Primary Output - Video Codecs
General
Video Bit Rate. Specifies the bit rate, per second.
Quantization Coefficient. Specifies quality (0-100). If set toward the lower range it
reduces data correspondingly and quality decreases; if set to the upper range it
increases data and quality. However, the default value of 0 (zero) applies no coefficient
(effectively disables the feature), resulting in the video being encoded at the full data
rate. Un-check the Use Default Quantization Coefficient option to enable this ability to
specify the quality.
Pixel Format. Specifies the color space, chroma subsampling, and bit depth to use for
encoding.
- RGB 4:4:4 8 bit or 10 bit @50,000 bp/s
- YUV 4:2:2 10 bit @50,000 bp/s
- YUV 4:2:2 8 bit @50,000 bp/s
Tile Partition Width. Specifies the tile partition width in pixels.
Tile Partition Height. Specifies the tile partition height in pixels.
Precinct Width and Height. Specifies the precinct size.
Code Block Width and Height. Specifies the height and width (in pixels) of a code
block to process.
Packet Progression. Specifies the order of packet progression.
Decomposition Levels. Specifies the Discrete Wavelet Transform resolution.
Tile-Part Length Markers. When checked, specifies that Tile Length Markers will be
used.
End of Packet Header Markers. When checked, EPH marker segments are generated.
Start of Packet Markers. When checked, Start of Packet marker segments are
generated.
CUDA Memory Limit. Specifies the CUDA memory limit in MB.
Note: When the CUDA Memory Limit is set to 0, GPU processing is disabled.
CUDA Tile Limit. Specifies the CUDA tile limit.
Encoder Queue Size. Specifies the encoder queue size.
