NOTE #1: There is Quality Control menu at the bottom of the Movie for lowering the quality if you encounter problems with the movie.
NOTE #2: I have optimized the video as well as set the default quality to Medium to see if the Audio Cut-off and lag would stop. Sorry for the inconveniences. Please, if it continues to cause problems, do let us know, we'll do what we can to fix it. Thanks for Watching! :)
