NSIsNotNil NSNegateBoolean NSIsNotNil HBFrameRateTransformer 2-pass encoding analyzes the entire source video before encoding. The information gathered enables the encoder to make more informed decisions about quality and data rate in Average Bitrate mode. NSIsNotNil NSNegateBoolean NSIsNotNil NSNegateBoolean NSNegateBoolean NSNegateBoolean NSIsNotNil HBVideoEncoderTransformer Constant Quality varies bitrate to ensure visual quality remains relatively consistent throughout the video. Adjust the quality slider to the right to increase quality or to the left to decrease quality, in small increments of plus or minus 1-2. Recommended values for the x264 and x265 encoders are RF 18-28. Higher quality settings may produce extremely large files. x264 is lossless at RF 0.

Sets and ensures compliance with the specified video compression standard profile. Overrides all other settings. auto Video encoder level. Sets and ensures compliance with the specified video compression standard level. Overrides all other settings. auto Fast Decode uses settings that reduce CPU usage during playback of the encoded video. Useful for devices that struggle to play video without stuttering.
