Creatify Aurora 2.0 max audio length: 59.7 s, and how to split

Creatify's API reference says aurora_v2 (Aurora 2.0) takes up to 59.7 seconds of audio, while the endpoint's general audio field says 5 minutes max (the page does not say which model that figure belongs to, so do not assume it holds for Aurora 2.0). If your clip is longer than 59.7 seconds, split it before you call Aurora 2.0.

On Sume, an Avatar Video job accepts a script whose estimated duration is 4-60 seconds inclusive; longer scripts are split into multiple jobs. Vendor facts below are from Creatify's page read 2026-10-01; Sume facts are from Avatar videos.

What are the audio limits side by side?

Why is 59.7 different from 60?

The two numbers measure different things. Creatify's 59.7 is the longest audio file Aurora 2.0 accepts. Sume's 4-60 window is checked against the duration Sume estimates for the target video, and it applies to a script or a multi-scene video_inputs plan. A 59.7 second voice-over fits both, but a 60 second one fits only Sume's window.

How do I split a longer script?

Cut at sentence or scene boundaries so each part reads as 4-60 seconds, then submit one job per part with the same avatar_handle. Sume's docs say to split longer scripts into multiple jobs; send each job with its own Idempotency-Key, since a key identifies one exact request. You can join the finished clips afterwards; see assemble long-form video with the Timeline API.

Can a request inside the window still fail?

Yes. The OpenAPI description for video_inputs says requests within the duration window can still fail with public_reason content_policy_rejected when a provider rejects generated clip content. Length is a precondition, not a guarantee. If the wallet cannot fund a run you get 402 insufficient_credits instead; see Errors and credits.
