Average brightness shift diagrams

These diagrams show average shift of brightness produced by the codecs. Coordinates of the basic points represent average brightness values for the whole sequence and the number of measurement (bit rate). So each branch contains ten points that correspond to different bit rates.

Bit rate handling diagrams

These diagrams show how codecs handle different bit rates. Every branch consists of ten points that correspond to different bit rates. Value “1” means that the codec keeps the specified bit rate; value more than “1” means that the codec actually compresses with the higher bit rate than was specified.

Per frame sequences comparison

These diagrams show how compression quality changes from frame to frame. X-axis coordinate represents the number of the frame and Y-axis coordinate represents PSNR-value for this frame. Significant constant difference on the susidi diagram is caused by the noise suppression in every second frame (B-frames options in MPEG-2 coder).

Visual comparison of H.264 and DivX codecs

Bbc3di sequence, frame 280

The following examples demonstrate better image quality after compression with the H.264 codec in comparison with DivX.

Picture 48. Bbc3di frame 280. Ateme Picture 49. Bbc3di frame 280. DivX
Picture 50. Bbc3di frame 280. Ateme Picture 51. Bbc3di frame 280. DivX

Foreman sequence, frames 282 and 9

The following examples demonstrate better image quality after compression with the H.264 codec in comparison with DivX.

Conclusion:

The following examples demonstrate close results from the image quality point of view for DivX and H.264.
