Description
Use of specified mode in
I/P/B frame
Enables/disables use of the spacial prediction modes for I, P, B frames.
Use out of picture MV
Enables/disables use in the motion predicion process of motion vectors over
picture boundaries.
Cb/Cr chroma qp offset
Specifies the quantization offset for Cb and Cr chroma components.
Quantizer for I/P/B slice
in CQ mode
Spesifies the quantizers for I-frames (reference frames), P-frames (predicted
frames) and B-frames (bidirectional predicted frames) in the CQ (Constant
Quantizer) mode.
Fix source/output frame
rate
Allows fixing the input and output frame rate values (for instance, when the
value specified in header is incorrect).
Use Aspect Ratio
Specifies the method of aspect ratio setting. The following methods are
available:
•
picture aspect ratio
•
sample aspect ratio
Sample Aspect Ratio
Sets one of standard aspect ratio or specifies the custom aspect ratio.
Write HRD parameters
Enables/disables the HRD model parameters writing into the encoded stream.
The HRD model maintenance is mandatory for the encoded stream
compatibility with various devices. And encoder tries to maintain the model,
even though the option is disabled.
Write Access Unit
Delimiter
Enables/disables the Access Unit delimiters (not obligatory) writing into the
encoded stream.
Write End of Sequence
Enables/disables the Sequence End Code writing into the encoded stream.
Write Closed Captions
Enables/disables the Closed Captions keeping (if CC are contained in the input
MPEG-2 or AVC/H.264 stream) in the output AVC/H.264 stream.
