Hi I am stumped about creating top quality audio slideshows in iMovie. #1 What are the best dimensions/dpi for stills imported into iMovie for use in a slideshow that will be 16:9 (960x540 or 1280x720) and embeded on YouTube, Viemo etc. I can't seem to find the perfect answer anywhere. #2 Once we create the slideshow and want to export/share, what are the video and audio optimal settings in "export using quicktime" ? There are so many options. What is best for slides with spoken word audio underneath? We want quality but thought it wouldn't have to be as large since there is no video. Too often I feel like images look worse, pixelate, etc after the export. Thanks in advance.

Cool. So if we want an exported video to be 960x540 the images should be at least that big? And any thoughts on best practices for quicktime export settings with a slideshow? i thought some would be unique since there are no movie/video clips. thanks
