Video rename (with Deno) and convertion from h.265 to h.264 (with ffmpeg)

How I move files from iPhone to Google Drive

  • Copy files to computer using 3uTools.
  • Rename files with for c in save-renames rename; do deno run -A --unstable rename.ts $c; done.
  • Remove .webp files because they are trash.
  • Move video files in ./video directory (.mp4, .mov).
  • Create ./video_x264 and run ./convert.sh.
  • Wait for million years.
  • Check ./video_x264 and remove ./video.
  • Review media collection with Filter UI.
