How Do I Store and Retrieve MiniMax H3 Video Outputs?

Overview

Treat the provider’s output URL as temporary, not permanent. When a MiniMax H3 job completes, it typically returns a link to the video, but those links can expire or be subject to a retention window. Confirm the provider’s retention policy, then copy finished outputs to your own storage so you own the asset rather than depending on a link that may vanish.

Build retrieval into your completion step. As soon as a job reaches a completed state, download the output and write it to your storage — object storage such as S3 or an equivalent — keyed to the task ID, user, and generation parameters so you can find it again. Record metadata alongside it: the prompt, model version, cost, and timestamp. That record makes reruns, audits, and support requests straightforward instead of guesswork. Where personal data or user content is involved, apply your own retention and deletion rules rather than inheriting only the provider’s.

Do not leave the only copy on the provider’s URL, and do not wait days to fetch it, since a retention window can close before you notice.

With outputs in your own storage, the rest of your product — playback, downloads, sharing, deletion — runs on infrastructure you control rather than a link whose lifetime you do not.
