Part 1. Dynamic Subtitle – What Are Captions and Audio Ducking
Dynamic captions are on-screen text that show what people say and what sounds you hear. They help people who cannot hear well and aid in noisy or very quiet places. Additionally, they make it easy for people who do not know the language well, showing words alongside the speech.
On the contrary, audio ducking is a way to lower one sound so another sound stays clear. Besides, it often lowers the music when someone speaks, which helps speech stay easy to hear and keeps the sound balanced.

Part 4. Best Practices for Creating Dynamic Subtitles in Filmora
As you learn how to create dynamic subtitles, follow the 5 listed practices to get the foremost outcomes in 2026:
- Plan captions: Always start with a clean audio file so captions stay accurate, as high-quality sound helps AI produce better text. Additionally, place the text away from the screen edges so no text is cut off.
- Clear text: Choose simple fonts that look clean across all screens and keep the text large, so it stays easy to read. Additionally, pick a strong contrast, like light text on dark, and add a shadow or a box to make the words stand out.
- Soft motion: Add small motion, like a fade or slide, for style, and keep it smooth so the text stays easy to follow. Moreover, it’s better to use one main style for all text and focus only on keywords so they stand out more.
- Fix timing: Match each line to speech so the words feel right, and use timeline tools to place text in the correct spot. Keep the text on screen long enough to read, and avoid very fast changes that are hard to follow.
- Set position: Place the text near the bottom, but not too low; move it up if other graphics take that space. Finally, check vertical videos so apps do not cover text, and keep faces and main visuals clear at all times.
