- scans one flat input directory
- auto-detects media/audio/data files by extension
- shows each image fully visible for 6 seconds by default, not counting crossfades
- keeps the first image longer so the first transition starts at 12 seconds by default
- keeps the first image longer so the first transition starts after 2x image duration, 12 seconds by default
- includes video clips inline
- crossfades between media items over 3 seconds by default
- loops/trims music to match the video
