Audio Analysis: How AI Learns From Reference Videos
When you use Video Style Matching, AI analyzes the visual style of your reference video. But visuals are only half the story. Audio Analysis unlocks the other half.
What Is Audio Analysis?
Audio Analysis is an optional upgrade (+50 credits) available in the From Video generation mode. When enabled, AI doesn’t just analyze what the reference video looks like — it analyzes what it sounds like.
What Gets Analyzed
Music & Score
- BPM and tempo — the rhythm that drives the video’s energy
- Genre feel — electronic, cinematic, acoustic, lo-fi, orchestral
- Intensity curve — how the music builds, peaks, and resolves
- Key and mood — major/minor tonality, emotional character
Sound Design
- Ambient layers — background atmosphere, environmental sounds
- Product sounds — packaging, clicks, pours, textures
- Foley effects — swooshes, impacts, transitions
Pacing Cues
- Beat-sync editing — how cuts align with musical beats
- Energy shifts — where the audio drives scene changes
- Silence and space — intentional pauses for dramatic effect
How It Improves Your Video
Without audio analysis, AI generates a visually-matched video with generic audio. With audio analysis, the generated video:
- Matches the energy arc of the reference
- Uses similar musical genre and tempo
- Syncs visual cuts to audio beats
- Recreates the sonic mood — not just the visual mood
When to Use Audio Analysis
- Always for music-driven references (ads, reels, TikTok trends)
- Luxury/premium products where audio ambiance matters
- Food & beverage where ASMR-style sounds drive engagement
- Fashion where music sets the emotional tone
When to Skip It
- Budget-conscious generations where visual style matching alone is sufficient
- Reference videos with copyrighted music you don’t want to replicate
- Product demonstrations where audio is secondary
Cost
Audio analysis adds 50 credits to the generation cost. For most reference-based generations, the quality improvement is well worth the investment.
