Instagram Reel length buckets: what 3, 15, 60 and 180 seconds cost

A 15-second Reel made from AI clips costs about $1.88 on Sume at 720p, a 60-second Reel about $7.50, and a 180-second Reel about $22.50, using Gemini Omni Flash 1.1 at its catalog rate. A 3-second Reel costs $0.38. The price scales with seconds, not with the length bucket, so the bucket only decides how many jobs you queue.

Instagram's own Reels guide (read 2026-10-05) says a Reel can run "anywhere from 3 seconds to 3 minutes" and splits that range into three tiers: 3 to 15 seconds for quick transitions and trends, 15 to 60 seconds for tutorials and day-in-the-life content, and 60 seconds to 3 minutes for longer storytelling. Planning a content calendar by tier is easy. Budgeting it needs a per-second price and a rule for rounding.

The rate and the rounding rule

The Sume video catalog lists gemini-omni-flash-1.1 at a provider list price of $0.10 per second at 720p. Sume bills list price times 1.25, so one second costs $0.125. Each row of the catalog carries its own billable_formula, and the catalog is the source of truth: read GET /v1/videos/models before you commit a budget, because rates change.

This model accepts 3 to 10 seconds per job. A bucket longer than 10 seconds therefore needs several jobs. Each job is rounded up to the cent on its own, which is why splitting a 15-second Reel as 10 + 5 seconds ($1.25 + $0.63 = $1.88) is not the same as multiplying 15 by 0.125 ($1.875). The rounding is small, but it adds up over a batch.

Cost by tier

The table prices one example length in each tier, cutting every length into the fewest 10-second jobs. The last column adds one standalone caption job at $0.20, which Sume charges for a clip of up to 60 seconds.

What the numbers say about each tier

The first tier is the cheap place to test. A 3-second Reel costs less than a coffee, and a 15-second one is under $2, so you can render three takes of a hook for about $5.64 at the 15-second length (3 x $1.88) and keep the best one. The 60-second tier is where a single generation mistake starts to hurt: one failed 10-second shot is $1.25, and you may need to re-run it.

The 180-second tier is the one to plan most carefully. Eighteen jobs is a lot of queue, and every extra minute of runtime is a minute you have to fill with something worth watching. If your story fits in 60 seconds, the price difference is $15.00 ($22.50 against $7.50).

• Test the hook at the 3-15 second tier first. It is the lowest-cost place to find out whether the first frame works.
• Use longer-per-job rows when your tier is long. Seedance 2.5 and Wan 3.0 accept up to 30 seconds per job in the Video Router table, so a 180-second Reel needs 6 jobs instead of 18.
• Add captions after the cut is final. A caption job reads the finished clip, so burning before an edit would waste the $0.20.

A short checklist before you queue the batch

Read the catalog row for the model you picked and confirm its duration range and rate. Split the length into jobs that fit that range. Price each job separately and round up to the cent. Then price the join and the captions. The Timeline 1.0 render bills $0.10 per output minute, rounded up, and the video captions job is $0.20 for a clip of up to 60 seconds.

The rule of thumb is simple. The bucket is a creative choice. The cost is seconds times the rate, plus cent rounding on every job, plus one caption job per finished clip.
