10 AI videos a week with one retake in four: real monthly cost

Ten 15-second Wan 3.0 clips a week cost $75.20 over four weeks at 720p on Sume, and $94.00 if one video in four is generated a second time. Retakes are billed like any other job, so the honest budget is the base cost times your retake rate plus one. The retake rates below are scenarios, not measurements.

Four scenarios

A 15-second Wan 3.0 clip at 720p is $1.88 after rounding up to the cent. Forty videos in four weeks, plus retakes as extra clips.

Where the plan flips

At 0, 25 and 50 percent retakes, Pro is cheaper than Startup because usage stays under $120. At 100 percent, usage is $150.40 and Startup's $140 allowance makes it $130.40 against Pro's $150.40. Scale does not pay off in any of these rows.

So the plan threshold in your own workflow is the point at which retakes push monthly usage past $120. Included usage figures come from Sume's plan catalog; the Billing and subscription page in the dashboard shows what is left on your workspace.

Measure your own rate

Track keepers against generations for two weeks before choosing a plan. A retake rate you can measure is better than one assumed here. Cheaper resolutions are one lever: testing at 480p, at $0.94 a clip, costs a fraction of 720p, so you can pick prompts at 480p and regenerate the final at 720p. See cost per finished minute with regeneration overhead and the weekly product-drop budget.

One more habit helps: keep a simple tally of generations and keepers per week. Retake rates differ a lot by prompt style, so a team that writes the shot as a short, concrete description may need far fewer retakes than one that leaves the model to improvise. The figure that matters is the number of generated seconds, not the number of videos, and Sume bills only generated seconds, rounded up per job.
