Record a QuickTime movie with MSP audio
Use the jit.vcr object combine a sequence of Jitter matrices and MSP audio and save the sequence to disk as a synchronized QuickTime movie. The two left inlets accept MSP audio signals (if only 1 inlet is used, the movie's audio will be monophonic). The right inlet accepts a Jitter matrix.

More about Matrix Operators
The Jitter MOP
Since the matrix is Jitter's focus, it is not surprising that the majority of Jitter objects fall in this category of Matrix Operators. Every Matrix operator has some number of matrix inputs and some number of matrix outputs. Matrix inputs are referred to by the names "in", "in2", "in3", etc., from left to right, and matrix outputs are referred to by the names "out", "out2", "out3", etc., from left to right--i.e. the names are appended by the input/output number except for the first (leftmost) input and first (leftmost) output which are simply named "in" and "out". We will refer to the input or output name names as the "I/O-name".
Matrix inputs and outputs typically each have their own matrices internally where information is kept. This is necessary because Jitter is an asynchronous framework (i.e. all the matrices don't arrive at all inputs at the same time). Various aspects of matrix inputs and outputs can be set using the command [I/O-name] combined with one of the following suffixes: "_dim" which will set the dimensions of the specified I/O matrix, "_type" which will set the type of the specified matrix, "_planecount" which will set the plane of the specified matrix, or "_name" which will set the name of the specified matrix. There is one special case which does not have an internal matrix and this is the first input "in". This is the case since this special input actually triggers the calculation of the matrix operator, so it doesn't need to be cached until a calulation takes place, unlike the other inputs. Therefore there is no mechanism to set the dim, planecount, type, or name of "in".
Matrix operators accept what we'll refer to as "matrix args"--i.e.. if these arguments are present, the attribute will be turned off, otherwise it will be turned on. If adapt mode is turned on, each time a matrix is received in the first input, there will also be the equivalent of setting the , , and attributes to that of the input matrix. If the other inputs and outputs are linked to these attributes, this will affect their linked attributes as well. See the "MOP" table to determine which inputs and outputs will be linked to which attributes when adapt mode is turned on. For the leftmost input this is not applicable, and hence all columns are labelled "n/a".
The jit.matrix object is a named matrix which may be used to matrix data storage and retrieval, resampling, and matrix type and planecount conversion operations.
Explicitly sets the number of planes for the output and any righthand inputs. If this is absent, the Matrix Operator will typically adapt to the lefthand incoming matrix attributes, except for special case operators.
Explicitly sets the type of the matrix for the output and any righthand inputs. If this is absent, the Matrix Operator will typically adapt to the lefthand incoming matrix attributes, except for special case operators.
Explicitly sets the dimensions of the matrix for the output and any righthand inputs. If this is absent, the Matrix Operator will typically adapt to the lefthand incoming matrix attributes, except for special case operators.
Matrix adaptation flag (default = 0 if matrix arguments are present, otherwise 1) When the flag is set, the jit.matrix object will adapt to the incoming matrix planecount, type, and dimensions.
[in/out]_dim [32 ints]
The matrix data dimensions (default = 1 1)
The input or output name of the matrix (default = UID)
The number of planes in matrix input our output data. Except in special cases, this value is equal to the.
The input or output matrix data type. Except in special cases, this value is equal to.
The input or output matrix data type. Except in special cases, this value is equal to.
Output mode (default = 1 (calculate and output matrix))
0 = No output
1 = Calculate and output the matrix
2 = Pass input (no calculation)
3 = Pass output (no calculation)
The matrix data type (default =
Supported data types are , , , or .
Adapt output matrix dimensions to matrix input. If dimension arguments provided, default = 0, otherwise default = 1.
Set movie codec for recording (default = prores4444).
dstrect [4 ints]
The portion of the output matrix written to by the input frame (default = 0 0 (matrix width) (matrix height)).
The proportions of the rectangle are expressed in the form left top right bottom . All values are relative to the top left corner of the object's viewing area.
Video engine backend. This argument can only be set in the max box. If not specified, it is determined by the Video Engine Max preference. As of this writing, possible values include avf (Mac only), and qt .
Frames Per Second
Interpolation flag (default = 0)
When the flag is set, the incoming matrix is interpolated when scaling to display.
planemap [4 ints]
The plane mapping from input matrix to output movie (default = 0 1 2 3)
Preview flag (default = 0 (off))
Typically, the jit.vcr object passes input matrices directly to the outlet without any processing. Enabling preview during recording permits viewing of the compressed frames as they are recorded.
srcrect [4 ints]
The portion of the input matrix used when copying an input matrix to the internal matrix. (default = 0 0 (matrix width) (matrix height)) The proportions of the rectangle are expressed in the form left top right bottom . All values are relative to the top left corner of the viewing area of the input matrix.
The current duration, in QuickTime time units, of media written to disk (default = operation-specific)
The time attribute only returns data during operations.
Destination rect flag (default = 0)
When the flag is set, the dstrect attributes are used when copying an input matrix to the internal matrix.
Source rect flag (default = 0)
When the flag is set, the srcrect attributes are used when copying an input matrix to the internal matrix.
