P-frames, which stand for "predicted frames," have always existed in the middle space between I-frames, or "complete images," and B-frames, or "highly compressed bi-directional predicted frames" - and they provide a good middle-ground in terms of file size reduction and video quality. Learn more about I-frames (and IDRs) and B-frames here. They plays a critical role in video compression in video codecs like H.264/AVC, HEVC, and AV1 and let us see why.The compression power of P-frames mostly comes from their use of motion estimation. If we have a video sequence with slow and gradual movementᅳsay, a person talking with minimally changing surroundings...
