Music Composer

Audio Expansion. Music Composer is part of Chat Video Pro’s Audio Expansion. It is included with the Creator Bundle and Creator Pass, and available as a DLC add-on for Base. Generations bill to your own fal.ai account at wholesale rates — same as the rest of Studio.

Music Composer is the soundtrack studio inside Premiere. One Launchpad card, three modes: write an instrumental bed, build a full song with structure and vocals, or Score a video so the music follows the picture you attach.

When to Use Music Composer

  • Background beds — underscore interviews, montages, or social cuts without hunting stock libraries

  • Original songs — verse/chorus structure, voice casting, and lyrics when you need a vocal track, not just ambience

  • Picture-locked scoring — attach a clip and generate a score timed to what is on screen

  • Stay in Premiere — generate, audition, Add to Chat, and place on the timeline without bouncing through browser tabs

Getting Started

Step 1: Open Music Composer

  1. Open Chat Video Pro (Window → Extensions → Chat Video Pro)

  2. Click Studio in the sidebar to open the Launchpad

  3. In the Audio department, click the Music Composer card

You land on three mode tabs: Instrumental, Song Builder, and Score a video.


Mode: Instrumental

Best for beds, underscore, and lyric-free soundtrack.

Step 2: Details — Describe your music

  • Write what you want to hear (mood, instruments, energy, use case). Aim for at least a clear sentence — short, vague prompts produce generic beds.

  • Optional: enable the background music style when you want lower-energy underscore that sits under dialogue.

  • Tap the sparkle (AI Optimize) to tighten the prompt, then Continue.

Step 3: Style — Model & duration

Pick an engine and a duration, then click Generate Music.

Model
Best for
Duration

Lyria 3 Pro

High-quality instrumental beds

Fixed length (duration control may not apply)

MiniMax Music 2.6

Flexible instrumental generation

Fixed length (duration control may not apply)

ElevenLabs Music

Prompt-driven soundtrack

About 5–150 seconds

Stable Audio 3

Longer beds and atmospheres

About 5–380 seconds

If exact length matters for your cut, prefer a model that honors duration (ElevenLabs Music or Stable Audio 3), then trim in Premiere if needed.

Step 4: Result

Preview under Your music, then:

  • Add to Chat — primary handoff into the conversation / Library

  • Place on timeline — inserts at the playhead on a free audio track

  • Try Again — regenerate with the same setup


Mode: Song Builder

Best when you want structure and vocals — not just a loop.

Step 2: Details — Build your song

  • Add song sections (Intro, Verse, Pre-Chorus, Chorus, Post-Chorus, Hook, Bridge, Break, Outro).

  • Fill lyrics per block (or use Magic to draft lyrics from your idea).

  • Tap AI Optimize when you want help polishing lyric/style language, then Continue.

MiniMax lyric path has a practical ceiling around 3,500 characters of lyrics. If Generate stays disabled, shorten the lyric blocks or switch to ElevenLabs Music for the song path.

Step 3: Style — Voice & model

  • Choose a vocal voice casting option.

  • Pick MiniMax Music 2.6 or ElevenLabs Music.

  • Click Generate Song.

Step 4: Result

Same handoff as Instrumental: preview, Add to Chat, Place on timeline (playhead), Try Again.


Mode: Score a video

Best when the music should follow a specific clip — trailers, social cuts, picture-locked sequences.

Step 2: Attach a clip

The empty state opens the clip loader titled Score a video. Choose:

  • Upload — video file from disk

  • Recent — a video you used or generated recently in Chat Video Pro

  • Import Clip — pull the selected clip from the active Premiere timeline (best when you want the score placed back under that clip)

Step 3: Optional style notes → Generate Score

  • Add short Style notes (optional) — genre, mood, instruments, or “sparse under dialogue.”

  • Use AI Optimize if you want the notes tightened for scoring.

  • Click Generate Score (shows Preparing… while the clip uploads and the score is planned).

Music Composer watches the clip, builds a composition plan behind the scenes, and generates a synced score. You do not edit the plan in this release — steer with style notes and regenerate if needed.

Step 4: Result — Your scored video

  • Preview the muxed video with the score

  • Download video with score — export the muxed preview

  • Download audio — score-only file from the audio pill

  • Add to Chat — promotes the audio and the muxed video into chat

  • Place on timelineunder the source clip when you used Import Clip (timeline start was captured); otherwise at the playhead

  • Try Again

Tips for Best Results

  • Be specific about role (“sparse piano under interview,” “driving drums for montage,” “warm acoustic for brand film”).

  • For Score a video, prefer Import Clip when the music must land under a known timeline position.

  • Keep Score clips under three minutes; cut selects before attaching.

  • Use AI Optimize when your prompt is a vibe dump — it turns loose notes into a usable brief.

  • Audition in the panel, then place — Place does not auto-duck dialogue.

Troubleshooting

Symptom
What to try

Generate stays disabled

Prompt too short, lyrics over the MiniMax cap, or clip over 180s for Score

Duration doesn’t match what you set

Switch to ElevenLabs Music or Stable Audio 3; some engines ignore duration

Score feels off-picture

Tighten style notes, regenerate, or attach a cleaner / shorter select

Place lands at the playhead, not under the clip

Re-attach with Import Clip so timeline start is captured

Engine / network errors

Confirm fal.ai key + balance in Settings → Usage, then Try Again
