Optimizing before publishing

[maxos]

I got a presentation which consists of 18 screens. Each is done like that there is a Quicktime video in the background and shapes or bitmaps with their behaviours on it. But when I publish it, it is not moving so smooth - I mean for example: appearing of the buttons which are actually on the movie which is their background is sometimes instead of a nice fade, just slideshow. ...any idea how to make it better?

Maybe, will it make any change, when I replace .psd files on the scene with gifs or jpegs? I mean does smaller size of files affect whole working of a projector (speed)? I know that flash objects can be buffered into memory sonner than viewed but how is it here with bitmaps...?

ManyMany thanks.
Any help would be appreciated

Placing a button on top of a video - this requires a lot of processor power. Can it be a series of images instead of the video?

no, it really can not. It s about 1:30 min long video. However, I also had such answer: "One basic thing, oversized graphics should be prescaled, perhaps with
ransfom bitmap command, rather than sizing print resolution image on
stage.

File size does not always reflect the ram overhead of an image, once a
jpeg is loaded into memory it's ram requirement is the same as other
images, the bytes requires is W x H x depth / 8.

If you are not using the alpha channel of psd files they could be
reduced in depth, 16 bit bimaps have a lower ram overhead.

Transitions can vanish if a very low ram condition comes up, Mac OSX
projectors lose non linear navigation tansition effects in some director
vesions ( if the transition is at a frame accessed by go to frame
instead of by simple score frame advance )

The biggest problem, If that's a real quicktime video in the backgound
you mentioned is the added stage compositing overhead of including the
video frames at the video play frame rates. Using video for backgrounds
where the direct to stage property must be turned off will always cause
a large loss in animation speed. An aside, quicktime does support a
fixed 1 bit mask that may be assigned by lingo, allowing sprites in
lower channels to show through a direct to stage quicktime sprite, some
of the fixed superimposed sprites could be merged into the in advance
video inside of the video editor. White active sprites with fixed
positions and outlines could be shown through holes in the video defined
by the mask."

---do you agree? Coz I am not so smart from it )

Masking the background movie is actually a good idea, as you can set the video's DTS (Direct To Stage) turned on. DTS video plays much faster than non-DTS video.

If it's too much of a hustle, things you can try are to change the video codec, and change the graphic to PNG with copy ink.
