Public Properties
Name | Description | |
---|---|---|
ActualAspectRatio | Gets the actual aspect ratio of the video profile. Note that if you're using square pixels (when AutoFit equals true), the actual aspect ratio may be slightly different than the aspect ratio that is passed to the SetAspectRatio method, because the video frame dimensions are rounded to the nearest 4 or 16 pixels. (Inherited from VideoProfile) | |
AdaptiveBFrames | Gets or sets a value indicating whether sequence complexity determines B-frame placement. This value is ignored if H264 GPU encoding is enabled. | |
AspectRatio | Gets or sets the aspect ratio used to encode the profile. If set to null, the aspect ratio is controlled by the width and height of the stream. (Inherited from VideoProfile) | |
AutoFit | Gets or set a value indicating whether the output resolution is calculated by fitting the source media item within the profile's size. For example, if AutoFit is set to true and the profile is set to 320 x 240 with an aspect ratio of 16:9, the output size will be 320 x 180. If AutoFit is set to false, the output size will be 320 x 240 and the video will be encoded with non-square pixels. (Inherited from VideoProfile) | |
Bitrate | Gets or sets the bitrate to use when encoding. (Inherited from VideoProfile) | |
Codec | Overridden. Gets the codec type. | |
FastInterDecisions | Gets or sets a value indicating whether to apply faster coding decisions across frames to speed up encoding. | |
FastIntraDecisions | Gets or sets a value indicating whether to apply faster coding decisions per frame to speed up encoding. | |
Force16Pixels | Gets a value indicating whether auto-calculated dimensions are rounded to 16 pixels (true), or 4 pixels (false). (Inherited from VideoProfile) | |
FrameRate | Gets or sets the frame rate in frames per second. Zero (0) means that frame rate of the source file will be used. (Inherited from VideoProfile) | |
HadamardTransform | Gets or sets a value indicating whether Hadamard Transform mode is used. | |
InLoopFilter | Gets or sets a value indicating whether in-loop filtering is turned on. The in-loop filter reduces blocking artifacts during encoding to improve the quality of P-frames and B-frames. Note that the setting is ignored in H.264 as it is always enabled for quality reasons. | |
IsEditable | Gets a value indicating whether the profile can be modified. (Inherited from ProfileBase) | |
KeyFrameDistance | Overridden. Gets or sets the key frame distance in seconds. | |
MEPartitionLevel | Gets or sets the value for the ME Partition Level. This defines the complexity of the ME partition decision for inter-predicted frames. A smaller partition level means higher complexity and usually produces better compression capability (or better quality at the same bitrate). | |
MultiReferenceMotionSearchMode | Gets or sets a value indicating what MultiReference Motion Search mode is used | |
NumberOfEncoderThreads | Gets or sets the number of threads used by the encoder. Defaults to 0 to allow the encoder to choose a value based on the video and the number of logical processors available. (Inherited from VideoProfile) | |
RDOptimizationMode | Gets or sets a value indicating what RDOptimization mode is on | |
ReferenceBFrames | Gets or sets a value indicating whether ReferenceBFrames is turned on. This value is ignored if H264 GPU encoding is enabled. | |
ReferenceFrames | Gets or sets the number of reference frames for inter-predicted frames. | |
SceneChangeDetector | Gets or sets a value indicating whether key frames will automatically get created when a scene change is detected. | |
SearchRange | Gets or sets the search range in pixels. | |
SeparateFilesPerStream | Gets a value indicating whether a separate file is created for each stream. (Inherited from VideoProfile) | |
Size | Gets or sets the size of the video profile. (Inherited from VideoProfile) | |
SliceCount | Gets or sets a value indicating the number of slices per frame. Dividing the frames into more slices improves encoding speed but reduces quality because it prevents searches between slices. | |
SmoothStreaming | Gets or sets a value indicating whether the profile uses IIS Smooth Streaming. Note that if you're using VC-1, setting this property to true will cause the following properties to be set as follows: ClosedGop to true, AdaptiveGop to false, and OutputMode to ElementaryStreamSequenceHeader. When you are using Smooth Streaming, the bitrate of the streams must be either all ConstantBitrate or all VariableConstrainedBitrate. (Inherited from VideoProfile) | |
StreamCopyOnly | Gets a value indicating whether this profile supports only stream copying. This can happen if the decoder is installed but the encoder is not installed. (Inherited from ProfileBase) | |
Streams | Gets or sets the collection of streams. (Inherited from VideoProfile) | |
SubBlockMotionSearchMode | Gets or sets a value indicating what SubBlock Motion Search mode is used | |
SubPixelMode | Gets or sets a value indicating subpixel searching mode. Full depth is quicker but less accurate and Half and Quarter provides the best quality at the cost of encoding time. | |
XmlDescription | Gets the XML description of the profile if the profile was initialized from an XML profile string. (Inherited from ProfileBase) |
