Model comparisons
Video Character Swap or MiniMax H3 Character Swap, tier by tier: matched prices, request fields, limits and the content policy measured on each.
Video Character Swap API recasts selected people throughout an existing clip, including their clothing and build. Analyse a 5–30 second MP4, choose the numbered previews, then attach 1–3 character photos to each selected person at 480p or 720p.
View model details →View sample outputs →MiniMax H3 Character Swap replaces one person in your clip with the character from an image and keeps the original performance, camera and scene, from 3 to 15 seconds at up to 1080p.

Start with the input you have, the result you want and your budget. These are the differences that affect that choice.
These tools produce different results. Choose the operation you need first; a lower price does not make one a substitute for the other.
Current price
A start price answers a different question than the one you have. These are the tiers both models publish, matched setting for setting, in US dollars per billed unit with no conversion step in between.
These two bill on different tiers, so there is no row to line up. Each one's own published tiers are listed here instead.
Video Character Swap: 480p $0.064 / output seconds · 720p $0.12 / output seconds
MiniMax H3 Character Swap: 480p $0.06 / output seconds · 540p $0.09 / output seconds · 768p $0.12 / output seconds · 1080p $0.24 / output seconds
About this comparison
Every row here is read from the JSON Schema the endpoint validates against, so it matches what the API will really accept rather than a feature list written by hand.

Do low-filter models allow every request?
Two separate facts sit behind these labels. The first is what we do, which is nothing: no platform content filter, and no maturity flag to set on a request. The second is what each model does on its own, and that is the only part that varies between these two.
Video Character Swap
This model declares no content filter. SpicyAPI forwards the request without adding a platform content scan; legal and consent duties remain with the customer.
MiniMax H3 Character Swap
This model declares no content filter. SpicyAPI forwards the request without adding a platform content scan; legal and consent duties remain with the customer.
Use these content labels to shortlist models, then open each model page for available examples and content-test details.
The label never changes your obligations. Age, consent, real-person likeness and the law where you operate stay with you, and SpicyAPI does not inspect each request.
Can I swap the model ID without changing the request body?
The task lifecycle is shared; the body is not. Each endpoint publishes its own JSON Schema and the API validates against that, so this is the list to reconcile before a switch.
How to choose
MiniMax H3 Character Swap supports clips up to 15 seconds.
MiniMax H3 Character Swap returns a soundtrack in the same file as the picture; the other returns picture only, so audio has to be added afterwards.
MiniMax H3 Character Swap supports a high-resolution option.
Compare
The model identifiers are spicyapi/character-swap-v1/video-edit and minimax/h3-character-swap/video-edit, and both go in the same field of the same request.
Both run the same way: submit the task, then poll it or take the callback. Queueing and retry logic carry over unchanged.
Both use the same submit-and-track flow, but their required inputs may differ. Check each model page before switching.
One key, one balance, one set of spend caps. Both bill to the same account in US dollars, and the per-key daily, monthly and lifetime limits apply to whichever one you call.
Questions developers ask
These tools produce different results. Choose the operation you need first; a lower price does not make one a substitute for the other. Prices may change; check the estimate shown for your actual settings before submitting.
Video Character Swap allows 180 minutes per task and MiniMax H3 Character Swap allows 60. Those are ceilings rather than typical times — most requests finish far sooner — but they are what your own client timeout has to survive.
