predicted frame (P-frame)

Predicted frames (P-frame) are predicted frames in MPEG compression based on the prediction and difference information of previous intra frames(I-frames) and previous predicted frames.

Predicted frames have a higher compression ratio than the intra frames, which can be as high as 20:1. Accordingly, the compressed data volume of a predicted frame is lower.

In the predicted frame, the fact that image details shift only slightly is taken into account. The displacement is stored as a motion vector.
