e-prime - student version?

[Kim, Kisok]

Is there a plan for the "student version" of the e-prime?  -- lower priced one with limited function?

	Although movie playing is the top feature for E-Prime
	2.0 later this year, E-Prime 1.x does not support
	playing videos during critical timing trials (it can
	play instruction movies through power point).
	
	Since you mentioned your movies are 1000ms, at a rate
	of 30 frames a second, you would have aprx 30-40
	images per movie.  If you are capable/willing to split
	each frame up into its own .bmp file, you can display
	them in E-Prime one after another to create an
	animation.
	
	Specifically, there is a sample on the PST Web Support
	site called "sprite manager" that could be used for a
	paradigm similar to what you have described,
	especially if the movies you wish to present are not
	full screen since Sprite Manager helps allocate video
	resources beneficially versus brute force canvas
	object creation.  The info/help document that
	SpriteManager installs off the Start/E-Prime menu is
	very valid reading for any paradigm that involves
	images.  Using SpriteManager coupled with small framed
	text display objects and appropriate InLine script,
	your paradigm could potentially be implemented.
	
	Using Sprite Manager or brute force canvas objects in
	E-Prime will permit for your paradigm to have the
	critical timing you would need.
