Creatify Aurora 2k credits per second: 2.8, audio up to 14.375 s

Creatify prices Aurora 2.0 by resolution: 0.4 credits per second at 480p, 0.7 at 720p (the default), 1.4 at 1080p and 2.8 at 2k. The API reference adds that 2k is only for audio up to 14.375 seconds. Sume does not have a resolution ladder on Avatar Video: the docs say resolution is currently 720p.

Creatify numbers are from its billing and API reference pages, read 2026-10-01. Sume facts are from Avatar videos.

What does each Aurora 2.0 resolution cost?

Multiply the rate by the audio seconds; Creatify bills Aurora 2.0 in 1-second increments. A 10 second clip at 2k is 28 credits and at 720p is 7 credits, using the rates in the table.

What changes if my audio is longer than 14.375 seconds?

Per the API reference, 2k is not available for that audio, so the top choice becomes 1080p. The resolution setting only applies to aurora_v2; it has no effect on the v1 models.

What does Sume offer instead?

Avatar Video takes aspect_ratio (1:1, 3:4, 9:16, 4:3, 16:9) and a named quality of standard, plus (default) or max, with resolution fixed at 720p. The Fabric still-plus-audio endpoint lists 480p and 720p. Quality is a tier you pick, not a multiplier on seconds. For aspect ratios, see Avatar video aspect ratios.

How do I know the cost before I run?

The MCP docs say an optional dry_run preflights cost. Use it before a long render instead of doing the credit arithmetic by hand. Either way, an unfunded run returns 402 insufficient_credits.
