Video Slider Change Color

[Five]

I would like to have a video slider that changes color. What I mean, is
that I want the slider to slide along for instance a white rectangle. Once
the video slider has played an area, I want that part of it to turn red.

If that is unclear, here is a quick pic of what I have in mind:

I just wanted to know if this was possible to do in director.

Thanks,

One approach would be to overlay a 'tinter' sprite, perhaps with
'darkest' ink over the slider base. The set the width of the overlay
sprite proportioned to the video sprite currenttime / video sprite's
member duration, check the lingo terms used for your media.

I am not familiar with this at all, but I'll give it a try. I am attempting
to use avi (which doesn't have a built in slider). Learning as I go, I
guess.

The easiest approach would probably to adapt the library
window/media/quicktime slider. It does, I think a moving handle rather
than a growing box

I don't AVI much but that behavior may well work with AVIs too.

Again the keyAVI properties used to drive a slider are the duration of
member videoMemberr and the movieTime of sprite videoSprite

for video on channel 10


on exitFrame


playFraction = sprite(10).movieTime / float(sprite(10).member.duration)

--With the progress rect on channel 12 and the slider range rect on 11.
-- ( width works when the regpoint is on the left of the sprite)

sprite(12).width = sprite(11).width * playFraction

end
