Creating Accessible Video Captions

Prerequisites

An OpenClip account (Starter plan or above)
A video file in MP4 or MOV format, or a video URL
Basic familiarity with the OpenClip dashboard

Steps

Upload your video to OpenClip

Log into your OpenClip account and upload your long-form or short-form video. Drag and drop an MP4 or MOV file, or paste a video URL directly into the dashboard.

Tip: Clear, high-quality audio produces the most accurate AI transcription — minimizing the manual corrections needed later.

Generate AI captions automatically

OpenClip's AI transcription engine processes your video and generates word-level captions synced precisely to each spoken word. The transcript appears in your dashboard for review.

Tip: Scan the transcript for proper nouns, brand names, and technical terms that AI may mishear — these are the most common correction points.

Review and edit the transcript

Go through the generated transcript and correct any errors. For accessibility, accuracy is critical — viewers relying on captions depend on every word being correct. Pay special attention to speaker changes, names, and numbers.

Tip: Read the captions aloud while watching the video to catch any timing or wording issues that are easy to miss on a silent pass.

Choose a high-contrast, readable caption style

Select a caption preset that prioritizes readability. For accessibility, choose styles with strong contrast between text and background — such as white text on a dark semi-transparent background. OpenClip offers 10 caption presets to choose from.

Tip: The 'Default' and 'Pop' presets offer strong contrast and clean fonts that meet general readability best practices for accessibility.

Position captions in the safe zone

Use OpenClip's safe-zone positioning to place captions where they won't overlap with important on-screen content or platform UI elements. Captions should be visible regardless of where a viewer watches.

Tip: Bottom-center placement is the most universally expected caption position and the most comfortable for viewers to read.

Export your captioned video

Export your video in your desired format (9:16 for Shorts/Reels/TikTok/LinkedIn). OpenClip burns the captions into the exported video so they're always visible.

Tip: Export in the highest resolution available to ensure captions remain sharp and legible on all screen sizes.

Frequently Asked Questions

Accessible captions ensure your content is inclusive for viewers who are deaf or hard of hearing, watching in sound-sensitive environments, or are non-native speakers. They also improve SEO and viewer retention by making content easier to follow.

Accessible captions are accurate (matching exactly what is spoken), synchronized (timed correctly to speech), readable (high contrast, appropriate font size), and consistently positioned so viewers can follow without effort.

OpenClip's AI transcription achieves high accuracy for clear audio in supported languages. For accessibility purposes, we always recommend reviewing and correcting the transcript before exporting — especially for names, acronyms, and technical terminology.

Yes. OpenClip's speaker diarization identifies different speakers in your video, which helps maintain caption accuracy in interviews, panels, and multi-person conversations.

For maximum accessibility, choose a preset with strong contrast — white or yellow text against a dark semi-transparent background. The 'Default' and 'Pop' presets are good starting points. Avoid overly decorative styles that may reduce legibility.

OpenClip burns captions directly into the exported video. For SRT file workflows, refer to our SRT file guide for more on how to work with external caption files.

Burned-in captions add minimal overhead to your video file size since they're rendered into the video frames during export. The increase is typically negligible compared to the overall file size.
