Jimeng

Jimeng is ByteDance’s video generation service. On Crazyrouter, the recommended public contract is the /jimeng/* family. We do not expose the upstream Action + Version form as the primary customer-facing API.

​
Currently Verified Scope

  • POST /jimeng/submit/videos is verified for jimeng-video-3.0 text-to-video
  • single-image input and single-image recamera are verified
  • the currently stable positive-sample mainline is concentrated on 1080P
  • 720P / recamera is still a ch119 carrier-level follow-up and is not being expanded into the current public hard contract
  • query results prefer Crazyrouter archived media URLs such as https://media.crazyrouter.com/...
  • the expired re-probe path is closed, but naturally expired samples are still a passive background tail item and do not block the mainline contract

The current public docs only commit to single-image input and single-image recamera. Do not document image_urls as a public multi-reference hard contract, and do not recommend frames as a public parameter. Unsupported frames values may be accepted at submit time and then fail later at the upstream pipeline stage.
The public doc is intentionally constrained to the verified stable scope: jimeng-video-3.0 + text-to-video / single-image input / single-image recamera. Whether 720P / recamera is expanded later depends on carrier-level sample follow-up rather than additional passthrough code.
