Great video is only half the experience. The right audio transforms good visuals into unforgettable content. Here's how to master the audio-visual combination.

Why Audio Matters

The Psychology

• Music triggers stronger emotions
• Audio creates memory anchors
• Sound design implies quality

The Engagement Impact

• Videos with music see 30% higher engagement
• Sound-on viewers watch 4x longer
• Audio recall exceeds visual recall
• Music makes content shareable

Matching Music to Visuals

Energy Matching

High Energy Visuals:

Dynamic motion, bright colors, fast action

→ Upbeat music, strong beats, 120+ BPM

Calm Visuals:

Slow motion, soft colors, gentle movement

→ Ambient music, soft melodies, 60-90 BPM

Dramatic Visuals:

Cinematic scenes, bold contrasts, sweeping motion

→ Orchestral, building dynamics, emotional swells

Mood Alignment

Creating Visual Prompts for Music

Music-First Approach

If you already have a track, create visuals to match:

For upbeat pop track:

Bright, colorful scene with dynamic movement, matches upbeat energy, pop music visual, energetic and fun

For ambient track:

Slow, peaceful scene with gentle motion, ambient music visual, calm and flowing, matches meditative audio

For cinematic orchestra:

Epic, sweeping scene with dramatic movement, cinematic visual, orchestral energy, grand and emotional

Visual-First Approach

Create music search terms based on your visuals:

| Your Visual | Search Terms |

|------------|--------------|

| Ocean waves | "Calm ocean ambient" "Peaceful waves" |

| City timelapse | "Urban electronic" "City beats" |

| Product showcase | "Corporate uplifting" "Product reveal" |

| Cozy interior | "Lo-fi chill" "Cozy acoustic" |

| Nature landscape | "Cinematic nature" "Epic ambient" |

Sound Design Beyond Music

Ambient Sound

When to use: Creating atmosphere, realism, immersion

Prompt enhancement:

[Scene] with implied ambient sound, [sounds you'd hear], atmospheric and immersive

Examples:

• Rain scenes → rain ambient
• Café scenes → coffee shop sounds
• Nature scenes → wind, birds, water
• Urban scenes → city ambient, traffic

Sound Effects

When to use: Emphasizing moments, transitions, impacts

Key moments for SFX:

• Reveals (whoosh)
• Impacts (hit, thud)
• Transitions (swoosh)
• Achievements (sparkle, ding)

Silence

When to use: Creating tension, emphasizing moments, breathing room

Strategic silence can be more powerful than constant audio.
