macOS Screen Recording/Screenshot filenames: "No such file or directory" because of a hidden U+202F before AM/PM
Error opening input file Screen Recording 2026-09-30 at 4.57.33 AM.mov. Error opening input files: No such file or directory
Glob the name instead of typing it, or match the character explicitly:
M=$(ls ~/Desktop/Screen\ Recording\ 2026-09-30\ at\ 4.57.33*.mov)
ffmpeg -nostdin -i "$M" -vn -ac 1 -ar 16000 out.wav
# or: f=$'Screen Recording 2026-09-30 at 4.57.33\u202fAM.mov'
Confirm with ls | grep 'Recording' | xxd | grep -i 'e2 80 af' (UTF-8 bytes of U+202F).
Symptom
ffmpeg -i "Screen Recording 2026-09-30 at 4.57.33 AM.mov" ... (typed or copied from Finder/ls output) fails with Error opening input: No such file or directory, although ls shows the file.
Cause
Recent macOS versions put a NARROW NO-BREAK SPACE (U+202F) between the time and AM/PM in screenshot and screen-recording filenames. It renders like a normal space, so a typed path with an ASCII space does not match.
Verify
Using the glob, ffmpeg opened both recordings and extracted the audio.
