I was frustrated with iMovies converstion of my beautiful time lapse pictures to a horrible, grainy movie format, and this app does a great job of simply transforming pictures into a movie. The quality is excellent - way better than iMovie, and a much more simple workflow. For my digital picture JPEGs, I recommend setting the app for the JPEG Codec and Max quality. Its also nice that the photos are resized to 1080p at the same time - makes the workflow quite simple! Thanks!
Now, if only I could add the movie file back into iMovie with this quality maintained!
