Short answer: choose Seedance 2 when the job depends on reference images, reference video, reference audio, or first-and-last-frame planning. Choose Kling 3.0 when you want a simpler text-to-video or single-start-image workflow with an explicit Standard or Pro mode and optional generated sound. This is an editorial workflow recommendation based on the controls currently exposed on AI Image Video—not a claim that one model has better visual quality.
Both models are available in the text-to-video workspace and image-to-video workspace, so the most reliable choice is to compare them with the same brief and judge the outputs against your own acceptance criteria.
Seedance 2 vs Kling 3 at a glance
| Decision factor | Seedance 2 | Kling 3.0 |
|---|---|---|
| Current platform workflows | Text to video, image to video, reference to video | Text to video, image to video |
| Supported media inputs in the platform registry | Text, image, video, audio | Text and one starting image |
| Current output choices | 480p or 720p; 4–15 seconds | Standard 720p or Pro 1080p; 3–15 seconds |
| Frame/reference controls | First frame, last frame, reference images, reference video, reference audio | Optional first image; image input determines framing unless an accepted ratio is supplied |
| Other exposed controls | Generated audio, web search, seven aspect-ratio choices including Adaptive | Optional generated sound; 16:9, 9:16, or 1:1 for text-to-video |
| Current credit unit | Per billable second | Per output second |
| Best workflow fit (editorial) | A reference-led brief with several assets or endpoint framing | A direct prompt/start-image brief with a clear resolution tier |
The important difference is the input plan
Seedance 2 is the broader asset-orchestration workflow. A request can begin with text alone, a first frame, first and last frames, or a reference package containing images, video, and audio. The current integration prevents first/last frames from being mixed with reference media, so decide which branch you need before uploading assets. Its current output controls allow 4–15 seconds, 480p or 720p, and 1:1, 4:3, 3:4, 16:9, 9:16, 21:9, or Adaptive.
Kling 3.0 is narrower but easier to budget from a brief. Text-to-video accepts a prompt and one of three aspect ratios. Image-to-video accepts one starting image. The platform exposes a Standard 720p route and a Pro 1080p route, each with optional sound, for 3–15-second output. The current stable integration is single-shot; multi-shot authoring is not exposed.
That makes the first decision practical: if identity, motion, sound, or an ending composition must be communicated through supplied media, Seedance has the relevant controls. If the deliverable can be expressed as a prompt plus at most one starting still, Kling has fewer variables to manage.
Credit comparison on AI Image Video
These are platform credits, not competitor subscription prices. Rates can change, so confirm the live estimate in the workspace before generating.
Seedance 2 uses a per-billable-second schedule:
- Without reference video: 29 credits per output second at 480p or 62 at 720p.
- With reference video: 18 credits per billable second at 480p or 38 at 720p.
- When reference video is used, billable time includes verified reference-video time plus output time.
For example, a 5-second 480p output without reference video is 145 credits at the current static rate. Do not apply that multiplication to a reference-video job without also accounting for its input duration.
Kling 3.0 uses credits per output second:
- Standard: 25 credits/second without sound or 35 with sound.
- Pro: 30 credits/second without sound or 50 with sound.
A 5-second silent Standard output is therefore 125 credits; the same duration in silent Pro is 150. These examples explain the unit, not a promise about future rates or output quality.
Who should choose Seedance 2?
Seedance 2 is the more suitable editorial choice when:
- A defined opening and closing frame matter to the cut.
- Several visual references need to guide the same generation.
- A source video or audio reference is part of the creative brief.
- An ultra-wide 21:9, 4:3, 3:4, or Adaptive frame is required.
- The team is prepared to document exactly which references are necessary.
Start with image to video when a supplied opening still is the primary constraint. Use text to video when no visual asset should anchor composition.
Who should choose Kling 3.0?
Kling 3.0 is the more suitable editorial choice when:
- The brief is text-only or has a single approved start image.
- 720p Standard versus 1080p Pro is a useful production decision.
- Sound should be switched on or off as a visible budget choice.
- The target is a common landscape, portrait, or square format.
- A single-shot request is enough for the intended clip.
The simpler input contract can also make approvals clearer: prompt, starting image if any, duration, mode, sound, and ratio are the core variables.
A fair same-input evaluation plan
Do not compare unrelated prompts. Run a controlled review instead:
- Write one 60–100-word brief with subject, action, setting, lighting, camera direction, duration, and aspect ratio.
- Choose a shared supported setup: 720p, 5 seconds, 16:9, and generated audio either off for both or on for both.
- For text-to-video, paste the identical prompt into both models. For image-to-video, upload the same start image and keep the motion instruction unchanged.
- Generate the same number of candidates. Record each model, mode, resolution, duration, audio setting, and credit estimate before submitting.
- Score only criteria tied to the deliverable: subject continuity, requested action, framing, camera path, unwanted objects, usable beginning/end frames, and audio relevance if enabled.
- Repeat only the failed criterion with one prompt change. Changing several instructions at once makes the result hard to interpret.
A suitable test prompt is: “Five-second 16:9 product shot of a cobalt travel mug on a light stone counter. Slow clockwise camera arc, soft morning window light, one continuous shot, no text, no extra objects, mug remains centered.” Replace the subject with your own asset; do not add Seedance-only references during the baseline round.
Limitations to consider
- This comparison describes the current AI Image Video implementation, not every capability a model provider may offer elsewhere.
- No live benchmark, visual-quality ranking, or generation-speed measurement is claimed here.
- Seedance reference-video credits use billable input plus output time; a headline rate alone is not a full quote.
- Kling Standard and Pro have different resolution and sound rates, so compare equivalent settings.
- Generated video remains nondeterministic. One output should not be treated as a general ranking.
- Rights, consent, brand rules, and final quality control remain the creator’s responsibility.

FAQs
Is Seedance 2 better than Kling 3?
There is no repo-backed universal quality winner. Seedance 2 has more reference-media controls in the current platform; Kling 3.0 offers a focused single-shot workflow with Standard and Pro modes. Choose by required inputs, settings, and your own same-brief review.
Do both support text-to-video and image-to-video?
Yes. Both are selectable for those two workflows. Seedance 2 additionally has a reference-to-video operation in the platform registry.
Which supports 1080p on the platform?
Kling 3.0 Pro is exposed as 1080p. The current Seedance 2 site variants in this comparison are 480p and 720p.
Can both generate audio?
The current registry lists audio generation for both. Kling exposes different per-second rates depending on whether sound is enabled.
Where can I compare them?
Open Text to Video for a prompt-only comparison or Image to Video for a shared starting-frame comparison. Review the displayed credit estimate and settings before submitting each generation.
