I have created a project using motion and sound. I need to add a skin to it which you use to be able to do when you published it. Now it seems the only way to do it is by exporting my file into Media encoder then convert it to a MP4 ( there is no F4V or FLV in Media encoder, that I can see). When I export this my sound quality is lost. Then when I re-import into Flash to add the skin I lose the sound all together. What am I doing wrong?
