90-second Shorts ad: the feed plays 60 s; three Sume jobs priced

A 90-second vertical ad for YouTube Shorts is three 30-second Sume jobs and one Timeline render. On Wan 3.0 at 720p that costs $11.25 for generation plus $0.20 for two Timeline minutes, $11.45 in total. On Seedance 2.5 at 720p it is $52.22.

Google's Shorts ads page says video ads can be up to 3 minutes long, but only the first 60 seconds play in the Shorts feed. So the first 60 seconds of a 90-second ad have to carry the message.

What Google says about length

The Google Ads Help page on YouTube Shorts ads specifications gives these points: 9:16 vertical is recommended, with horizontal and square supported; video ads can be up to 3 minutes; the recommended length is under 60 seconds; in the Shorts feed only the first 60 seconds are shown; and an overlay at 50 seconds lets viewers watch the full ad on the YouTube watch page.

The page also gives campaign-specific ranges: Video Reach campaigns take 6 to 60 seconds; Video Action, App and Performance Max take 10 to 60 seconds; and 10 to 30 second vertical videos are recommended for action-oriented ads.

What that means for a 90-second cut

The page does not say how a campaign type enforces its range for a file longer than 60 seconds, so treat the listed range as the limit and test the upload.

• Seconds 0 to 50 are the part everyone sees in the feed before the overlay appears. Put the offer and the call to action there.
• Seconds 50 to 60 are still in the feed, with the overlay present.
• Seconds 60 to 90 only play on the watch page after a viewer taps through. Use them for detail, not for the message.
• Every campaign range listed above stops at 60 seconds. Check the objective of your campaign before you upload a 90-second file.

The job layout on Sume

Wan 3.0 and Seedance 2.5 take up to 30 seconds per job, so 90 seconds needs three. Run all three with aspect_ratio: "9:16", the same resolution and duration: 30, then join them in Timeline 1.0. Timeline bills $0.10 per started output minute, and 90 seconds is two minutes, so the join costs $0.20.

Generation prices are the published list times 1.25, rounded up to the cent per job.

Pacing the three clips

Because each job is independent, the join point is where continuity can break. Use the last frame of clip one as the first frame of clip two: Seedance 2.5 and Wan 3.0 both accept image-to-video input and an end frame. Plan the 50-second mark so that it lands inside clip two, which keeps the overlay from covering a hard cut.

Captions are priced as a standalone job at $0.20 for videos of up to 60 seconds, so a 90-second file does not fit that price. Caption each part or build the captions into the edit instead.

When to stop at 60

If the campaign objective is one of the listed types, whose ranges stop at 60 seconds, a 60-second ad needs two jobs, not three: $7.60 on Wan 3.0 at 720p including one Timeline minute. The extra 30 seconds of a 90-second ad cost $3.85 more, and only viewers who open the watch page see them.
