Movies
KEY
TYPE
VALUE
Rotate
integer
boolean or stream
(Optional)
The number of degrees by which the movie is rotated clockwise
relative to the page. The value must be a multiple of 90. Default value: 0.
(Optional)
A flag or stream specifying whether and how to display a
poster
image
representing the movie. If this value is a stream, it contains an image
XObject (see Section 4.8, “Images”) to be displayed as the poster. If it is the
boolean value
true
, the poster image should be retrieved from the movie file;
if it is
false
, no poster should be displayed. See implementation note 152 in
false
.

KEY
TYPE
VALUE
Start
(various)
(Optional)
The starting time of the movie segment to be played. Movie time
values are expressed in units of time based on a
time scale,
which defines the
number of units per second. The default time scale is defined in the movie
data. The starting time is nominally a non-negative 64-bit integer, specified
as follows:
•
If it is representable as an integer (subject to the implementation limit for
integers, as described in Appendix C), it should be specified as such.
•
If it is not representable as an integer, it should be specified as an 8-byte
string representing a 64-bit twos-complement integer, most significant
byte first.
•
If it is expressed in a time scale different from that of the movie itself, it is
represented as an array of two values: an integer or byte string denoting the
starting time, as above, followed by an integer specifying the time scale in
units per second.
If this entry is omitted, the movie is played from the beginning.
Duration
(various)
number
(Optional)
The duration of the movie segment to be played, specified in the
same form as
Start
. If this entry is omitted, the movie is played to the end.
(Optional)
The initial speed at which to play the movie. If the value of this en-
try is negative, the movie is played backward with respect to
Start
and
Duration
. Default value: 1.0.
(Optional)
The initial sound volume at which to play the movie, in the range
−1.0
to 1.0. Higher values denote greater volume; negative values mute the
sound. Default value: 1.0.
