How to create an image slideshow with images from different devices and of different formats, both image and landscape, using ffmpeg, exiftool and imagemagick

video.md

1. Use exiftool to sort according to exif data (apt-get install exiftool)

exiftool "-FileName<DateTimeOriginal" -d "sorted/%Y%m%d_%H%M%S.%%e" .

2. Rotate and resize

mogrify * -auto-orient -resize 1920x1080

3. Pad images

mogrify * -gravity center -background black -extent 1920x1080

4. Encode

ffmpeg -framerate 1/5 pattern_type glob -i "*.jpg" -pix_fmt yuv420p output.mp4

5. Add Sound

ffmpeg -i output.mp4 -i track.wav -c:v copy -c:a aac -b:192k video.mp4

Done! I hope this saves someone some time cause I lost some of mine on this.
