## Error

```text
Error opening input file Screen Recording 2026-09-30 at 4.57.33 AM.mov.
Error opening input files: No such file or directory
```

## 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.

## Fix
Glob the name instead of typing it, or match the character explicitly:
```bash
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).

## Verify
Using the glob, ffmpeg opened both recordings and extracted the audio.
