Showing Milliseconds in Celluloid/mpv

Needed a way to show milliseconds when playing a video for accurate timestamps. Found a way with mpv (I used Celluloid) that was just a little out of date and got it to work.

In Celluloid go to Preferences -> Miscellaneous Tab and add the following to "Extra mpv options:"

osd-msg3=${=time-pos}

Place at the end of anything that may already be in the field.

Press and hold o (the letter) to see the milliseconds while a video is playing:

Enjoy.
