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.
