VoxFlow's Explain Video feature lets you create professional explainer videos by combining AI narration with generated visuals. This guide walks you through the end-to-end process.
What is Explain Video?
Explain Video takes a topic or script and produces:
- AI-generated narration using VoxFlow's TTS engine
- Animated scenes with key points and visuals
- Synchronized subtitles for accessibility
- Background music that matches the tone
The result is a polished video ready for social media, presentations, or educational content.
Creating Your First Explain Video
1. Choose Your Topic
Provide a clear topic or detailed script. The AI works best with specific subjects:
- ✅ "Explain how blockchain works in simple terms"
- ✅ "5 tips for better public speaking"
- ❌ "Everything about technology" (too broad)
2. Select a Theme
Choose from available visual themes:
- Modern — Clean, minimalist design with gradient accents
- Playful — Colorful, animated elements for casual content
- Corporate — Professional, business-appropriate styling
- Chalkboard — Educational, classroom-style visuals
3. Configure Voice and Language
Select the narration voice and language. The video automatically adjusts:
- Subtitle language
- Text direction (LTR/RTL)
- Scene timing based on speech length
4. Generate and Export
Click generate and wait for processing. Depending on length, this typically takes 1-3 minutes. Export options include:
- MP4 — Standard video format (1080p)
- WAV — Audio-only export
- SRT — Subtitle file for external use
Video Dubbing Integration
Already have a video? Use Video Dubbing to:
- Upload your existing video (MP4, WebM)
- Transcribe the audio using AI speech recognition
- Translate the transcript to any target language
- Re-dub with AI voices synchronized to the original timeline
- Export the new video with replaced audio
This workflow supports 26 languages and maintains the original video's pacing.
Tips for Great Explainer Videos
- Keep it concise — 2-3 minutes is the sweet spot for engagement
- Structure your content — Introduction → Key points → Summary
- Use clear language — Simple sentences produce better narration
- Review the script — Edit the AI-generated script before video production
