Seedance 2.5
Seedance 2.5 combines a 30-second boundary, higher media counts, and video-editing reference input in one strict scene contract. Automatic duration is not underestimated at the 5-second default; Kyeo preauthorizes against the 30-second maximum.
At a glance
What is this model like?
First/last-frame input and reference media are mutually exclusive, and a last frame cannot be submitted alone. Reference videos and audio clips must each be 2–30 seconds, with separate 30-second aggregate limits. True media formats and image/video geometry are verified before credits are reserved.

Selection guide
Use these decision points when choosing a model.
When a 15-second or 9 / 3 / 3 limit is too low, 2.5 provides a wider contract.
When -1 lets the model choose duration, Kyeo conservatively reserves for 30 seconds, which raises the required credit balance.
A higher limit does not mean every slot should be used. Fewer conflicting assets can reduce both cost and instruction ambiguity.

Credit usage
Without reference video, 480p, 720p, and 1080p cost 28, 63, and 114 credits per output second. With reference video, their rates are 17, 38, and 68.5 credits per second, multiplied by verified total input-video duration plus reserved output duration. Kyeo keeps the raw decimal total and rounds up only after multiplication; automatic duration is preauthorized against the 30-second output maximum, then settled against actual consumption.
Before batch generation, run an A/B test with the same assets across the current model and alternatives to validate quality and avoid wasting credits.

Seedance 2.0 Mini
Seedance 2.0 Mini combines text, first/last-frame, and multimodal-reference generation in one entry point. Reference video enters the pre-task pricing formula, so both media duration and output duration must be verified before task creation.
MiniMax H3
MiniMax H3 offers 768P and 2K output with text, first/last-frame, and image/video/audio reference scenes. Reference-video duration and every input image from image 6 onward affect pre-task authorization.
Wan 2.7 Video
Wan 2.7 supports text-to-video, first-frame or first-and-last-frame image-to-video, and video editing. It currently offers 720p and 1080p, so compare media requirements, duration, framing, and estimated credits together.
