в хелпе есть такой пример прелоадера видео:

Example
The following example creates a progress bar using the Drawing API and the bytesLoaded and bytesTotal properties that displays the loading progress of video1.flv into the video object instance called my_video. A text field called loaded_txt is dynamically created to display information about the loading progress as well. 

var connection_nc:NetConnection = new NetConnection();
connection_nc.connect(null);
var stream_ns:NetStream = new NetStream(connection_nc);
my_video.attachVideo(stream_ns);
stream_ns.play("video1.flv");

this.createTextField("loaded_txt", this.getNextHighestDepth(), 10, 10, 160, 22);
this.createEmptyMovieClip("progressBar_mc", this.getNextHighestDepth());
progressBar_mc.createEmptyMovieClip("bar_mc", progressBar_mc.getNextHighestDepth());
with (progressBar_mc.bar_mc) {
    beginFill(0xFF0000);
    moveTo(0, 0);
    lineTo(100, 0);
    lineTo(100, 10);
    lineTo(0, 10);
    lineTo(0, 0);
    endFill();
    _xscale = 0;
}
progressBar_mc.createEmptyMovieClip("stroke_mc", progressBar_mc.getNextHighestDepth());
with (progressBar_mc.stroke_mc) {
    lineStyle(0, 0x000000);
    moveTo(0, 0);
    lineTo(100, 0);
    lineTo(100, 10);
    lineTo(0, 10);
    lineTo(0, 0);
}

var loaded_interval:Number = setInterval(checkBytesLoaded, 500, stream_ns);
function checkBytesLoaded(my_ns:NetStream) {
    var pctLoaded:Number = Math.round(my_ns.bytesLoaded/my_ns.bytesTotal*100);
    loaded_txt.text = Math.round(my_ns.bytesLoaded/1000)+" of "+Math.round(my_ns.bytesTotal/1000)+" KB loaded ("+pctLoaded+"%)";
    progressBar_mc.bar_mc._xscale = pctLoaded;
    if (pctLoaded>=100) {
    clearInterval(loaded_interval);
    }
}
