Words Per Minute
Notes

Standard narration
150 wpm
Conversational pace

Complex/technical
120 wpm
Allow processing time

Energetic/social
170 wpm
Faster for short-form

Children's content
100 wpm

**Key rule:** 1 scene per key message. Don't pack multiple ideas into one visual.

### Scene Duration Guidelines

- Establishing shot: 3-5 seconds

- Feature demonstration: 5-8 seconds

- Text/stat on screen: 3-4 seconds (must be readable)

- Transition: 0.5-1 second

- CTA screen: 3-5 seconds

## Visual Production

### Scene Types

```
# Product in context
infsh app run google/veo-3-1-fast --input '{
  "prompt": "Clean product demonstration video, hands typing on a laptop showing a dashboard interface, bright modern office, soft natural lighting, professional"
}'

# Abstract concept visualization
infsh app run bytedance/seedance-1-5-pro --input '{
  "prompt": "Abstract motion graphics, colorful data streams connecting floating geometric shapes, smooth fluid animation, dark background with glowing elements, tech aesthetic"
}'

# Lifestyle/outcome shot
infsh app run google/veo-3-1-fast --input '{
  "prompt": "Happy person relaxing on couch with laptop, smiling at screen, bright airy living room, warm afternoon light, satisfied customer feeling, lifestyle commercial style"
}'

# Before/after comparison
infsh app run falai/flux-dev-lora --input '{
  "prompt": "Split screen comparison, left side cluttered messy desk with papers and stress, right side clean organized minimalist workspace, dramatic difference, clean design"
}'

```

### Image-to-Video for Scenes

```
# Generate a still frame first
infsh app run falai/flux-dev-lora --input '{
  "prompt": "Professional workspace with glowing holographic interface, futuristic but clean, blue accent lighting"
}'

# Animate it
infsh app run falai/wan-2-5-i2v --input '{
  "prompt": "Gentle camera push in, holographic elements subtly floating and rotating, soft ambient light shifts",
  "image": "path/to/workspace-still.png"
}'

```

## Voiceover Production

### Script Writing Tips

- Short sentences. Max 15 words per sentence.

- Active voice. "You can track your data" not "Your data can be tracked."

- Conversational tone. Read it aloud — if it sounds stiff, rewrite.

- One idea per sentence. One sentence per visual beat.

### Generating Voiceover

```
# Professional narration with Dia TTS
infsh app run falai/dia-tts --input '{
  "prompt": "[S1] Tired of spending hours on reports that nobody reads? There is a better way. Meet DataFlow. It turns your raw data into visual stories... in seconds. Just connect your source, pick a template, and share. Try DataFlow free today."
}'

```

### Pacing Control in TTS

Technique
Effect
Example

Period `.`
Medium pause
"This changes everything. Here's how."

Ellipsis `...`
Long pause (dramatic)
"And the result... was incredible."

Comma `,`
Short pause
"Fast, simple, powerful."

Exclamation `!`
Emphasis/energy
"Start building today!"

Question `?`
Rising intonation
"What if there was a better way?"

## Music & Audio

### Background Music Guidelines

- **Volume:** 20-30% under narration (duck 6-12dB when voice plays)

- **Style:** match the brand tone (corporate = ambient electronic, startup = upbeat indie)

- **Structure:** intro swell (first 3s) -> subtle loop under narration -> swell at CTA

- **No vocals:** instrumental only under narration

```
# Generate background music
infsh app run <music-gen-app> --input '{
  "prompt": "upbeat corporate background music, modern electronic, 90 BPM, positive and professional, no vocals, suitable for product explainer video"
}'

```

## Assembly Pipeline

### Full Production Workflow

```
# 1. Generate voiceover
infsh app run falai/dia-tts --input '{
  "prompt": "[S1] Your script here..."
}'

# 2. Generate scene visuals (in parallel)
infsh app run google/veo-3-1-fast --input '{"prompt": "scene 1 description"}' --no-wait
infsh app run google/veo-3-1-fast --input '{"prompt": "scene 2 description"}' --no-wait
infsh app run google/veo-3-1-fast --input '{"prompt": "scene 3 description"}' --no-wait

# 3. Merge scenes into sequence
infsh app run infsh/media-merger --input '{
  "media": ["scene1.mp4", "scene2.mp4", "scene3.mp4"]
}'

# 4. Add voiceover to video
infsh app run infsh/video-audio-merger --input '{
  "video": "merged-scenes.mp4",
  "audio": "voiceover.mp3"
}'

# 5. Add captions
infsh app run infsh/caption-videos --input '{
  "video": "final-with-audio.mp4",
  "caption_file": "captions.srt"
}'

```
