Frequently Asked Questions About Filmora Dynamic Caption
- What is Filmora's Dynamic Caption (auto caption) feature?
-
Dynamic Caption is Filmora's AI-powered auto caption generator. It transcribes the audio of your video with Auto-Detect Language, applies smart sentence segmentation aligned to natural speech pauses, auto-highlights words and phrases with animated effects (Active Words + Key Words), and can translate captions to 30+ languages — all in one click. You then refine in a 6-tab property panel with full font, template, animation, keyframe, and 3D spatial-text control.
- Does Filmora have auto captions?
-
Yes. Filmora's built-in Dynamic Caption tool automatically generates captions from any video or audio file. Just import your video to the timeline, open Titles → AI Captions → Dynamic Caption, click Generate. Captions appear on the timeline within 30-60 seconds, synchronized to speech with animated effects already applied.
- Is Filmora's auto caption tool free?
-
Generating new captions uses AI credits (a starter pack is included free when you install Filmora). Once captions are generated, all editing — text changes, 100+ templates, 120+ animations, 13 keyframe properties, 3D spatial offset, multi-track styling, translation refinement — is completely free and unlimited.
- How accurate is Filmora's auto caption generator?
-
Filmora's Dynamic Caption delivers up to 99% transcription accuracy for clear audio, with smart sentence segmentation that aligns subtitle breaks to natural speech pauses. The AI handles multiple speakers, accents, and technical terminology. Most users only need minor edits; you can use bulk find-and-replace to quickly refine terminology across the entire video.
- What languages does Filmora's auto caption support?
-
Transcription supports 50+ source languages with Auto-Detect Language enabled by default (no manual setup needed), and you can translate captions to 30+ target languages in a single click, including Spanish, French, German, Hindi, Marathi, Bengali, Tamil, Portuguese, Japanese, Korean, Arabic (with RTL support), and more.
- What are Active Words and Key Words highlights?
-
Dynamic Caption includes two independent highlight modes you can toggle on/off. Active Words: each word highlights one-by-one in karaoke style as it's spoken, synced to audio rhythm — ideal for short-form social videos and lyric-style captions. Key Words: AI automatically detects important words and phrases (subject terms, emphasized phrases) and highlights them distinctly. Both can be enabled together or used independently. Customize highlight colors, animations, and keyframe motion in the property panel.
- Can I customize the look of auto captions?
-
Absolutely. After generation, captions come with a built-in font template applied. From there you can access the 6-tab property panel: pick from 100+ Templates, choose from 120+ Animation presets (In/Out/Loop across Motion & Path, Mask & Reveal, Fluent, Build, and Stylized categories), adjust font/color/size/background, apply 13 text keyframes, add 3D spatial offset (0-360°), use Bubble caption styles, and apply Track-level Apply to All for safe batch styling across multi-track projects.
- Can I translate captions in Filmora? What if I need full video dubbing?
-
For caption-only translation in 30+ languages, use Dynamic Caption's built-in Translate To option — timing and natural segmentation are preserved across languages, and the translation generates as a synchronized auxiliary subtitle track displayed alongside the original. The original-language caption keeps its full Dynamic Caption styling (Active Words, animations, templates); the translated track shows as clean reference text. If you need full video dubbing with voice cloning and lip-sync of the actual speaker, use Filmora's separate AI Video Translation feature, which generates spoken audio in the target language matched to mouth movements.
