Explain Video: AI Video Generation Guide

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:

  1. Upload your existing video (MP4, WebM)
  2. Transcribe the audio using AI speech recognition
  3. Translate the transcript to any target language
  4. Re-dub with AI voices synchronized to the original timeline
  5. Export the new video with replaced audio

This workflow supports 26 languages and maintains the original video's pacing.

Tips for Great Explainer Videos

  1. Keep it concise — 2-3 minutes is the sweet spot for engagement
  2. Structure your content — Introduction → Key points → Summary
  3. Use clear language — Simple sentences produce better narration
  4. Review the script — Edit the AI-generated script before video production

CLI Integration

Power users can automate video creation via the CLI:

# Translate and dub a video
voxflow video-translate input.mp4 --target-lang zh-CN --output dubbed.mp4

# Transcribe a video
voxflow asr video.mp4 --output transcript.srt
