Hi,

Is there some available documentation on MovieDisplay objects (getting/setting properties, e.g.)? I've looked in a few places but haven't found it, so I apologize if I've missed it.

At the moment, I'm wondering whether the FrameRate that's reported in the log is somehow adjustable. The frame rate that's reported (33.3 or so) is not what I expect from the Cinepak-encoded QuickTime movie I'm displaying (set to either 29.97 or 30.00), and the log doesn't report any dropped frames. Any ideas for me?

Thanks,

Shane Kippenhan

The current public release of the EP2 BETA (2.0.1.61) is not the final implementation of how the Movie objects will display nor report their characteristics.  The current implementation reports back the frame time in how quickly the frames are being rendered into video memory and not displayed to the screen.

The next public release of EP2 BETA is scheduled to introduce the formal movie playback model in EP2.  Besides 0/1 ms delay to first frame, this model will also provide a collection of MovieDisplayFrame objects that will have properties for every frame in the movie including its status (rendered, scheduled, displayed, dropped), the timestamp as to when each of the operations occur.

Keep posted to the http://www.pstnet.com/e-prime/support/kb.asp?TopicID=2720 KB topic as its content will expand significantly in the upcoming days.  Industrial Partners are scheduled to receive the next line of build soon, with a public release a week or two thereafter.

Please see the attached .zip that expands to an .HTML file that was generated by enumerating a SlideMovie.Frames collection and reporting back some of the information avaialable.
