Level

When converting animated GIFs to the MP4 format and when used in conjunction with the profile parameter, the level parameter specifies a set of constraints indicating a degree of required decoder performance for a profile.

NOTE: If either level or profile parameters are missing, profile=baseline&level=3.0 will be used as the default.

enum Level {
  LEVEL_1_0
  LEVEL_1_1
  LEVEL_1_2
  LEVEL_2_0
  LEVEL_2_1
  LEVEL_2_2
  LEVEL_3_0

  LEVEL_5_0
