20-second product video: Omni caps at 10 s, Wan 3.0 does it in one

A 20-second product video is one Wan 3.0 job on Sume: $1.25 at 480p, $2.50 at 720p and $5.00 at 1080p. Gemini Omni Flash 1.1 stops at 10 seconds, so the same length is two clips and a Timeline join, which is $3.85 at 1080p and $2.60 at 720p.

Wan 3.0 accepts 2 to 30 seconds. If one continuous shot matters, Wan is the only one of the two that gives you 20.

Cost for 20 seconds

The Omni route adds one Timeline render, billed at $0.10 per output minute. The join also puts a cut in the middle of the film.

The trade

Omni is cheaper at 1080p, even with the join. Wan is simpler: one request, one file, no seam. The seam matters when the product is a single moving object, such as a watch turning or a bottle pour, because two independent 10-second clips will not continue each other's motion.

Omni can take the end of clip one as the start of clip two only if you pull a frame yourself and send it as the next first frame. The docs do not describe an automatic extension on Sume.

Going to 30 seconds

Wan 3.0 runs to 30 seconds in one job: $1.88 at 480p, $3.75 at 720p and $7.50 at 1080p. Use 480p at $0.0625 a second for a cheap composition test.

Omni cannot reach that length in one job. Three 10-second clips and a join come to $5.73 at 1080p, on the Timeline render of $0.10.

Which to pick

Choose Wan 3.0 for one continuous 15 to 30 second take, or when you want to supply an audio or video reference. Choose Omni for clips of 10 seconds or less, for native sound, or for 4K.

Sume does not judge which looks better. Run the same product on both at 720p and compare before you spend at 1080p.
