Veo 3.1 Fast vs Seedance 2.0

These two never price the same render: Veo 3.1 Fast sells clips of 4s, 6s and 8s and Seedance 2.0 sells 5s, 10s and 15s, so there is no like-for-like row to put them on and any straight price comparison would be comparing different products. They do both price 720p and 1080p, though, and a second of 720p is a second of 720p whichever model made it, so the comparison that does hold is credits per second at the same resolution: 720p is 30 credits a second on Veo 3.1 Fast against 28 on Seedance 2.0; 1080p is 30 credits a second on Veo 3.1 Fast against 63 on Seedance 2.0. Which one is the better rate depends on the resolution you deliver in: Veo 3.1 Fast at 1080p, Seedance 2.0 at 720p. Those are each model's best rate at that resolution, taken from the tables below.

Not at the same length. Veo 3.1 Fast sells 4s, 6s and 8s and Seedance 2.0 sells 5s, 10s and 15s, and there is no length both price, so a Veo 3.1 Fast render and a Seedance 2.0 render are never the same product. What they do share is resolution: both price 720p and 1080p. Per second of finished video that works out at 30 against 28 credits at 720p and 30 against 63 credits at 1080p. Multiply by the length you actually need and you have the real comparison.

Veo 3.1 Fast caps at 8s and prices 4s, 6s and 8s. Seedance 2.0 caps at 15s and prices 5s, 10s and 15s. Both are per-render limits, so a longer ad is several renders cut together rather than one long generation.

Veo 3.1 Fast is priced at 720p and 1080p, all at the same credit cost for a given length. Seedance 2.0 is priced at 720p, 1080p and 4K. Those are the tiers you can actually buy, not the tiers the vendors advertise.

Seedance 2.0 carries up to 9 reference images into one render and Veo 3.1 Fast carries one. That matters when a shot has to combine things you already have, a product, a hand, a background, in the same frame: with one image the rest has to be described in the prompt and re-rolled until it lands. The counts are read from the request each model is actually sent, not from a vendor spec sheet.

Both do. Neither Veo 3.1 Fast nor Seedance 2.0 will render from a text prompt alone, so you need a product shot or an avatar frame first.

The same way. Veo 3.1 Fast generates its audio in the same pass as the picture, so there is no separate voice step to run or pay for, and Seedance 2.0 works identically. Neither one needs a voice model bolted on afterwards.

No. Every plan is one credit balance that spends on any model we run, so the same subscription renders a Veo 3.1 Fast test at 120 credits and a Seedance 2.0 test at 140 and you compare them on your own footage. There is no per-model licence, and on a paid plan credits are the only thing that runs out rather than a render count.

One of them. Veo 3.1 Fast runs during the free 3-day trial, from 120 credits a render against a 250 credit per-render ceiling. Seedance 2.0 is not available on the trial and needs a paid plan. We would rather say so on this page than have the product refuse after you have signed up.

From the accounts the renders actually run on. Veo 3.1 Fast is dispatched to Replicate as google/veo-3.1-fast and Seedance 2.0 to BytePlus as undefined, both ours. The 6 priced tiers listed for Veo 3.1 Fast and the 9 priced tiers for Seedance 2.0 are read at build time from the same price table that debits your balance when a render finishes, and the capabilities come from the record the generator reads to build each request, so a reprice or a new tier rewrites this page instead of leaving a stale number on it. What you will not find is a quality or realism score for either one: we hold no benchmark that would make one honest.
