6 hooks, 3 lengths, 18 vertical clips for Spark Ads: $23.28

Eighteen vertical test clips (six hooks, each cut at 6, 10 and 15 seconds) cost $23.28 on Wan 3.0 or $35.22 on Seedance 2.0 Mini at 720p on Sume. Adding one Timeline render per clip for the MP4 you post brings that to $25.08 and $37.02. The arithmetic is below, and every price comes from the catalog formula (provider list times 1.25, rounded up to the cent).

The price grid

Billable prices per clip at 720p, 9:16, as of 2026-10-08. A hook is one idea cut at three lengths, so one hook is the sum of three clips.

Wan 3.0 is priced per second and does not take an aspect-ratio price key, so the same price applies at 9:16. Seedance 2.0 Mini is priced per video token, and the 9:16 prices below come from the catalog.

Check the sums

Wan 3.0: 75 + 125 + 188 = 388 cents per hook, times 6 hooks = 2,328 cents = $23.28.

Seedance 2.0 Mini: 114 + 189 + 284 = 587 cents per hook, times 6 = 3,522 cents = $35.22.

Both models accept all three lengths. Wan 3.0 accepts 2 to 30 seconds, and the Mini row accepts 4 to 15 seconds, so 6, 10 and 15 s are inside both ranges. Seedance 2.0 Mini lists 9:16 among its aspect ratios, and so does Wan 3.0.

What TikTok asks of a Spark Ad file

The Spark Ads overview says Spark Ads use posts from organic TikTok accounts, so views, comments, shares, likes and follows gained while you boost the video are attributed to the organic post. The specification page lists Spark Ads (pull) video as .mp4 or .mov, with captions taken from the organic caption, at most 4 lines.

The overview page also says the video has no restriction on ratio, resolution, file type, bitrate or file size. A 15-second clip is far from any duration limit on either TikTok page.

• Spark Ads (pull) formats: .mp4 or .mov (TikTok specification page, read 2026-10-08).
• No ratio, resolution, file-type, bitrate or size restriction (TikTok Spark Ads overview, read 2026-10-08).
• Each Ads Manager account supports at most 10,000 Spark Ads (same page).

Finishing each clip

A raw model clip is not yet the post. Timeline 1.0 returns one MP4 at $0.10 per started output minute, and its default output is 1080x1920. Eighteen renders at $0.10 add $1.80: $23.28 + $1.80 = $25.08 on Wan, and $35.22 + $1.80 = $37.02 on the Mini.

If the six hooks share a voice-over or a music bed, build those once and reuse them. Music 1.0 is a fixed $0.125 per generation, so one bed shared by all eighteen renders adds 12.5 cents, not $2.25.

Before you post, probe one finished file with video inspect and confirm duration, dimensions and audio. Then post the six winners organically and authorize them as Spark Ads in TikTok's own flow. Sume does not do the authorization step.
