If you’re creating YouTube Shorts, you’ve probably noticed that every viral video these days has eye-catching captions. Whether it’s bold, animated subtitles or dynamic fonts, captions have become essential for grabbing viewers’ attention. But why are captions so important, and how can you add them to your Shorts easily? Let’s dive in.
What Are Auto Captions for YouTube Shorts?
YouTube offers an auto-captioning feature, but it’s not perfect. While it’s free and built-in, here are some limitations:
- Accuracy Issues: Auto captions often misinterpret speech, especially if there’s background noise or accents.
- Lack of Customization: YouTube’s inbuilt subtitle creator has very limited styling options—plain white text isn’t exactly engaging.
This is where customized captions shine. Instead of relying solely on YouTube’s basic tools, you can use third-party apps like ZapCap to create captions that stand out.
How to Add Subtitles in YouTube Shorts
Now that you know why captions are crucial, let’s talk about how to add them. You have two main options: using YouTube’s subtitle creator or a tool like ZapCap.
Option 1: YouTube’s Inbuilt Subtitle Creator
YouTube provides an auto-caption feature that generates subtitles automatically. Here’s how to use it:
- Upload Your Short:
- Open YouTube Studio and upload your Short.
- Enable Captions:
- YouTube will auto-generate captions if your video includes clear audio.
- Edit Captions:
- Go to the “Subtitles” section in YouTube Studio.
- Review and edit the captions for accuracy.
Limitations
While it’s a free and simple option, you’re stuck with basic styling—plain text with no animation or customization.

- Eye-Catching Colors and Animations:
- Bright yellow text with bold outlines immediately grabs attention on a busy feed.
