Many people confuse captions and subtitles. Do you feel the same?

Although many people often use subtitles and captions interchangeably, they have different definitions.

Understand the difference between subtitles and captions, you’ll know how to choose the one that best fits your video making purpose.


Captions are used to increase access to videos for the deaf or people having hearing problems.

Captions are often presented in phonetic form, they are usually word by word, and they may not match the conversation tempo, or the actions of the actor.

Captions can also include ambient noises, speaker differences, and important audio information that helps viewers understand the video content even though they can’t hear it.

Captions usually appear as white text on a black bar, and appear mainly in the bottom corner of the screen.

Videos using open captions are permanently embedded in the videos. However, subtitlers commonly use closed captions, allowing viewers to turn them on or off.


Subtitles are translations of a video transcription, which help viewers understand what is happening on screen, what the actor is saying in the video.

Subtitles usually appear as text at the bottom of the screen. Subtitles support viewers who are non-native speakers, but can normally listen to other sounds such as music in videos, voices of actors talking, etc.

Subtitles used for the deaf or people having hearing problems include non-dialogue information such as speech recognition, or sound effects recognition.

If viewers can’t hear the video sound, subtitles additional information will assist them in understanding video content.

Create different subtitles for different audiences

Both captions and subtitles provide valuable information that enhances the viewing experience.

To create optimal experience, subtitles need a certain quality.

One basic rule is subtitles should be responsive, provide all important information without distracting viewers, or causing inaccuracy.

A good subtitler needs to know how to control subtitles optimal speed to adjust subtitles matching the video speed and tone.

This person can choose a suitable video frame to start and end the subtitles.

What if the subtitler doesn’t pay attention to these details, how terrible those mistakes will degrade video quality.

Slow or too fast subtitles can ruin the video as well. Imagine you are watching a movie having subtitles slower or faster than the actors’ speech. It’s very annoying, right?

In addition, subtitlers also need to calculate the number of on-screen speakers. So they can change the subtitle type, or subtitle tempo based on how fast and slow the scenes or speakers appear (one, two or many speakers).

The slow or quiet scenes also require changing subtitle timing, allowing subtitles to appear longer on screen.

With fast-paced videos, or videos having multiple speakers at the same time, it’s a challenge for subtitlers to ensure each character’s subtitles appear on the screen in time.

However, an experienced subtitler will have skills to remember these elements, and know how to optimize video quality by speeding up subtitles.

Refer to some experiences below to create high-quality videos:

  • Every video second contains about 24 frames, a good subtitler will know what is the best frame to insert subtitles.
  • The subtitles timing tells us when the text appears and disappears on the screen. So, subtitles need a right pace to keep up with actors’ actions.
  • Sometimes, the subtitle maker needs to shorten the subtitles down without losing the meaning of speeches spoken in the video.
  • That means the subtitler needs to choose the exact replacement so as not to make the dialogue deviated from its true meaning.
  • Each second in a video should contain between 12 and 15 characters.

Besides time, subtitle text and format are also important, some features to keep in mind include:

  • Use an easy-to-read sans-serif font with a consistent width and a thick border.
  • Use additional symbols for information (for example, a musical note).
  • Subtitles must match the spoken words style; for example, when the actor uses slangs or specialized words, the subtitler must find another alternative, or a shortened word conveying equivalent meaning.
  • The subtitles should be 2 lines long, containing about 35 characters.

Subtitles work differently for different audiences

When creating subtitles, in addition to the content, you also need to pay attention to the video’s audience.

Subtitles may have changes to suit each audience. For example, the subtitles used in films for children will differ from those used in adult films.

Moreover, the subtitles used in films, dramas, movies aiming to expertize audiences might be quite different from those used in movies, films, dramas for ordinary people.

Before creating subtitles, subtitlers should define which audience the films or movies he is doing sub will serve.

The better a subtitler understands the video purpose, the more accurate, clearer, and better quality the subtitles will be.
