Tune optimizes the preset settings for the best quality depending on the type of the input video:

• Animation – for animated cartoons

• Grain – for grainy, detailed video material

• Stillimage – for still image footage

• PSNR  – for achieving high peak signal to noise ratio

• SSIM – optimization for structural similarity

• Fast Decode – for faster decoding

• Zero Latency – for streaming video.
