A 30-minute study-music video with one held image costs $4.51 on Sume: $1.50 for twelve Lyria tracks, $0.01 to join them and $3.00 for the render. Almost all of the cost is the render, which is billed at $0.10 per output minute.

Sume Music has no duration field, so ask for the length in each prompt, for example a 2.5-minute lofi track in a given key and tempo. Twelve tracks of 2.5 minutes make 30 minutes, though a model may not hit the length exactly, so check the total before you join them.

The steps and costs

StepRateCost
12 Lyria tracks$0.125 each$1.50
Join into one audio file$0.01 per job$0.01
Timeline render, 30 minutes$0.10 per minute$3.00
Total$4.51

Join, then render

Timeline audio concatenates up to 20 parts into one file of up to 1800 seconds, which is exactly 30 minutes. Then Timeline takes that file as the audio spine with duration_seconds set to 1800 and a single still in video[].

Before you pay, call POST /v1/timeline-1.0/plan. It is unbilled and tells you whether the request is valid and how it will render.

Keep the tracks varied

Twelve tracks from a similar prompt can sound alike. Change the tempo or an instrument in each brief. Listen to the joins; a hard cut between tracks is a choice you can fade out with the Timeline fade options.
