I found a tutorial:
Importing MOV Files Into Flash
Introduction
The object of this tutorial is to demonstrate how Quicktime MOV files can
be used in flash movies. There seems to be some confusion about this but
let me start by saying that the flash player cannot actually play any type
of digital video. This confusion is fueled by the ability of flash to
import MOV files and to export it's movies in MOV or AVI format.
However, there is a method by which digital video can be simulated in
flash and give an acceptable result.
Import the MOV
The first step is to import the MOV you wish to use into the flash stage.
For this step, forget about where you eventually want to use the MOV and
just open a new movie on the flash stage. Click the first keyframe and use
File->Import to bring the MOV into flash.
You will see just the first frame of the MOV on the stage. This is normal.
At this point, I would size the flash movie to the same dimensions as the
MOV image on the stage. This is not required, but if you do not do this,
you will have a border around your movie at a later stage.
To import the rest of the MOV frames into flash, you must now expand your
movie to the same number of frames as contained in the MOV file. Do this
using either the F5 key or the Insert->Frame menu. Add enough frames for
the full length of your MOV.
What? You don't know how many frames are in your MOV? Well, just keep
clicking till you think you have enough. You can click the mouse on a
frame in the time-line, which will now display the corresponding frame
from the MOV, to check your progress. When you run out of frames in the
MOV, flash will begin to display an "X" in a box to show an empty frame.
These empty frames should be deleted unless you wish to add empty space to
the end of the movie for titles or some other purpose.
You should now have your entire MOV imported into flash, frame-by-frame,
and you may now go back to frame 1 of the time-line and view the results
by either pressing Enter or using the ">" Key to advance through the
frames.
However, flash is still linked to the MOV file and is using that link to
display the images. The images are not really imported into your movie at
this point.
Export the MOV Frames
The next step is to export the linked MOV frames to a file format. Select
File->Export Movie opening the export dialog box. Beneath the file name
entry box is a drop-down list labeled "Save as type:." Use this drop-down
to select the file type "Bitmap Sequence (*.bmp)." Just a note on
organization here. I usually create a new folder for these exported files.
These files will all be deleted at a later stage and this makes it much
cleaner and simpler to do this.
Flash will now export each frame of your movie, appending a sequence
number to the file name that you have given it.
Once your movie has been successfully exported as a bitmap sequence you
may delete the flash movie on the stage.
Import the Bitmaps
Now you need to bring the bitmaps back into flash. At this point, you can
use another new movie (that can later be converted into a movie clip) or
insert it directly into your final product. In the demo fla attached to
this tute, I have inserted it directly into the finished movie for
simplicity.
Highlight the first key frame where you want the bitmap sequence to be
inserted. Now select File->Import and set "Files of type:" to "All Files
(*.*)." You will notice that flash has appended a number to each file you
exported earlier, assigning "0001" to the first file. Click on this file
to import.
When you do this, flash recognizes that this is the first of a sequence
and opens a dialog that says "This file appears to be part of a sequence
of images. Do you want to import all of the images in the sequence." Say
"Yes" to this dialog.
Flash now imports the sequence of bitmaps into individual frames in your
movie. That's really all there is to it. Play the movie back, and there's
your MOV (more or less) embedded into your flash presentation.
Loose Ends
You are now finished with the bitmap sequence files and they may be safely
deleted from your work folder.
You may have also noticed that I have been silent on the subject of sound.
This is one minor hang-up of this system. Flash cannot separate the sound
track from the MOV file into a separate WAV file, which is what you need
to import the sound.
To get the sound track you will need to use Quicktime "PRO" or some other
sound editing application that has the capability of making a WAV file
from the MOV soundtrack. You then import the sound track like any other
sound loop. Synchronizing and so forth is up to you. It can be done
reasonably well however with a little experimenting with frame speeds,
etc.
I was prompted to write this because I seemed to be outlining this on the
message board about once a week so there seemed to be a need for some
comments on the subject. I hope you have found this tute useful.
