In order to retrieve timecode information from a movie, you can send the message ‘gettimecodeinfo’ and ‘gettimecode’ to query the state of those attributes. The values come out of the right outlet as ‘timecodeinfo’ and ‘timecode’ messages.
‘timecode’ and ‘timecodeinfo’ are gettable attributes (but are not settable).
Whenever a movie is read into jit.qt.movie, it sends out a read message that reports whether the movie was read in successfully. You can use that information to trigger a getmoviedim message to jit.qt.movie, and use the moviedim to set the dim of jit.qt.movie and all other objects that need to know that information.
A jit.movie or jit.qt.movie object doesn't automatically provide a notification when it reaches the end of a video. However, it's easy enough to obtain such a notification by checking to see when the video's current time becomes equal to its total duration.
You can easily jump to different parts of the movie using the readymade object called playbar.
For this example to work properly, you will also need to download the small text file subtitles.txt.
To jump immediately to a new location in a movie, you can send the frame message to jit.movie (or jit.qt.movie). To crossfade to a new location, instead of a jump cut, you need to be playing the video twice, and crossfade from the current video to the second video, after which you can stop playing the first video. To do that again, you can just reverse the process: start the first video at the new location, crossfade back to the first video, and stop playing the second one.
You can make a crossfade between two videos or betwen two sounds by multiplying the amplitude of one of them by values going progressively from 1 to 0 while you multiply the other by values going progressively from 0 to 1. In this example, we use a slider object that outputs values from 0 to 1 to control the volume of two movie soundtracks, using the vol attribute of jit.qt.movie (or jit.movie).
You can use the gettime message to ask jit.qt.movie for a report of its video's current time location (in QuickTime time units). The report comes out of the right outlet of jit.qt.movie as the word time followed by the current time.
