Captions Checklist for Explainer Reels: Readable, Accurate, Brand-Safe

Captions Checklist for Explainer Reels: Readable, Accurate, Brand-Safe To ensure your explainer Reels are effective even when watched muted, it's crucial to have accurate, readable, and brand-safe captions. This checklist covers the essential steps for creating high-quality captions, including source accuracy, chunking and timing, placement and safe zones, typography and contrast, mute-first comprehension, accessibility extras, localization captions, and brand and legal safety.

What Makes Effective Captions? Effective captions are those that provide a clear and accurate representation of the audio content, are easy to read, and do not distract from the visuals. They should be brand-safe, meaning they align with the company's style and tone, and should not introduce any misleading or false information.

How to Achieve Source Accuracy Source accuracy refers to the captions matching the final voiceover (VO) take. To achieve this: Generate auto-captions and then have a human review and correct them. Ensure product names use official capitalization. Verify numbers match approved claims. Check for hallucinated words from auto-caption errors.

What is the Ideal Chunking and Timing for Captions? Chunking and timing are critical for readability. Best practices include: 1-2 lines on screen at a time for vertical video. Approximately 32-42 characters per line. Phrases broken at natural language boundaries, not mid-word. Captions appearing roughly with speech, without lagging a full second behind. * Holding captions long enough to read, especially for technical terms.

Read-Time Gut Check For chunks with new terms and numbers, give them more hold time than simple connector phrases. This ensures the viewer has enough time to read and understand the content.

How to Place Captions Safely Captions should be placed in a consistent vertical band, often in the center-lower part of the screen, to avoid: Random jumps every clip. Platform UI elements like usernames, buttons, and engagement bars. Covering faces, product details, or diagram labels that matter. Duplicating captions if using both burned-in and platform captions.

What are the Best Practices for Typography and Contrast? For optimal readability: Use a brand-approved font or a clean sans-serif font. Ensure the font weight is bold enough for mobile devices. Use sufficient contrast, such as light text on a dark background, with a stroke or blur plate if needed. Avoid rainbow word-by-word gimmicks and emphasize key terms sparingly.

How to Ensure Mute-First Comprehension Mute-first comprehension means a viewer can follow the content with captions and visuals alone. To achieve this: Ensure essential words are not only in the VO. Number steps in captions if visual numbering is easy to miss. * Test the video with sound off before finalizing.

What Accessibility Extras Should be Included? Accessibility extras enhance the viewing experience for all users. Consider: Speaker labels for multiple voices. Non-speech audio cues captioned when meaningful. Avoiding reliance on color alone for meaning in caption highlights. Providing a plain transcript on the landing page or post text for complex topics.

How to Handle Localization Captions For localized content: Translate captions and time them to the localized VO. Recheck line breaks, as languages like German and Finnish may require different chunking. Translate or remove on-screen burned text. Review cultural examples to ensure they are appropriate and not just dictionary translations.

Caption QA Ritual Perform the following 8-minute QA ritual: 1. Auto-sync and correct errors. 2. Watch the video muted. 3. Preview in the native app for safe zones. 4. Spot-check dense chunks for read time. 5. Compare caption claim language to the approved script. 6. Export the style preset for the series.

Style Presets to Save Document the following for your team: Font, size, and weight. Fill, stroke, and background plate. Position Y%. Max lines. Emphasis color (brand accent). Words to always uppercase or never uppercase.

Common Failures and Fixes | Failure | Fix | |---------|-----| | Double captions | Turn off one source. | | Inaccurate captions | Review and correct auto-captions. | | Poor readability | Adjust font size, weight, and contrast. |

Worked Example: Creating Captions for an Explainer Reel Let's say we're creating an explainer Reel for a new product launch. The final VO take is ready, and we need to create captions. First, we generate auto-captions and then have a human review and correct them. We ensure product names use official capitalization and verify numbers match approved claims. We then check for hallucinated words from auto-caption errors and correct them.

Next, we chunk the captions into 1-2 lines per screen, with approximately 32-42 characters per line. We break phrases at natural language boundaries and ensure captions appear roughly with speech. We hold captions long enough to read, especially for technical terms.

We place the captions in a consistent vertical band, avoiding platform UI elements and ensuring they don't cover important visuals. We use a brand-approved font, bold enough for mobile devices, and ensure sufficient contrast.

Finally, we test the video with sound off to ensure mute-first comprehension and perform the caption QA ritual to catch any errors.

Ship Checklist Before shipping your explainer Reel, ensure you have: Created accurate and readable captions. Checked for brand and legal safety. Performed the caption QA ritual. Documented style presets for your team. Tested the video with sound off for mute-first comprehension. Included accessibility extras and localization captions as needed.
