Seedance 1.5 Pro

Seedance 1.5 Pro / Capabilities — Seedance 1.5 Pro on Kyeo AI accepts text alone or up to two images and exposes 480p/720p/1080p, 4–12 seconds, generated audio, six ratios, and a fixed-lens switch. The 7–180-credit cost follows the selected combination; the Pro name and higher credit cost do not prove image quality, stability, or publication readiness.

Selection guide

Use these decision points when choosing a model.

1
Decide whether the request uses images first

Decide whether the request uses images first — Submit the same prompt with one and then two images to inspect how the second affects subject, composition, and motion.

2
Treat audio as a separate variable

Treat audio as a separate variable — Enabling audio doubles the credits for every resolution and duration combination. Hold the prompt, images, resolution, duration, and camera control fixed; change only `generate_audio`, then compare audiovisual sync, output differences, and manual correction effort.

3
Begin with the lowest-cost combination

Begin with the lowest-cost combination — Start at 480p, 4 seconds, no audio, and dynamic camera. After confirming the workflow and content, change only one of resolution, duration, audio, or second-image input, then recheck the credits.

Practical usage insights

Practical guidance based on public sources, current on-site limits, and representative tasks.

Twenty-eight credits is only the default

Seedance 1.5 Pro / Twenty-eight credits is only the default — The default 720p, 8-second, silent request costs 28 credits. Every resolution, duration, or audio change selects another lookup entry, so 28 is not a universal request price.

Parameter names are not test results

Seedance 1.5 Pro / Parameter names are not test results — 1080p, Pro, fixed lens, and generated audio describe the request.

Capabilities

Text-only or zero-to-two-image input

Text-only or zero-to-two-image input — Seedance 1.5 Pro on Kyeo AI accepts text alone or up to two images and exposes 480p/720p/1080p, 4–12 seconds, generated audio, six ratios, and a fixed-lens switch. The 7–180-credit cost follows the selected combination; the Pro name and higher credit cost do not prove image quality, stability, or publication readiness.

Eighteen priced parameter combinations

Eighteen priced parameter combinations — Kyeo AI uses a resolution-duration-audio lookup: silent requests cost 7–90 credits, and enabling audio exactly doubles the matched configuration for a maximum of 180 credits.

Ratio and lens-control boundaries

Ratio and lens-control boundaries — Dynamic and fixed camera behavior can be selected directly.

Use cases

A text-only shot test

A text-only shot test — Hold ratio, resolution, duration, and audio state constant, then compare the shot, movement, rendered text, and sound against observable requirements.

A one-image versus two-image test

A one-image versus two-image test — Submit the same prompt with one and then two images to inspect how the second affects subject, composition, and motion.

A generated-audio comparison

A generated-audio comparison — Run identical video settings with audio off and on, then review sound content, sync, output usability, and the doubled credit cost.

Prompt tips

Separate framing, subject, action, and sound

Separate framing, subject, action, and sound — Write framing and camera behavior first, then subject action, environmental change, dialogue, or sound. Replace labels such as cinematic or perfectly consistent with observable conditions.

Prepare the target aspect ratio before upload

Prepare the target aspect ratio before upload — Write framing and camera behavior first, then subject action, environmental change, dialogue, or sound. Replace labels such as cinematic or perfectly consistent with observable conditions.

Describe subject motion even with a fixed lens

Describe subject motion even with a fixed lens — Enabling `fixed_lens` limits camera movement; it does not define how people, objects, or the background move. Keep those actions explicit in the prompt.

Why choose it

Text-only or zero-to-two-image input — One workflow accepts text alone or up to two images.
Resolution — Offers 480p/720p/1080p and explicit 4–12-second choices.
Generate audio — Generated-audio cost is known for every resolution-duration combination before submission.
Lock camera — Dynamic and fixed camera behavior can be selected directly.

What to know first

Prompt length — 3–2,500 characters
Upload limit — 0–2 JPEG/PNG/WebP images, up to 10 MB each
Credit cost / Generate audio — Kyeo AI uses a resolution-duration-audio lookup: silent requests cost 7–90 credits, and enabling audio exactly doubles the matched configuration for a maximum of 180 credits.
Seedance 1.5 Pro — Model and page options can evolve; periodically recheck quality and credits with fixed samples for long-lived workflows.

Seedance 2.0

Seedance 2.0 / Capabilities — Text accepts no media; frames requires a first frame and allows a last frame; reference requires a prompt and at least one image, video, or audio reference. Reference media cannot be sent with endpoint-frame fields. Seedance 2.0 supports three mutually exclusive text, frame, and multimodal-reference scenes. The current callable output set is 720p, 1080p, and 4K for 4–15 seconds; video-reference requests are available only at 1080p or 4K because those are the current priced combinations. 164–3,840 credits per request

Kling 2.6

Kling 2.6 is a two-workflow video service on Kyeo: text requests use text-to-video, while requests with an image use single-image animation. Both routes offer 5/10 seconds and a `sound` toggle; text generation also provides three aspect ratios. The four Kyeo credit tiers are 55, 110, 110, and 220.
