Seedance vs Kling: the short answer
Choose Seedance 2.0 when you need to build a scene from several references, revise footage you already have, extend a clip you've made, use 4K, or bring two separate photos into one scene. Choose Kling 3.0 Pro when a character image needs to follow a supplied performance.
This is Protoface's blog, and Protoface offers both models.
Side by side
Both models create video from a written description and animate an image. The split appears when you need more than a prompt, whether that is a particular performance, several pieces of reference material, or footage that already exists.
On Protoface, Seedance 2.0 Text to Video exposes resolution and audio controls, while Kling 3.0 Pro Motion takes an image plus a reference video.

Clip length, resolution and aspect ratio
Seedance gives you 4 to 15 seconds and a resolution choice from 480p through 4K. Kling's Text to Video and Animate options run from 3 to 15 seconds, while Kling has no resolution setting. Seedance is my pick when the delivery requires 4K, because it is the only model here with that control.
Kling's three-second minimum suits a quick reaction or a very brief image animation. Seedance starts at four seconds, so if you need a three-second cut in 4K, neither model does it. Each generation tops out at 15 seconds. For a longer shot, Seedance Extend can append a further 4 to 15 seconds to a clip; Kling has no Extend mode.
Seedance's extra framing options are 4:3, 3:4, and 21:9. A campaign that calls for a 3:4 portrait crop or 21:9 can use Seedance. For common landscape, portrait, or square output, format doesn't decide it, so the available input should.
Both Animate modes accept an ending image, called a last frame in Seedance and an end frame in Kling. Use that control when the final composition must be fixed, such as a pack shot facing the camera. Seedance Animate also follows the source image's aspect ratio when that setting is left open.
Sound
Both models can generate sound, but Seedance can also accept reference audio with a new Text to Video scene. That makes it the better fit when a sound cue belongs with a product image, visual reference, or written scene direction.
Kling Text to Video and Animate can generate sound when you turn that setting on, at the higher with-sound rate. Motion keeps the source video's sound by default. For choreography with music already tied to the performance, that is a cleaner arrangement than rebuilding the movement and music as a new scene.
Seedance Edit gives you a separate choice for footage you have already filmed. It generates audio by default, but it can preserve the original track instead. Keep the original track when a spoken line or sound cue is part of the shot; use generated audio when the edit needs a new sound treatment.
Motion control and reference inputs
Choose Kling 3.0 Pro when the movement itself is the instruction. Motion takes the character from your image and the performance from your video, so you don't have to describe the dance in words.
If you upload someone else's photo or performance video, use only material you have the right to use and the person's consent to use. Motion can match the character's orientation to either the image or the video, and it defaults to the video. The image setting suits a still whose facing direction matters; the video setting suits a performance whose direction needs to lead.
Motion has no duration or aspect-ratio control of its own. When a set runtime or crop matters, use Text to Video. Use Motion when copying a performance matters more; it won't set either.
Seedance is the choice when the scene needs more than one kind of input. ByteDance's announcement describes Seedance 2.0 as accepting up to nine images, three video clips, and three audio clips. A product scene that needs an image, a short cutaway, and a sound cue has more room to come together there.
Choose the Seedance mode by what you have. Text to Video is for a new scene: its image, video, and audio files guide the generation, rather than being footage that the model changes or continues. It runs for 4 to 15 seconds and lets you choose the output resolution and crop before generating.
The distinction matters when a project has both reference footage and footage that needs work. Use Text to Video when a video clip guides a new scene alongside the prompt and other references. Use Edit when that source clip needs a change, or Extend when its next segment is the job. That choice also determines whether Seedance bills the video as a reference or as input footage.
A still that needs movement: use Animate. Add a last frame when the shot must end on a planned composition.
Footage that needs changing: use Edit. Describe the change; leaving aspect ratio open keeps your crop.
Footage that needs another beat: use Extend. Write the continuation, not the existing clip. A last frame can land it on a product view or end card.
Price per second on Protoface
Seedance is lowest at 480p. Kling's silent rate is below Seedance at 720p, 1080p, and 4K. Kling with sound sits above Seedance at 720p and below it at 1080p and 4K. Kling has no listed resolution setting, so those figures are not prices for equivalent output specifications.
All output rates below are in USD per output second. The 10-second column uses one common duration, and the minimum column shows the shortest output each model will bill.
Model and setting | Rate (USD per output second) | 10-second output | Minimum billed duration | Minimum output charge |
|---|---|---|---|---|
Seedance 2.0, 480p | $0.063 | $0.63 | 4 seconds | $0.26 |
Seedance 2.0, 720p | $0.135 | $1.35 | 4 seconds | $0.54 |
Seedance 2.0, 1080p | $0.333 | $3.33 | 4 seconds | $1.34 |
Seedance 2.0, 4K | $0.702 | $7.02 | 4 seconds | $2.81 |
Kling 3.0 Pro, silent | $0.106 | $1.06 | 3 seconds | $0.32 |
Kling 3.0 Pro, with sound | $0.159 | $1.59 | 3 seconds | $0.48 |
Seedance also charges for input video in Edit, Extend, and Text to Video with a reference video. Combined billed input video is capped at 15 seconds, so two eight-second reference clips are billed as 15 seconds, not 16. A Text to Video scene using only images and audio has no video-input charge.
