Music for Reels and ads

Music for a Reel or an ad should match the video's length and mood, sit at the right level under everything else, and come with a license that covers how you will use it. The tracks in the Motion Cheat Code pack were made in code for the pack and are cleared for commercial use, including paid ads, and each one comes as a seamless loop, 15, 30 and 60-second edits with a real ending, and three stems.

This guide covers how to choose a track and which file to use, then the levels and loudness that work on phone speakers.

What the license covers

The pack's license lets you use the music in unlimited videos for yourself and your clients, including paid ads, forever. You may edit and remix it. You may not share, resell or publish the music files themselves, alone or inside another pack or library, and each person who uses them needs their own copy. This page describes the pack's license only; it is not legal advice and says nothing about any platform's own rules.

Pick by BPM and mood

Every track is named loop-<name>-<bpm>, and the number at the end is its tempo in beats per minute (BPM). Tempo sets the pace of the edit: one beat lasts 60 / BPM seconds, so at 124 BPM a beat is 0.48 s and a cut every two beats lands about once a second. Fast tracks suit fast cuts; slow tracks suit slow reveals and voice-overs.

A few examples from the pack's music list:

Match the mood to the look as well as to the message. A slow, elegant design under a hard, dark beat feels wrong even when the tempo fits. The music page lists every track with its tempo, key and what it is good for.

Use the loop or an edit

Each track comes in two shapes:

• The edits, 15, 30 and 60 seconds long, have an intro feel and a real ending. Use one when your video has that length, so the music finishes with the picture instead of being cut off mid-phrase.
• The loop is a whole number of bars, so copies placed end to end join without a bump (see seamless loop). Use it for any other length: place copies back to back, trim the last one at the end of the video and fade out.

If the video ends in the middle of a bar, you can also adjust its length to end on a full bar. A bar is four beats, 4 x 60 / BPM seconds: 1.94 s at 124 BPM.

In HyperFrames, music is one <audio> tag like any other sound:

<audio id="music" src="music/loop-house-pump-124.wav" data-start="0" data-volume="0.8"></audio>

Or ask Claude Code in one sentence: "Loop the music to the full length of this video with a 1.5-second fade-out."

Use the stems under a voice

The three stems are the drums, the bass and the rest of the music as separate files. They let you change the arrangement, not only the volume: mute the drums under a voice so the words stay clear, keep only the bass for tension before a reveal, then bring everything back for the end card. More in the glossary entry on stems.

Set the level

Starting volumes in HyperFrames (data-volume, where 1.0 is the file as it is):

In an editor that shows decibels, start the music about 14 dB below the voice. Better still, duck it: lower the music while someone speaks and let it rise again in the pauses. Ducking keeps the energy of the track without fighting the words. In a project with a voice, one sentence does it: "Add music/loop-chill-keys-84.wav under my voice and duck it while I speak."

The order to remember: music under, effects on top, voice above everything. For timing effects to the beat of the track, see adding sound effects on the beat.

Check the loudness

The tracks are mixed to about -14 LUFS with the true peak below -1 dBTP, so a track on its own already sits at a common target for social video. Once you add a voice and effects, measure the finished render:

ffmpeg -i renders/final.mp4 -af ebur128=peak=true -f null -

Aim for about -14 LUFS integrated with the true peak below -1 dBTP; see LUFS and true peak. Then listen once on a phone speaker. If it sounds crowded, turn the music down before you touch the voice.

Files and formats

Each loop is a WAV file at 48 kHz, 16-bit stereo, plus an MP3. The edits and the stems are MP3 files at 320 kbps. Use the WAV in a HyperFrames project and the MP3s in a phone editor.

Where to get the tracks

The free starter kit has five sound effects but no music. All 30 tracks, each with its loop, edits and stems, come with the full pack.
