Salon service menu reel: six stills and a music bed for $0.83

A 24-second reel for a salon menu, with six service cards, one generated music track and one Timeline render, costs $0.825 on Sume: $0.60 for six images at 1K, $0.125 for the music and $0.10 for the render. No video model is involved, because Timeline accepts stills as static holds.

The bill

Music Router charges a flat price per generation, whatever the model. Timeline 1.0 charges per rounded-up output minute.

The render

The music file is the audio spine. Ask for the length in the prompt, because Music Router rejects a duration field, and declare an audio.duration_seconds that is no longer than the file you got. Each card is a video[] slot of 4 seconds.

slots = []
for i in range(6):
    slot = {"source_url": f"https://media.sume.com/artifacts/artf_demo/card{i}.png",
            "start": i * 4, "duration": 4, "fit": "cover"}
    if i:
        slot["transition"] = {"type": "fade", "duration": 0.25}
    slots.append(slot)

body = {
    "audio": {"url": "https://media.sume.com/artifacts/artf_demo/bed.mp3",
              "duration_seconds": 24},
    "video": slots,
    "output": {"width": 1080, "height": 1920, "fps": 30},
}

Limits and gotchas

• Stills ignore motion and are reported as motion_ignored; that is a warning, not a failure.
• Put prices on the card images only if you check each one: generated text can be wrong.
• Use the free POST /v1/timeline-1.0/plan to confirm the cost before rendering.
• An mp3 spine adds encoder padding at joins; keep wav if you will concatenate.
