+- overlays the opening title for the first 6 seconds: large bold title, then smaller non-bold date/location on one line
+- adds persistent bottom-left title/date/place and bottom-right `marijo@novosel.dk` stamps
+- writes an MP4 file named like `YYYYMMDD_title.mp4` by default
+- takes `YYYYMMDD` from the first picture/video metadata, falling back to file modification date
+- uses local `ffmpeg/ffmpeg` and `ffmpeg/ffprobe` when present, otherwise system tools
