VideoFrame
tag in a SWF file. VideoFrame provides a single frame of video data for a video character that is already defined with DefineVideoStream.
In playback, the time sequencing of video frames depends on the SWF frame rate only. When SWF playback reaches a particular SWF frame, the video images from any VideoFrame tags in that SWF frame are rendered. Any timing mechanisms built into the video payload are ignored.
A VideoFrame tag is not needed for every video character in every frame number specified. A VideoFrame tag merely sets video data associated with a particular frame number; it does not automatically display a video frame. To display a video frame, specify the frame number as the Ratio field in PlaceObject2 or PlaceObject3.
