How to Add Music to a Video with Valmera

1. 1
   Upload your video

   Drag in any video up to 2GB (up to 3 hours). Valmera analyzes it once with visible progress — including where you speak, so music can duck under your voice from the first request.
2. 2
   Type the request

   Type something like "add an upbeat track from the library and duck it under my voice", "put this song under the whole video and fade it out at the end", or "loop the chill track at 20% volume". The agent picks or imports the music, places it, and mixes it.
3. 3
   Preview, refine, export

   Watch the preview and adjust in plain English — "a bit quieter", "start the music at 0:05". Then export a full-quality MP4 rendered from your original upload, with only a small corner mark on the free plan.

The upload is analyzed once with visible progress; after that, every music change is a single chat message.

A Royalty-Free Music Library, Built In

Valmera ships a library of 24 royalty-free tracks released under CC0 — no royalties, no attribution requirement, cleared for commercial use — organized across 8 moods: upbeat, chill, cinematic, corporate, dramatic, hip-hop, ambient, and inspiring. You don't browse and audition files; you ask. "Add a cinematic track under the intro" is a complete instruction — the agent picks a fitting track, and if you'd rather hear another option, "try a different one" is the whole workflow.

Every track supports volume control, fade-in and fade-out, looping for long videos, and a start offset — all by request. The full parameter list lives in the audio and music docs.

Auto Ducking: Background Music That Makes Room for Speech

The most common background-music mistake is a track that fights the voice. Valmera ducks music under speech using sidechain compression — the technique an actual mix engineer would use. The music dips smoothly while you talk and swells back in the pauses, instead of snapping between two volume levels. It applies to the original speech in your footage and to any voiceover you add on top, which auto-ducks the other layers under it.

Every layer — original audio, music, voiceover — also has independent gain, so "music at 15%, voiceover full" is one sentence, not a mixing session.

Add Your Own Song — Upload a Track or Paste a Link

The library is a starting point, not a cage. Upload your own audio — up to 50MB per track — or paste a link in chat and the agent pulls the media into your edit. Imported tracks get the same treatment as library ones: placement anywhere in the video, fades, looping, offset, ducking, and per-layer volume.

Make sure you have the rights to any music you bring. The built-in CC0 library exists precisely so there's always a safe default.

Find the Drop, Cut to the Beat

Valmera doesn't just play the music — it listens to it. Ask "where's the drop in this song?" and the agent analyzes the track and tells you, so you can line the drop up with your reveal using a start offset. Ask for beat-synced cuts and the agent snaps your cut points to the musical beat — and if a track has no reliable tempo to lock onto, it says so honestly instead of guessing.

For the full rhythm-and-impact treatment — whooshes at cuts, an impact on the strongest word, a riser building into the energy peak — there's a one-request sound-design pass on the AI sound effects generator side of the toolset.

Master the Mix to Platform Loudness

A good music bed can still sound wrong if the overall mix is too quiet or clips. One mastering request targets −14 LUFS with a −1.5 dBTP true-peak ceiling — the loudness platforms normalize to — so your video holds its own next to professionally produced content instead of getting turned down by the platform or sounding thin on phone speakers.

What This Tool Won't Claim

Two honest limits. First, Valmera does not generate AI music or songs — the soundtrack comes from the CC0 library, your uploads, or pasted links. Second, if music is already baked into your video's single original audio track, it can't be separated from the speech in that track; the practical fix is to mute the original audio and rebuild the sound with a clean track on top.

Everything this page does claim is enforced by Valmera's honesty layer: every agent reply is verified against the edits actually made, so "I ducked the music under your voice" is never a guess.

More Than an Add-Music Tool

The music request usually isn't the whole job — and here it doesn't have to be. The same chat cuts silences, styles word-accurate captions, reframes for 9:16, grades the color, and adds zooms and transitions. Browse all the AI video editing tools — each one is the same agent, pointed at a different request.
