What are the best practices for captions in real estate listing videos?

Real estate video caption best practices: display the property address in the first 3 seconds, use large bold sans-serif text (48pt+ equivalent) with high contrast (white text with dark shadow), keep individual caption phrases to 3–6 words for mobile readability while scrolling, include price and bed/bath count as mid-video overlays, position text in the upper 75% of portrait-format video to avoid platform UI overlap, and always end with visible agent name and contact number in the final 3 seconds.
