Working with Music

DAD 310 — Fall 2026

The Mood chapter covers what music does to a scene. This lesson explains how to choose music, edit it to picture, and document permission to use it.

Temp music

Editors often work with temporary music before the score is finished. They may use existing scores, library tracks, or songs to stand in for the final music. The temp track helps establish the pace of the edit, gives test audiences music to respond to, and provides a reference for the composer.

Repeated exposure can make a director attached to the temp track and reluctant to accept a different musical approach. This is known as temp love, and it can push a composer toward imitating the reference track.

Use temp music to test ideas. Place a candidate track against the scene early, notice how it changes the pacing, and expect to replace it later.

Cutting music to picture

Music is organized by beats, phrases, and chord progressions. Keep that structure intact when editing a cue.

  • Cut in the quiet section just before a downbeat rather than at the beat’s peak. Cutting through the peak can truncate the transient and cause a pop.
  • Shorten a cue by removing whole phrases from the middle. Find the same beat of the bar at both edit points and join them with a short crossfade, about half a second. Listen through the join to check the edit.
  • End a cue at a cadence, a natural resting point in the music, or duck it under dialogue or a sound effect before fading it out. Avoid stopping the cue abruptly.
  • Allow music to continue across picture cuts. If every visual cut has a musical accent, the synchronization becomes distracting. Reserve those accents for selected cuts.

Use the same editing tools as before: splits, crossfades, and careful listening. Turn snapping off because the musical pulse may not align with REAPER’s grid.

For a scene about this collaboration from the composer’s side, watch the piano scene from Three Colours: Blue : as Julie and Olivier mark up a score at the piano, the full orchestration fades in as imagination made audible. The gap between the sketch they play and the cue they hear in their heads is the same gap between a temp track and a final score.

Licensing

A recorded song usually involves two copyrights: the musical work and the sound recording. Using both in a film generally requires permission from both rights holders.

Sync licenseThe compositionPermission to pair the written song, its melody and lyrics, with picture. Comes from the songwriter or publisher.
Master licenseThe recordingPermission to use one specific recorded performance of that song. Comes from whoever owns the recording, usually a label.

Student work is not automatically exempt from copyright requirements. Festivals may ask you to confirm that you have permission to use the music. An uncleared song can prevent you from screening, streaming, or submitting the film publicly.

Use one of these options:

  1. Compose and record the cue yourself. You have Vital and access to a studio. If all of the material is original, you control both the composition and the recording.
  2. Use a free library and read the license for the specific track. The YouTube Audio Library includes tracks that require attribution and tracks that do not. Pixabay permits music to be used in larger creative works without attribution, but you should keep a record of the download and license. Tracks on the Free Music Archive use different Creative Commons licenses. Check the attribution, commercial-use, ShareAlike, and NoDerivatives terms before choosing one. Synchronizing music to picture counts as an adaptation under Creative Commons licenses, so do not use a NoDerivatives track in a film you plan to share.
  3. Purchase a license from a service such as Musicbed or Artlist when the project warrants the expense.

Keep a note of every track’s source and license as you work. Your final project documentation requires it, and a festival may ask for the same information.

Lab: cut a cue to picture

Pick any scene you have, or a Blender short, and a track from one of the free libraries above.

  1. Lay the track against the scene as temp music and watch once. Note where it conflicts with the picture.
  2. Shorten the cue by at least eight bars by removing a middle section. The join must be inaudible.
  3. End the cue at a cadence or duck and fade it under another sound. Avoid an abrupt stop.
  4. Write down the track’s title, source, and license as if you were filling in a festival form.
