Small timeline jobs for 100 clips into 20 ads cost $7.60 on Sume

Preparing 100 six-second clips and assembling them into 20 five-clip ads costs $7.60 in small Sume jobs, about 9 percent of the $82.60 total once you add the $75.00 of Wan 3.0 footage. The footage is 100 x 6 x $0.125 = $75.00. The post-production jobs are each a cent or two, so the question is whether they add up. They do, to a number worth knowing.

Per-job prices

From the catalog: video trim $0.02, video filter $0.02, audio detach $0.01, timeline audio concat/split $0.01, timeline compose $0.02, timeline render $0.10 per output minute.

Where to save

Trimming and filtering are per clip, so they are $4.00 of the $7.60. If you can prompt for the right length, the trim job goes away, and that is $2.00 per hundred clips. Detaching audio is only needed when the clip's own sound should not reach the final mix; for Wan clips mixed over music you may need all five steps or none, depending on your edit.

Render is per output minute, rounded up. Five 6-second clips make a 30-second ad, so each ad bills one minute. Combining two ads into one 60-second file would cut the render line from $0.20 to $0.10 for the pair.

Scaling to 1,000 clips

The small-job arithmetic is linear. One thousand clips into 200 ads cost $76.00 in small jobs (ten times the $7.60 above) and $750.00 in footage at 6 s x $0.125. The post-production share is the same 9.2 percent.

To lower it, remove steps rather than negotiate prices. Skipping the filter on clips that need no look change saves $0.02 per clip, or $20.00 per thousand. Skipping the trim by asking for the exact length saves another $20.00. Both together take the job to $36.00.

Do not remove a step you will need later. A missing detach on a clip with unwanted audio means a second pass over the finished ad, and a re-render costs $0.10 per ad plus the work.

Per ad

Each ad carries 5 x ($0.02 + $0.02 + $0.01) = $0.25 for clip prep, plus $0.01 concat, $0.02 compose and $0.10 render, which is $0.38. Twenty ads is $7.60. Add the footage at 5 x $0.75 = $3.75 and an ad is $4.13 all in.

Checking the total

Add the job counts to your batch record, since small jobs are easy to lose track of.

• Jobs per ad here: 5 trims, 5 filters, 5 detaches, 1 concat, 1 compose and 1 render, which is 18 jobs.
• Twenty ads is 360 jobs, so concurrency and polling matter more than price at this size.
• Use idempotency keys per clip and per step so a retry never doubles a $0.02 job.
