Stuffing Bits into VBR StreamEnabling this option for VBR streams instructs the Encoder to “insert bits” for scenes in which the bitrate is below the specified minimum bitrate
TargetUHD Blu-ray Primary
ModeSingle Pass CBR, VBR, Analysis
Multi Pass CBR, VBR
BitrateSpecify Average, Minimum and Maximum encoding bitrates
Adaptive Q. MatrixAchieve highest picture quality without time consuming adjustments to the Quantize Matrix
Video ES CheckVideo Elementary Stream (ES) check function can be used to identify and verify the data integrity of your created Video Elementary Stream
ProRes Source CheckAbility to run a quick check of the header for your ProRes Sources
ProRes Source Check DetailedAbility to run a detailed check of your entire ProRes Source
[Segment Settings]    ScreenshotAutomatically inserts an I-frame at the scene change
I-Frame InsertionAbility to change the frame you specify to an I-frame
Editing Quantize Matrix    ScreenshotAbility to edit Quantize Matrix
CodingAbility to encode for Multi-Angle
Strong Intra Reference FilterA method of "intra-prediction" in which coded reference pixels are smoothed out to reduce contouring artifacts caused by edges in reference sample arrays
Chroma QP Index OffsetThis adaptive function enables you to control CQPO for more Luminance (positive values) or more Chroma (negative values)

Multi-functional Filter Sets:
Proprietary Pre-filteringDithering, Error Diffusion, Pixel Values, Black Level, Q. Characteristics, Luminance, Quantize, Grain, Texture, Spike, Blur, Low Pass, High Gain, Region
Pre-filtering with PreviewThe Preview function enables the user to apply a Filter while confirming the visual effect in real time
Adaptive Noise Reduction (NR)This function detects and removes source grain and re-creates grain for better compression efficiency
Q. Picture typeAlso known as IPB weights, this function specifies the limits for "B" and "P" picture distortion ratio to the "I" picture. This function is important for picture quality constancy in some cases
Anti OvershootAnti Overshoot added to Filter #2 settings window. This feature was added to remove side effects when using Low Pass Filters/em>
MIX Parameter added to Texture and Spike SettingsA new MIX parameter was added to Texture and Spike Non Linear Filter settings. This allows Texture and Spike to match more closely to original source grains
High Bit Processing and Q.RestrictNEW FEATURE: The HBP filter when used with "Restict" setting, allows the user to specify settings that greatly help reduce mosquito noise around titling
[Effect Settings]    ScreenshotSpecial Effects such as Monochrome, Black, Super Black,
Effect Windowand White. Also for applying a specified Matte
Effect Window With PreviewThe Preview function enables the user to apply a Special Effect while confirming the visual effect in real time.

Segment Re-EncodingRe-Encodes just a segment you specify. Also perform Multiple pass Segment Re-Encoding and Batch Segment Re-Encoding
Bitrate and Quantization Scale GraphAbility to see bitrate fluctuations or quantization scale on the graph and optimize the structure of each GOP
Additional Features    Screenshot 1 Screenshot 2
Setting Pictures' Temporal PositionSpecify and displays pictures' current temporal location. A-B function allows the user to set the temporal range of A-B pictures and to handle the range efficiently.
Recoding Pictures' Temporal PositionTimecode or frame entry and chase scratch pad
Playback Functions and Jump ControlsExtensive variable picture review playback controls and speeds
Frame Finder    ScreenshotFrame Finder is used to find a frame by scanning pictures with a slider control (Scrubbing)
