Play a QuickTime movie
Use the jit.movie for working with QuickTime movies.
This document refers to the avf engine version of jit.movie.
The avf backed jit.movie is asynchronous when seeking (e.g. setting the time attribute or using the or messages). This means that the frame output immediately following a seek request is not guaranteed to be correct. Users requiring exact frame timing must use the message output from the object's dump outlet to trigger frame output.
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.

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), qt and viddll .
Internal FPS for the movie
Number of frames in the movie
Frame reporting flag (default = 0). When enabled, the message jit.movie object as each frame is processed, followed by the number of milliseconds spent doing so.will be sent from the rightmost outlet of the
Output interpolation flag
Looping mode (default = 1 (start to end))

The movie loop point end. Time is specified as QuickTime time values.
looppoints [2 ints]
The movie loop points. Time is specified as QuickTime time values.
Loop notification flag (default = 0). When enabled, the jit.movie object will send the message when the playing movie passes the loop point. In palindrome looping mode, the message will be sent at both the beginning and the end of the movie.

Enable OpenGL texture output (default = 0). When enabled an OpenGL texture is output instead of a Jitter matrix. The object's drawto attribute must be set to a valid gl context. An RGBA texture is output using the movie's native dimensions. When enabled, the following attributes have no effect:
