![]() no-weightb: H.264 allows you to 'weight' references in B-frames, which allows you to change how much each reference affects the predicted picture.Setting scenecut to 0 is equivalent to setting no-scenecut. scenecut: sets the threshold for I/IDR frame placement.These blocks can be further split up into smaller partitions, which is what this option controls. partitions: H.264 video is split up into 16x16 macroblocks during compression.This setting controls how x264 decides between placing a P- or B-frame. b-adapt: set the adaptive B-frame placement decision algorithm.This can lead to significantly better efficiency in terms of compression ratio. B-frames are similar to P-frames, except they can use motion prediction from future frames as well. bframes: sets the maximum number of concurrent B-frames that x264 can use. ![]() Context-adaptive binary arithmetic coding (CABAC) is a form of entropy encoding, not available when using ultrafast.
