I'm experiencing audio problems when playing two scenes at once. I was told that it's becuase my scenes have too many clips and that when the performance exceeds 100% the audio will stop to avoid being out of sync. Does anybody have suggestions as to how to make scenes "lighter?" What is the best thing ...

I'm trying to pull in social media files using Spredfast (vine, instagram videos, etc.) but all of the files seem to be in the .mp4 format. Does anybody know if there is a setting or plugin that allows .mp4 files to be played in Xpression? Or is that a feature that may be added in the future?
