Adding Captions to Videos

Prerequisites

  • An OpenClip account (Starter, Pro, or Business plan)
  • A video file in MP4 or MOV format, or a hosted video URL
  • Clear audio in your video for best transcription accuracy

Steps

1

Create your OpenClip account

Sign up for an OpenClip account on the web at openclip.app. Choose the plan that fits your needs — Starter, Pro, or Business. Once logged in, you'll land on your project dashboard.

Tip: You don't need any video editing experience to get started. OpenClip handles the technical work automatically.

2

Upload your video

Click 'Upload Video' on your dashboard and drag and drop your video file, or browse to select it from your computer. OpenClip accepts MP4, MOV, and other common video formats. You can also paste a direct video URL if your content is hosted online.

Tip: MP4 files with H.264 encoding upload and process the fastest. Keep file sizes under 5GB for best results.

3

Let AI generate your transcript

Once your video is uploaded, OpenClip's AI speech recognition automatically transcribes every spoken word with timestamps. This usually takes just a few minutes depending on video length. You'll see a word-level transcript appear when processing is complete.

Tip: If your video contains names, acronyms, or industry jargon, review the transcript carefully — AI can occasionally mishear uncommon words.

4

Choose a caption style preset

OpenClip offers 10 professionally designed caption presets: Default, Dan, Dan Reveal, Pop, Mozi, Kendrick, Sara, Lucy, Tayo, and Beast. Each preset has its own font, color scheme, animation style, and layout. Click through the presets to preview how they look on your video before committing.

Tip: Bold, high-contrast styles like Pop or Beast tend to perform best on TikTok and Instagram Reels where viewers watch with sound off.

5

Customize caption appearance

After selecting a preset, you can fine-tune the caption styling — adjust highlighting colors, toggle emoji injection on or off, and position captions within the safe zone of your video frame. This ensures captions are visible and don't get cut off on any platform.

Tip: Keep captions in the lower-center safe zone to avoid interference with platform UI elements like like buttons and usernames.

6

Export your captioned video

When you're happy with your captions, click 'Export.' Select your desired format — vertical 9:16 for TikTok and Reels, or horizontal . Your captioned video will download ready to publish.

Tip: Export the same video in multiple aspect ratios at once to repurpose across all your platforms in one step.
