics, Vision & Media, rated Advanced. It follows Augmented and Virtual Reality. The next topic is Speech Recognition.
