25-day Black Friday countdown series: 6-second clips cost $21.52

A 25-day Black Friday countdown made of 6-second Gemini Omni Flash 1.1 clips at 720p, each with a 120-character voiceover and a one-minute timeline render, costs $21.39 for the episodes plus $0.125 for one shared Lyria music bed, $21.52 in total on Sume. With the 5.5% platform fee from Sume's pricing policy the all-in figure is $22.70, or about $0.91 per day.

Each daily episode is three line items: the clip ({u(omni6)}), the voiceover ({u(tts)}) and the timeline render ({u(tl)}, because timeline bills per started output minute). The music bed is a flat generation charge, so one bed reused across 25 episodes costs the same as one.

One episode, itemised

The arithmetic

Clip: Omni Flash 720p lists $0.10 per second at provider level, times 1.25 is $0.125 per second, so 6 seconds is $0.75. Voice: 120 characters x $0.0000475 = $0.0057. Timeline: the public rate is $0.10 per ceil(output minute), so a 6-second render is billed as one minute. Per episode: $0.75 + $0.0057 + $0.10 = $0.8557. For 25 episodes: 25 x $0.8557 = $21.39. Add the bed: $21.39 + $0.125 = $21.52 (rounded from $21.5175).

The music bed is a fixed $0.125 for each accepted Music 1.0 generation and does not change with prompt length. If you generate a fresh bed per episode instead, the music line becomes 25 x $0.125 = $3.13, lifting the total to $24.52.

Steps

• Write all 25 hooks and 120-character VO lines in one pass so you can count characters before you pay.
• Submit each clip on POST /v1/videos with model: "gemini-omni-flash-1.1", duration: 6, resolution: "720p"; durations run 3 to 10 seconds and audio is always on.
• Generate the bed once on Music and reuse the file in every timeline job.
• Join clip, voice and bed in a timeline render per day.

If you want more per day

The series scales by clip length. At 10 seconds, the longest Omni clip, each episode's clip is 10 x $0.125 = $1.25, so an episode is $1.25 + $0.0057 + $0.10 = $1.36 and 25 of them cost $33.89 plus the bed. At 3 seconds, the shortest, the clip is $0.375 and the series is $12.02 plus the bed.

Resolution scales it too: 1080p is $0.1875 per second, so a 6-second clip is $1.125 and the series is about $30.77. Drop to 360p, $0.0375 per second, and a 6-second clip is $0.225, bringing the series to $8.27 plus the bed. Choose the resolution of the post, not of the screen it is edited on.

Whatever you choose, multiply the total by 1.055 to include the platform fee from Sume's pricing policy.

What Sume does not do

Sume does not give a series discount, does not schedule posting: it produces files, and you or an automation decide when each goes out. Omni Flash is limited to 16:9 and 9:16, so vertical Black Friday ads use 9:16.