Output setting | Input video price per second |
|---|---|
480p | $0.0387 |
720p | $0.0832 |
1080p | $0.207 |
4K | $0.4185 |
Seedance 2.0's full rates are on its model page; Protoface pricing gives an overview of other models. Edit, Extend, and Text to Video with a reference video add an input-video charge that a still-led scene doesn't have. Resolution and sound then set the output rate. Pick the settings before comparing rates.
For a Seedance job with video input, check two things before generating: the output resolution and the length of the video you are supplying. The output rate follows the output resolution. The input-video rate applies only to Edit, Extend, or Text to Video with a reference video, while images and audio alone do not add that input-video charge.
Which model fits which video
Dance and motion videos
Kling 3.0 Pro is my pick for dance, choreography, or an acted movement that must follow a particular reference. Its image-plus-video motion control setup keeps the character separate from the performance.
An illustrated character and a reference clip you have the right to use are a clean fit for Motion. Pick a reference clip with one person doing one clear move. Without a reference performance, describe the dance in Text to Video. Pick Seedance if the clip needs a reference image or audio, or 4K; Kling works for a plain written description when you want a three-second cut or generated sound. For a wider look at photo-dance tools beyond these two models, see Viggle AI alternatives.
Two people in one scene
Seedance 2.0 is my pick for bringing two separate people together. It accepts reference images, and the two photos in one hug video workflow names it for combining a photo of each person into one video. Kling Animate starts from one image, so it isn't the named route for a photo of each person.
Use photos you have the right to use and only of people who agreed to the video. Label the finished video as AI-generated when you post it.
Product and b-roll shots
If your product shot needs a reference image, a cutaway clip, and a sound cue together, start in Seedance.
Kling has a different strength for a short sequence with a known order. In Text to Video, start with the required prompt, then add the optional multi-shot list when the sequence needs separate beats. Animate uses exactly one of those two fields, so a multi-shot list replaces the single prompt there. A three-beat b-roll sequence could open on the product in its setting, move to hands using it, then end on a close-up. Give each beat its own action and camera direction. That works when the order matters more than combining several references into one shot; for several references in one scene, use Seedance.
Name the product, action, surface, and light, then say what must stay still. A good prompt ends with a line saying what must stay still, as the prompt examples guide shows.
For a pack shot built from one product image, Animate is the direct starting mode. Add a last frame if the final layout is already planned. For a scene that needs the product image alongside a cutaway or sound cue, start in Seedance Text to Video instead, because it accepts image, video, and audio references for the new scene.
If the footage is right but the surface or light is wrong, use Edit. If you need the next beat, use Extend. If you have only a still, start with Text to Video or Animate. If a mascot or character must follow one exact demonstration, choose Kling Motion.
Using both on the same credits
Protoface lets you switch models on the same credits, so a project doesn't need to force every shot through one model. A launch reel could use Kling Motion for a mascot dance, then Seedance for a product scene built from stills, an audio cue, and filmed cutaways.
That split is useful when the project has two different source materials. The performance shot can begin with Kling's image-and-video Motion setup, while the scene-building shot can begin with Seedance's reference inputs or editing modes.

Frequently asked questions
Is Seedance 2.0 better than Kling 3.0 Pro?
Seedance 2.0 is the better choice when a clip needs several reference types, editing or extension, a 4K option, or two separate photos in one scene. Kling 3.0 Pro is the better choice when the essential instruction is a supplied performance for a character to follow.
Which is cheaper, Seedance 2.0 or Kling 3.0 Pro?
Neither model is always cheaper: Seedance 2.0 at 480p has the lowest rate, at $0.063 per output second. Kling 3.0 Pro costs $0.106 silent or $0.159 with sound per output second; silent Kling is below Seedance at 720p, 1080p, and 4K, while Kling with sound sits above Seedance at 720p and below it at 1080p and 4K. Kling has no resolution setting, so these aren't equal-output comparisons.
Can I use Seedance and Kling with the same credits?
Yes. On Protoface, you can switch models whenever you like on the same credits. That works well when one project contains a performance-led shot and a separate scene that needs editing, extension, or several references.
Does Seedance generate sound?
Yes. Seedance 2.0 generates native audio and accepts a reference audio file alongside image and video references. That suits a new scene with a sound cue. Kling can also generate sound in Text to Video and Animate, while Motion can retain the original sound from its reference video.
