The H.264 Analyzer provides a comprehensive reconstruction of the entire bit transformation process leading to the final picture. It begins with an examination of the picture partitioning structure and coding flow, including tiles, slices, and subpictures, followed by an analysis of CTU partitioning with recurrent splits.
The analyzer addresses key questions, such as the type of prediction used, the motion vectors, the selected prediction line, and the transformation formula. It visually and numerically displays elements like SAO, ALF, and deblocking filters. This detailed insight helps in identifying the efficiency (or inefficiency) of the coding process.
