Getting the height and width of a videoclip

[William Ziegler]

I have a stack that allows teachers and parents to attach videos for  
students to write sentences about. These videos are created with  
various devices and thus have different heights and widths.  I  
currently store these videos in a default folder, and use a 'Player',  
which I probe for the Height and Width to resize large clips to a set  
maximum size.

Teachers have asked if I could package all the videos into each stack  
to make it easier to send home and/or share lessons with other teachers.

I am having a hard time manipulating videoclips with the PLAY command  
as compared to using a 'Player' with external video files.

Player example:

create player "myPlayer"
Set the filename of player "myPlayer" to fName
put the width of  player "myPlayer" into realWidth
put the height of player "myPlayer" into realHeight
if the height of player "myPlayer" > 330 then
put 330/realHeight into theRatio
set the height of player "myPlayer" to theRatio *RealHeight
etc.

I know I can set the RATIO of stack based videoclips, but how can I  
find their initial size in order to know if their image will be too  
large?

Is my best option to store the clips in the stack, temporarily export  
them to the hard drive when needed,use the file in a 'Player', then  
delete the file when finished.
