Why captions matter in short-form video
Plenty of people watch videos on public transport, at work or with their phone on mute. If the message lives only in the audio, that audience misses it. Captions make the video understandable without sound and also help people who are listening, especially with technical terms or names.
They're an accessibility matter too: deaf and hard-of-hearing viewers rely on them. They also help anyone watching in a second language. That's why large, readable captions have become a standard of the format on TikTok, Reels and Shorts.
How captions work in Vaideo
Vaideo writes the script, narrates it with an AI voice and adds captions in the same pass, so there's nothing to transcribe and no timings to adjust. They appear animated, synced to the voice, and are burned into the video: not a separate file a platform might hide.
There's a practical upshot: you don't need to switch on TikTok's or Instagram's auto-captions. If you do, you may end up with two overlapping layers of text. Nor do you have to leave space by hand: the video already comes built for the format you picked.
Since captions mirror the narration, the best way to improve them is to improve the text: short sentences and plain words can be read at a glance. If a name must be spelled a certain way, say so in the prompt.
What captions can't do on their own
Captioning doesn't make a video go viral: it helps the message land, but reach depends on the topic, the hook and each platform's algorithm. Nor do captions replace good structure: a strong first line, a single idea and a clear close.
If your audience speaks the other language, generate a separate version narrated in English or Spanish rather than relying on the platform's machine translation.

Tips that make the difference
- ★Short sentences: if a line can't be read at a glance, split it.
- ★Don't switch on TikTok's or Instagram's auto-captions on top of Vaideo's.
- ★Check names, brands and figures before posting.
- ★Keep platform text (stickers, titles) away from the caption area.
- ★Put the video's keywords in the description: burned-in text isn't always indexed.

Frequently asked questions
Can captions be turned off?+
No, they're burned into the video, which is exactly what makes them show on any platform or player.
Can I change the caption font or colour?+
Vaideo applies a predefined animated caption style. If you want it closer to your brand, you can adjust the caption style afterwards in Vaideo Editor (free).
Can I caption a video I already have?+
Not automatically: Vaideo creates new videos from a prompt or article URL, with captions included. In Vaideo Editor (free) you can upload your video and add text by hand, but it doesn't transcribe your audio.
What if a caption is misspelled?+
Captions follow the script. Write the term in the prompt exactly as it should appear and generate the video again.
What languages are captions in?+
In the narration language: English or Spanish. Captions aren't generated in a different language from the voice.
Do captions improve reach?+
They help the video make sense without sound and make it more accessible, but no feature guarantees more views.
