Reduced Frame Quantization in Video Coding
[chapter]
2006
Lecture Notes in Computer Science
Preserved Fulltext
We vary the quantization parameter in H.264 video encoding by increasing it by a well-chosen offset in every other frame, which we call reduced frames. ...
As the motion compensation for a reduced frame is performed mainly from the previous frame (which is non-reduced), we obtain a large reduction in bit rate with only a small loss in video quality. ...
The total bit rate is reduced in average by 6% at low bit rates, and up to 18% with some video sequences which contain only little motion. ...
