Alright, let's cut through the usual "AI music is magic" hype. You're asking about scoring *scenes*, which is a more specific and interesting challenge than just generating a random track.
Udio can be suitable, but with major caveats. Its strength is quick ideation and generating a complete "song" with structure (intro, verse, chorus). For scoring, you often need *texture* and *mood* that evolves with a scene, not a traditional pop song format.
Here’s the real talk:
* **You'll fight the "song-ness":** Udio defaults to creating full musical pieces with drums, bass, and melodic hooks. Getting it to produce a simple, evolving ambient pad or a minimalist piano cue requires very precise prompting. Think "cinematic ambient textures, no percussion, no strong melody, slowly building tension" rather than "orchestral music".
* **Timing is a crapshoot:** You cannot reliably generate a piece that hits specific emotional beats at exact timestamps (e.g., a sting at 0:45, a swell at 1:22). You'll be generating many variations and cutting them up in your NLE.
* **The workflow is backwards:** Instead of "score to picture," you're generating a mood, then editing the picture or the track to fit. It's more of a sound library generator than a scoring tool.
My minimal approach suggestion:
1. Use Udio to generate 60-90 second mood pieces based on your scene's core emotion.
2. Import the stems (Udio provides them) into your editor.
3. Mute the drum track immediately (it's usually the most "song-like" element).
4. Slice, rearrange, and layer the remaining stems to fit your scene's rhythm.
Is it suitable for a complete newbie? Yes, but only if you're prepared for a collage-like workflow. It won't replace a composer or a dedicated scoring tool, but for zero-budget projects, it's a powerful way to get original textures without licensing headaches. Just don't expect it to read your mind or your timeline.
You've nailed the core limitation with the "song-ness" problem. It's a fundamental architectural mismatch - these models are trained on discrete tracks, not the continuous, non-repetitive sonic beds film scoring often requires.
I'd push back slightly on the timing issue being purely a crapshoot. While you can't get frame accuracy, you can engineer prompts for structural elements. Using terms like "a sudden dissonant cluster at the 55 second mark, followed by a decaying silence" can sometimes yield workable results, but it requires generating dozens of iterations. The latency and cost for that iterative process becomes prohibitive for a multi-scene film.
The real workflow hack I've found is to use Udio for generating *stems* or *motifs*, not finished cues. Generate a 30-second atmospheric loop, then stretch and layer it in a proper DAW. Treat it as a sample library, not a composer.
