How To Create a complete Soundtrack for a Film in One Hour With… AI

Hey friends,

So here’s the thing. Scoring a film or a short used to be this huge process, expensive, time-consuming, full of back-and-forth. Now? I’ve been running a workflow where we can get a full demo score done in about an hour. Seriously. This isn’t about replacing composers…I am a composer myself! it’s about giving them a head start. Like strapping a jetpack on their process.

Here´s a taste of the result:

Here’s how I do it. Start by uploading the shooting script into ChatGPT. Ask it where music could help carry emotion, moments where music would lift the scene. For each of those, ask Chat GPT to generate 3–4 prompts to create the music for those scenes. Then take those prompts and drop them into Udio at www.udio.com.

Once you’ve got your prompts, Udio does the heavy lifting. Paste, click generate, wait a few seconds. Each prompt gives you a stereo file. Do that 3 times per scene and move to the next one. You can get 30–40 music cues in an hour if you keep the flow tight. And yes, the audio’s royalty-friendly, but always check the license.

Say something like “Give me a list of where score would elevate the story. Include genre, mood, tempo, instruments, and duration.” You’ll get stuff like “Tense synth pulse, 96 BPM, 45s” or “Sparse cello over reversed piano, 70 BPM, 60s.” Short, punchy, clear. That’s what works.

You’ll get full-on music cues in 40 seconds. Organize them by scene, audition them against picture, export your favorites. If a cue’s off, just tweak the prompt and regenerate.

Keep your script clean, scene headers like “INT. BAR — NIGHT” help the AI spot structure. If you’ve got storyboards, even better. They give visual mood that sharpens the AI’s choices. And always spellcheck. The AI handles noise well, but the wrong word can throw it off.

Then you go into curation mode. Drop the audio into your timeline, check how it plays against picture. Does it breathe with dialogue? Does it hold emotion without overselling it? Tag your cues… green for good, orange for maybe, red for no. If it’s close, tweak and regenerate. Don’t get lost in 20 versions, batch your fixes and stay moving.

Always grab the stems when exporting from Udio. That way, if you need to mute a hi-hat or stretch a riser, you can. If a human composer joins later, give them the stems and the original prompts. That combo is the new hand-off format. It’s clear and saves loads of time.

This approach is also a legal win. Instead of temporary tracks you can’t clear, you’re starting with original stuff. So directors hear something emotional and aligned, and you’re not stuck chasing rights or trying to sound like Radiohead but not exactly.

Keep a log of your prompts. Run similarity checks. If AI wrote 80% and a composer shaped the rest, credit both. Fair is fair.

Some quick tips: The AI respects tempo and genre tags. Keep your prompts organized. If your director hates glitchy stuff, say: “organic, no vocals” in the prompt. And name your files clearly: SC23_P2_V1_96BPM.wav” will save you at 3am.

Once in the DAW (Logic, Cubase, Pro Tools), create a master folder, drop in your files by scene, and stack three versions per spot. Solo through them live during the spotting session. When the director picks one, promote it and clean it up with a touch of EQ and compression.

Looking forward, we’re gonna see tools that generate cues live inside your editing software. Maybe even regenerating them on the dub stage. It’s coming fast. But no matter the tech, keep one thing in mind…music is emotion. Silence is emotion too. Use both wisely.

We in the Nordics love space and clarity in sound. Let that vibe guide your prompts. Write things like “fjord sub bass” or “icy tail reverb.” Global tools. Local flavor. haha

So try it, tweak it, break it, rebuild it. Share what works. Let me know how it goes…and also…I would love your opinion on this method.:-)
