Very easy. You have a lot of pictures on an SD Card from a time-lapse. They are all in folders of a 1000, and now you want to import that beast to Final Cut (FCPX).
I show the fastest method with command line ffmpeg.
ffmpeg -f image2 -pattern_type glob -i '/Path to your folder/DCIM/**/*.JPG' -r 30 -vcodec prores /your destination folder/timelapse.mov
Have fun, and show some love with likes and comments!
