Quick guide to Director Digital Video Commands

Note: in the member information inspector you can set these properties
loop, paused at start, crop/scale
Direct to State (DTS) - for sake of speed director can bypass all the sprites and put video straight on stage, but then all the sprite manipulation features will not work - uncheck dts

Speed - stop - go
speed ( 1 = forward  0= stop  -1= backwards 2= double speed etc)
sprite(2).movierate = 1

Location in the video
(measured in ticks - 60th/s of second)
sprite(2).movietime = 200

Total duration  (note it is for member not sprite)
d = member("movie1").duration

Volume of sound    (0-255 )
sprite(2).volume = 120

General sprite qualties
Transparency  (0 to 100%)
sprite(2).blend = 70

size 
(scale must be chosen in member inspector - not crop)
(uses directors rectangle feature)
for example rect (20,30,220,330) 
20,30 are coordinates of upper left corner
220,330 are coordinates of lower right corner
sprite(2).rect = rect (20,20,260,200) 
sprite(2).rect = rect(20,20,340,260)

loop (true or false)
member("movie1").loop = true
loop range  (play between movietime 200 and 400)
 sprite(2).loopBounds = [200,400]

================ quick examples to show how to use===
convert mouse motion to speed 
(assmume whole screen of 640 pixels width - 
put this as routine on movie script level)
call it via frame script for every frame

on exitFrame
  mousemoviespeed
end

assume we want to  convert the mouse postion into speeds from 0 to 5
on mousemoviespeed
  x = the mouseH
  -- real mouselocation ranges from 0 to 640
  -- but we want to get scaled speed not higher than 5
  -- if we divide the mouseloc by 120 that will get close
  -- for example at outer range 640/120 = 5.2 approx
  newx = x/120 
  sprite(2).movierate = newx 
end 

The routine could get + and - values by subtracting the middle cooridnate
  newx = (x - 320)/120

thus  if it were at position 320 it would get 0 (320-320)/120
      if it wre at postion 200 it would get -1  (200-320)/120 = -120/120
