MPEG-2 Video

The MPEG-2 format supports the following encoder properties:

Property	Type	Description
`BitRate`	integer	Average bit rate in bits/second.
`Profile`	enum	`main` `high` `422`
`Level`	enum	`low` `main` `high1440` `high`
`Chroma`	enum	`420` `422`
`N`	integer	Distance between successive I frames (determines the number of frames in the GOP.
`M`	integer	Distance between successive reference (I or P) frames (determines the number of B frames).
`ClosedGop`	boolean	Indicates that each GOP should be closed (no reference to frames in a previous GOP)..
`StartWithIFrame`	boolean	Indicates that the first frame (in coded order) must be and I frame.

HD 4:2:0 35 Mbps

Format	Description
