  Here's the script, by the way, can you send me yours?
https://github.com/kieranjol/ifi-ffv1
Here's what the console looks like when it's executing that part of my script.

+ framerate=($(ffprobe -v error -select_streams v:0 -show_entries
stream=avg_frame_rate -of default=noprint_wrappers=1:nokey=1 "$1"))

++ ffprobe -v error -select_streams v:0 -show_entries
stream=avg_frame_rate -of default=noprint_wrappers=1:nokey=1
'augtest/v210 space.mov'

+ IFS=:

+ read -a timecode

++ ffprobe -v error -show_entries stream_tags=timecode -of
default=noprint_wrappers=1:nokey=1 '/augtest/v210 space.mov'

+ printf -v timecode ''\''%s\:%s\:%s\:%s'\''' 01 00 00 00

+ echo ''\''01\:00\:00\:00'\'''

'01\:00\:00\:00'

+ drawtext_options=(fontsize=45 fontfile="/Library/Fonts/Arial
Black.ttf" fontcolor=white timecode="$timecode" rate="$framerate"
boxcolor=0x000000AA box=1 x=360-text_w/2 y=480)

++ IFS=:

++ echo 'fontsize=45:fontfile=/Library/Fonts/Arial
