How to add captions to YouTube Shorts: automatic, typed and burned in
Captions decide whether a Short works with the sound off, and many people watch that way. There are three ways to add them, each with a different job. Here is how to do each one, and which to pick.

To add captions to YouTube Shorts, you have three options: let YouTube make automatic captions, add your own captions in YouTube Studio (typed, synced or uploaded as a file), or burn captions into the video itself before you upload. The first two are closed captions that viewers can switch on and off. The third is always visible, which is why most faceless Shorts use it.
Most strong Shorts use burned in captions for the viewer and keep accurate closed captions as well.
Why captions matter on Shorts
Two reasons, one practical and one human.
People scroll with the sound off. In a quiet office, on a bus or late at night, a Short without visible words is just moving pictures. If the hook is not readable, the viewer swipes. YouTube's Shorts guide tells creators to "Capture attention in the first few seconds to prevent viewers from scrolling," and on mute that only works with text on screen.
Many viewers need them. The World Health Organization says over 5% of the world's population, or 430 million people, need rehabilitation for disabling hearing loss. Captions make your video watchable for them too.
Method 1: automatic captions
YouTube creates captions on its own using speech recognition. Its automatic captioning page has a section on "Automatic captions on long-form videos and Shorts" and lists 67 supported languages.
You do not have to switch anything on. But automatic captions have limits:
- They are closed captions, so viewers only see them if they turn captions on.
- YouTube warns they "might misrepresent the spoken content due to mispronunciations, accents, dialects, or background noise."
- They may not be made at all if the language is not supported, the sound is poor, there is a long silence at the start, or several people talk at once.
How to check and fix them: in YouTube Studio, open Subtitles in the left menu, pick the Short, then select More next to the automatic track to review and edit any lines that came out wrong. Names, numbers and niche words are the usual mistakes.
Method 2: add your own captions in YouTube Studio
YouTube's subtitles help page describes three ways once you open Subtitles, pick your Short, select Add language and then Add under Subtitles:
- Upload file. Choose "With timing" if you have a caption file such as an SRT, or "Without timing" for plain text, then select the file and save.
- Auto-sync. Paste the words spoken in the Short (your script is perfect for this) and YouTube times them for you. This is the fastest accurate method for faceless videos, because you already have the script.
- Type manually. Play the Short and type as it plays. YouTube sets the timing. You can add sound notes like [door creaks].
Auto-sync is the one to remember. You wrote the script, so you have exact captions for free.
Method 3: burned in captions
Burned in captions (also called open captions or hardcoded subtitles) are part of the picture. You add them in your editor or video tool before you export. They are what you see on almost every faceless Short: big words that pop on screen in time with the voice.
They have real advantages:
- Always visible, even if the viewer never touches the captions button.
- Full control of style: size, font, color, position and how many words show at once.
- Part of the look. A consistent caption style helps viewers recognize your channel.
And one drawback: you cannot fix a typo after upload without exporting a new video. Proofread before you export.
How to style burned in captions
A few rules that hold across niches:
| Choice | Recommended | Why |
|---|---|---|
| Words on screen | One to three at a time | Easy to read at a glance |
| Size | Large, heavy font | Readable on a small phone |
| Position | Middle of the frame, above the bottom third | The app's caption and buttons cover the bottom |
| Contrast | White text with a dark outline or shadow | Readable on any background |
| Timing | Matched to the voice word by word | Feels like the narrator is speaking |
Keep the hook as its own large line in the first second. Our guide to YouTube Shorts size explains the safe zone where the app draws over your video.
Which method should you use?
| Method | Viewer sees it by default | Effort | Best for |
|---|---|---|---|
| Automatic captions | No | None | A backup on every Short |
| Your own captions in Studio | No | Low with auto-sync | Accuracy and accessibility |
| Burned in captions | Yes | Done in your editor | Keeping viewers on mute |
For a faceless channel, the usual answer is burned in captions for every Short, plus auto-synced captions from your script when you have a minute. If you write your scripts first, as our guide on how to write a YouTube Shorts script suggests, you already have the text.
Captions on TikTok and Reels
The same file works on the other apps, and they have their own caption tools. On TikTok, auto captions are chosen on the editing page after you upload or record, creators can edit the text once it is made, and viewers can switch them off from the share panel. Burned in captions sidestep all of that and look the same everywhere. If you post one video to several apps, see cross posting TikTok videos to YouTube Shorts.
Common caption mistakes
- Captions behind the buttons. Text in the bottom third or the far right is covered by the app.
- Whole sentences on screen. Viewers cannot read and watch at once. Break lines into short chunks.
- Captions that do not match the voice. If the voice says one thing and the text another, viewers notice.
- Thin fonts with no outline. They disappear on bright scenes.
- Never checking automatic captions. A misheard name in your own captions looks careless.
How FacelessHype adds captions
Every FacelessHype video comes with captions burned in, big and heavy, timed to the voice. You choose one word at a time, two words, or the full line, and the captions sit just above the bottom third of the frame, clear of the caption and buttons the apps draw on top. You see a preview of every scene before anything is made, so you can fix a line before it ever appears on screen. Try it with the motivation or fun facts format, read how text to video AI times the captions to the voice, or start from the YouTube Shorts maker.
Quick answers
Does YouTube add captions to Shorts automatically? Yes, in supported languages, as closed captions viewers can turn on. Check them in YouTube Studio under Subtitles.
Can I add subtitles to a Short after uploading? Yes. Closed captions can be added or edited in YouTube Studio at any time. Burned in captions need a new export.
Should I use burned in captions or closed captions? Both if you can. Burned in captions keep viewers on mute, and closed captions help accessibility.
What caption size works on Shorts? Large and bold, one to three words at a time, in the middle of the frame.
