Baseline 

Level 

Levels specify the size of the video a decoder must be able to handle. They specify a 
maximum bit-rate for the video and a maximum number of macroblocks per second. 
Level numbers range from 1 to 5 with intermediate steps (e.g., 1.1, 1.2, 1.3 and etc). 
The table below provides a summary of maximum parameters supported by each 
H.264/AVC level.
