H.264 - Codec / Extra

Trellis

Enable trellis searched quantization.

Macroblock provides a good compromise between speed and efficiency.

• Disabled
• Final MB (only on the final encode of a macroblock )
• Always (on all mode decisions )

CABAC

CABAC (Context Adaptive Binary Arithmetic Coding) a method of encoding stream syntax which results in high compression

No Fast PSkip

Disables p-frame skip detection - slightly increases quality, particularly in low detail areas, such as dark walls and sky.

No DCT Decimation

Disables DCT block decimation.

PSNR

Enables PSNR calculations that are reported on completion at the cost of a small decrease in speed

SSIM

Enables SSIM calculations that are reported on completion at the cost of a small decrease in speed
