The Toolchain That Makes It Possible
The core workflow is model-chaining: you use one AI tool per production layer rather than expecting a single model to handle everything. A language model (Claude or GPT-class) writes the concept, lyrics, and shot list. An image or video diffusion model - like Runway Gen-3, Kling, or Pika - renders the frames. A music generation model (Suno or Udio) handles the audio track. A simple editor like CapCut or DaVinci Resolve stitches it together.
Each layer has gotten cheap enough that the total sits under £100 if you're deliberate about it.
The expensive variable is video generation: most platforms charge per second of rendered output, and quality settings matter. A 3-minute video at 720p with one revision pass across the whole piece is roughly where the budget gets tight - not impossible, but you can't be careless about retakes.
Real Example
Here's a rough budget breakdown for a 3-minute track with a narrative visual style:
Lyrics + concept (Claude/GPT via API): ~$0.10
Music generation (Suno, 10 attempts): ~$8.00
Image/video frames (Runway Gen-3, 90s): ~$55.00
Upscaling + cleanup (Topaz or similar): ~$12.00
Stock SFX + minor assets: ~$10.00
Total: ~$85.10
The workflow that keeps costs down:
- Write a tight shot list (20-30 described scenes) before touching any video tool
- Generate stills first, approve them, then animate only the approved frames
- Use 4-second clips instead of 8-second - half the cost, same cut rhythm
- Reserve the upscaler for hero shots only, not every frame
The model comparison angle (Claude vs. GPT for the creative direction step) matters less than people expect. Both produce usable shot lists. What separates outputs is prompt specificity - a vague aesthetic brief gives vague frames regardless of which model you use for the text layer.
Key Takeaways
- AI music video production is genuinely viable under £100 today, but requires deliberate resource allocation across the toolchain - video generation is where budgets blow out
- Model-chaining (separate tools per production layer) outperforms any single all-in-one tool for quality at this price point
- The creative direction prompt is the highest-leverage input: a detailed shot list with lighting, color, and mood descriptions cuts revision costs more than any model upgrade
The real bottleneck in this workflow isn't the AI models - it's the shot list quality before you generate anything. Have you found a prompting pattern for video generation that consistently reduces your retake rate?
