Changing video encoding advanced settings is at your own risk. Wrong settings may considerably impact video encoding performances and quality.
- Enable Frame Interpolation : Enable frame interpolation algorithm for i50/i59.94 to p50/p59.94 conversion
- Level mode: Video codec level
- Look ahead mode: The encoder attempts to foresee the content of the frames to make better encoding choices
- AUTO: Look ahead is automatically set by the encoder
- OFF: Look ahead is off
- ON: Look ahead is on
- Slice mode:
- AUTO: Number of slice per frame is automatically set by the encoder
- CUSTOM: User configurable number of slice per frame (depending on output resolution)
- B-picture mode:
- NONE: The encoder generated no B-frame
- AUTO: Number of consecutive B frame is automatically set by the encoder
- CUSTOM:
- Pyramidal B pictures: Use B pictures as reference (3 or 7)
- Number of B Pictures: User configurable fixed number of consecutive B frame
- Fixed Size GOP: Interval between two I-Frame is fixed
- Key Frame Alignement : IDR-Frames of all video profiles are aligned. Mandatory for Adaptive bitrate.
Supersede "IDR presence" setting
- IDR presence:
- NONE: No IDR (Instantaneous Decoding Refresh) in encoded stream
- PRESENT: Put an IDR every X GOP
- Buffer mode: Decoding buffer settings
- AUTO: Decoding buffer is computed automatically by the encoder
- CUSTOM:
- Buffer size in bits: Size of decoding buffer in bits
- Initial buffer size: Percentage of decoding buffer fullness before starting decoding
- Average Bitrate Window Mode
- Auto: Average bitrate window is automatically managed by the encoder to get best video quality (recommended)
- Custom: Average bitrate window is set by operator
- Deblocking filter: Video filter to smooth the sharp edges between blocks and improve appearance of decoded picture
- AUTO: Deblocking filter activation is automatically set by the encoder
- OFF: Deblocking filter activation is off
- ON: User configurable deblocking filter parameters
- Weighted Prediction P:
- AUTO: Weighted Prediction activation is automatically set by the encoder
- ON: Weighted Prediction is on
- OFF: Weighted Prediction is off
Enabling "Weighted Prediction P" considerably decreases video encoding performances.
- Weighted Prediction B:
- AUTO: Weighted Prediction activation is automatically set by the encoder
- ON: Weighted Prediction is on
- OFF: Weighted Prediction is off
Enabling "Weighted Prediction B" considerably decreases video encoding performances.
- Scaling list: Quantization scaling matrix
- OFF: Uniform quantification
- DEFAULT: Default quantification as defined in specification
- CUSTOM: Customized quantification
- AUTO: Scaling list mode is set automatically by the encoder
