## Which one, for what

### HyperFrames (E)

Good for: HyperFrames turns HTML compositions into videos through a local CLI and preview studio.

Also in its favour:
- No key needed to call it

Watch for: Hosted MCP remains beta

### Seedance on BytePlus ModelArk (C)

Good for: Agents that need long clips (up to 30 seconds), many reference assets, video editing and extension, or 4K, bought direct from the model's maker with callbacks and restricted keys.

Ahead on:
- Reliability, 36 against 30
- Agent ergonomics, 85 against 60
- Security & auth, 79 against 20
- Maintenance & community, 75 against 50
- Transparency & trust, 63 against 28

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No status page was found on byteplus.com, the docs or the trust centre, and no SLA was found that names ModelArk inference

## Verdicts

**HyperFrames.** Local CLI with editable HTML project files. Hosted MCP remains beta.

**Seedance on BytePlus ModelArk.** The video task API documents limits, error codes and per-model parameters in detail, with callbacks, a filterable task list and API keys restrictable by model and IP address. No status page, OpenAPI file or free video quota was found, the newest models need a USD 30 balance, and BytePlus model services are not sold in the United States.

## Before you call either

### HyperFrames

1. Use the local CLI when project access and repeatable rendering matter.
2. Preview the composition and check assets before rendering.
3. Confirm account eligibility and credit cost before using the hosted beta.

### Seedance on BytePlus ModelArk

1. POST to `/api/v3/contents/generations/tasks` on ark.ap-southeast.bytepluses.com, then poll GET `/contents/generations/tasks/{id}` or pass `callback_url`. Callbacks need an answer within 5 seconds
2. Download the result at once. Video URLs last 24 hours, task records 7 days, and a Seedance 2.5 URL allows 100 downloads
3. Pass `resolution`, `ratio` and `duration` in the request body. Parameters appended to the prompt as `--rs` or `--dur` are weakly validated and may be ignored
4. On Seedance 2.5 set `omni_reference_task_type` to `edit` or `extend` so constraint errors arrive at submission. With `auto` they arrive after the task leaves the queue
5. Do not send reference images or video with real human faces to Seedance 2.5 or 2.0. Only a queued task can be cancelled with DELETE
