What is the difference between subtitles and captions?

Subtitles vs Captions

Subtitles

Subtitles do not have any sound indications.

They are the transcribed or translated dialogues.

Captions

Captions are subtitles for the Deaf and Hard of Hearing people.

Captions contain sound indications.

We also use the term : Open Captions and Closed Captions.

Two kind of captions

Closed Captions

Closed captions are user-enabled captions.

According to the plateforms, users can choose :

font
font size
color of captions
add background with color on captions.

Open Captions

Captions are embedded in the video. Everyone sees the captions.

The users have no choice as to the display and the format of the captions.

So, let's talk about open captions.

Demonstrations

Meryl Evans

"Without further ado ... I've created a brand new side-by-side video. One uses captioning best practices (except it's open instead of closed) and the other uses different types of Hormozi-style options. Which do you prefer?"
