What the difference looked like in our films
- Seedance 2.0 rendered episode 1 of The Fall of Kalak: 53 clips for $61, $1.15 a clip at our account price.
- Seedance 2.0 Mini rendered episodes 2–9 of the same film: 374 clips for $52, $0.14 a clip, roughly 8.3 times cheaper per clip. Mini also rendered The Wolf Mother (431 clips), Blood Sun: The Fall of Kratos and every episode of High Note.
- Seedance 2.0 Fast rendered The Emperor's Pleasure Court, Dragon Rising and BROODFALL (972 clips). At 16:9 it held character identity as well as Mini did at 9:16, and dialogue came through essentially word-perfect. About 1 in 15 Fast clips failed once and passed on retry.
- The cost of picking the wrong one: using Fast where Mini would have done cost us $101 extra across our first five series.
What to pick when
- Mini for long series, drafts and anything where volume matters more than the last bit of detail. Render the pilot on it too, so the look matches from episode one.
- Fast when Mini's output is not holding up for your look, especially widescreen work with detailed sets, at a moderate premium.
- Seedance 2.0 for 1080p, hero shots and short ads where each frame is on screen for a long time.
- Do not switch tiers mid-series unless you accept a visible change in look.
In Arc a 10-second 720p clip costs 94 credits on Mini, 226 on Fast and 751 on Seedance 2.0; at 1080p, Seedance 2.0 costs 1,689.
Where Katechon Arc fits
Arc offers all three tiers in the same project, shows the credit estimate before each clip, and lets you change the model in project settings for drafts or finals.
Arc does not offer Seedance 2.5 or other model families; if you need those, use a model API provider directly.
