Make the opening understandable without sound
The first caption should state or reinforce the hook rather than warm up slowly. A viewer should understand the problem or promise from the opening seconds.
Treat claims and numbers as high-risk words
Proof points, prices, percentages, dates, and product names need manual review. A visually polished ad with an incorrect caption still loses trust.
Design for changing backgrounds
Use an outline, shadow, or solid backdrop that keeps the words readable across light and dark shots. Preview the entire ad, not only the opening frame.
Keep a clean version for each placement
Platform interfaces occupy different areas. Position captions inside the usable frame and preserve source projects so placement can be adjusted for another placement when necessary.
