What Is Captioning?

Captioning is the process of adding synchronized on-screen text that transcribes a video’s spoken words and important sounds. It’s one of the highest-impact, lowest-effort upgrades you can make to any video.

Open vs. closed captioning

There are two ways to caption a video:

• Closed captioning — supplied by a separate file the viewer can toggle on or off. Great for accessibility and supported across platforms.
• Open captioning — text burned permanently into the video frame, always visible. Best for social feeds where most people watch on mute.

Many creators use both: closed captions where platforms support them, and burned-in animated captions on short-form clips.

Why captioning is worth it

Captioning pays off in three ways:

• Accessibility — it makes your content usable for deaf and hard-of-hearing viewers.
• Watch time — with most social video watched silently, captions keep viewers engaged through the whole clip.
• Discoverability — platforms and search engines can read caption text to understand and surface your content.

Captioning at scale

Manual captioning — transcribing, timing, and styling every line — is the slow part. quso.ai’s AI caption generator automates it: it transcribes your video, lets you edit, and burns accurate, on-brand captions onto your clips or exports a caption file. That turns hours of captioning into a few minutes per video.
