Better to import FLV or SWF? Feb 10, 2014 By Steve McAneney Hi there everyone. I am importing some animations which a supplier is preparing for me. There will be no interaction, just viewable movies. My question is this; should I ask the supplier to provide me with swf, or flv files to import into Storyline? For some reason I am under the impression it would be better to insert flv files into Storyline, and let Storyline compile them into swfs. Is this correct? If so, why? Thanks a lot.
