array of`audiovideo.writer.ProfileInfo`objects

Supported profiles and video file formats, returned as an array ofaudiovideo.writer.ProfileInfoobjects, which have the following read-only properties.

Property	Description
`Name`	特征向量印度语的ating the profile name, such as`'Uncompressed AVI'`.
`Description`	特征向量印度语的ating the description of the profile.
`FileExtensions`	Cell array of character vectors containing file extensions supported by the file format.
`ColorChannels`	每个输出视频框架中的颜色通道数。
`CompressionRatio`	Number greater than 1 that specifies the target ratio between the number of bytes in the input image and the number of bytes in the compressed image. Only applies to objects associated with Motion JPEG 2000 files. Default:`10`.
`FrameRate`	Rate of playback for the video in frames per second. Default:`30`.
`LosslessCompression`	Boolean value (logical`true`或者`false`) that specifies whether to use reversible mode, so that the decompressed data is identical to the input data. When`true`,`VideoWriter`ignores values for`CompressionRatio`. Only applies to objects associated with Motion JPEG 2000 files.
`MJ2BitDepth`	Number of least-significant bits in the input image data, from 1 to 16. Applied only to objects associated with Motion JPEG 2000 files.
`Quality`	Number from 0 through 100. Higher values correspond to higher quality video and larger files. Only applies to objects associated with the`mpeg - 4`或者`Motion JPEG AVI`轮廓。Default:`75`.
`VideoBitsPerPixel`	Number of bits per pixel in each output video frame.
`VideoCompressionMethod`	特征向量印度语的ating the type of video compression, such as`'None'`或者`'Motion JPEG'`.
