**3. How H.264 Works: A Closer Look at the Video Codec**
H.264, also known as Advanced Video Coding (AVC), is a widely used video codec that provides efficient compression without significant loss in video quality. It uses the concept of inter-frame prediction, where only the differences between frames are encoded, resulting in smaller file sizes. This encoding technique is commonly referred to as “temporal compression.”
H.264 divides video frames into groups of pictures (GOP), with each GOP consisting of an “I-frame” followed by multiple “P-frames” and “B-frames.” The I-frame, or keyframe, is a complete image that doesn’t rely on any other frame for reference. P-frames (Predicted frames) rely on previously coded I-frames or P-frames, while B-frames (Bidirectional predicted frames) can refer to both preceding and following frames for enhanced compression efficiency.
By analyzing the differences between frames and encoding only the changes, H.264 achieves high-quality video compression. It also supports a wide range of resolutions, from low-definition to high-definition, making it suitable for various applications such as video streaming and digital television broadcasting.
Due to its effectiveness in compressing video data, H.264 has become a popular codec for encoding videos in the widely supported MP4 container format. Its efficient compression techniques enable smooth streaming and playback across different devices and platforms.
