I have imported a PNG (I require high quality and transparency) into Flash MX 2004.
I have a symbol that has two symbol levels to it:
In "Symbol1" I have 5 pictures in 5 consecutive keyframes.
In "Symbol2" I have "Symbol1" fading in and out.
On the main timeline when a button is clicked "Symbol2" plays making the picture fade out, switch to a new picture then fade back in and STOP.
On the main timeline everything is within the first keyframe. The pictures look great and everything works fine. BUT when I extend ANY layer on the timeline past the first keyframe my pictures become pixelated. It doesn't matter what layer is extended. As long as no layer extends past the first keyframe the pictures look fine. Otherwise they are horribly pixelated.
There seems to be no mechanical problem answer here. I have changed the Bitmap properties of the main pictures with no effect.
