VideoWriter Options
• Compression Ratio is a 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. The data is compressed as much as possible, up to the
specified target. This is only available for objects associated with Motion JPEG
2000 files. The default is 10.
• Frame Rate is the rate of playback for the video in frames per second. The
default is 30.
• Lossless Compression is a Boolean value (logical true or false) only
available for objects associated with Motion JPEG 2000 files. If you select true,
VideoWriter uses reversible mode so that the decompressed data is identical to
the input data, and ignores any specified value for CompressionRatio. The
default is false for the Motion JPEG 2000 profile, and true for the Archival
profile.
• MJ2 Bit Depth is the number of least significant bits in the input image data,
from 1 to 16. This is only available for objects associated with Motion JPEG 2000
files. If you do not specify a value, VideoWriter sets the bit depth based on the
input data type. For example, if the input data is an array of uint8 or int8 values,
MJ2BitDepth is 8.
