# Motion One vs Seedance

> Motion One vs the Seedance family: the free-tier, uncensored 720p engine against 1080p, seeded, 30-second premium engines that are SFW-only. When each is the right call.

Motion One is eroq's own engine: free-tier, 5 or 10 seconds at 720p, and the only video engine on eroq that renders mature scenes. Seedance is the premium family: 1080p, seeds, end frames, up to 30 seconds — and moderated upstream. The comparison is less "which is better" than "which is allowed to make your shot".

| Criterion | Motion One | Seedance (Lite · Pro · 2.5) |
| --- | --- | --- |
| Clip length | 5 or 10 s | 3–12 s · 4–30 s (2.5) |
| Resolution | 720p | up to 1080p |
| Content | Uncensored within the AUP | SFW only |
| Seed | No | Yes |
| First/last frame | No | Yes |
| Native aspect ratios | Prompt-steered | Yes |
| Price per 5 s | 100 cr | 60 (Lite) · 140 (Pro) · 180 (2.5) cr |
| Plan access | Every account | Hobby (Lite) · Creator (Pro, 2.5) |

## Verdict

- Mature fiction, or no plan yet: Motion One, no contest — it is the only engine that will render it.
- SFW work on a plan: Seedance Lite for drafts, Pro or 2.5 for keepers; sharper, longer, revisable.

## FAQ

### Why are the premium engines SFW-only?

Their providers moderate content upstream of eroq. Motion One runs on an uncensored deployment, which is why it is the mature-content engine.

### Is Motion One free?

It needs no plan — every account can reach it. It is not free to run, though: a 5-second clip costs 100 credits, so the 50 welcome credits do not cover a full clip. They are sized for chat, an image and a voice line.

### Can I start on Motion One and move to Seedance later?

Yes. One wallet pays for every engine, so a plan simply unlocks the others. The catch is content — work that Motion One renders may be refused by the moderated engines.

### Does Motion One take a seed or an end frame?

Neither. Both are Seedance features. On Motion One a re-render is always a fresh take, so batch several and keep the best rather than trying to reproduce one.

### What resolution does Motion One render?

720p, in 5 or 10-second clips. There is no upscaling step on eroq, so 1080p means moving to Seedance, Kling or Veo — all of which are SFW only.
