Seedance 2.0 vs Kling O3 vs Kling 3.0: Specs

All three make video in Spicy Studio's Video Lab, but each starts from a different place.

Pick Kling 3.0 when your first frame is final and you want one clean 5- or 10-second shot in 16:9, 9:16 or 1:1, up to 1080p.

Pick Kling Omni O3 when one clip has to play several actions in order, each with its own prompt, or needs a length between 3 and 15 seconds.

Pick Seedance 2.0 when you have no image yet, when reference images, video or audio should steer the clip, or when you want the cheapest drafts. Past 15 seconds, the newer Seedance 2.5 takes over (below).

Spicy Studio wrote it and offers all three models, so read it as a guide to our own Video Lab, not an independent review. It compares settings and credit prices as of October 2026 and doesn't score output quality; the test at the end lets you judge that yourself.

Kling 3.0: a start frame is required (JPEG or PNG, up to 10 MB, at least 300 px); an end frame and a prompt are optional.

Kling Omni O3: also image-to-video: a first frame, an optional last frame, and either one prompt or a chain of segment prompts.

Seedance 2.0: the only one of the three that works from a text prompt alone. It also takes a first and/or last frame, or references instead: up to 7 images, a 2–15 second video and up to 15 seconds of WAV or MP3 audio, which needs a reference image or video beside it. Frames and references don't mix: once a first or last frame is set, the references aren't used.

Neither Kling model accepts reference images, video or audio.

Length: Kling 3.0 makes exactly 5 or 10 seconds, Kling Omni O3 any whole number from 3 to 15, and Seedance 2.0 anything from 5 to 15.

Resolution: Kling 3.0 renders 720p on Standard and 1080p on Pro. Seedance 2.0 offers 480p or 720p. Kling Omni O3 has Standard and Premium tiers rather than named resolutions.

Aspect ratio: Kling 3.0 offers 16:9, 9:16 and 1:1; O3 copies the first frame's shape; Seedance 2.0 adds 4:3, 3:4, 21:9 and adaptive to Kling's three.

Camera: only Seedance 2.0 has a Camera Fixed switch for locked-off shots.

Sound: all three can generate audio, off by default. It multiplies Kling 3.0's price by 1.5, adds 5 credits a second on O3 and costs nothing extra on Seedance 2.0. For exact lines in your own voice, use Lip Sync.

All three bill per second of output.

Kling 3.0: 12 credits a second on Standard, 16 on Pro (18 and 24 with sound).

Kling Omni O3: 14 on Standard, 19 on Premium (19 and 24 with sound).

Seedance 2.0: 7 at 480p, 15 at 720p, sound included.

For 10 silent seconds that's 120 or 160 credits on Kling 3.0, 140 or 190 on Kling Omni O3, and 70 or 150 on Seedance 2.0, which stays the same with sound.

A reference video changes Seedance's math: its seconds are billed together with the output at 4 credits a second (480p) or 9 (720p). A 10-second 720p clip guided by a 5-second reference costs (10 + 5) × 9 = 135 credits. Plans and top-ups: pricing.

A 9:16 teaser that must end on your packshot: Kling 3.0 with the packshot as end frame (Kling 3.0 guide), or O3 if the teaser has several beats.

A 12-second how-to with three distinct steps: Kling Omni O3, one segment per step (multi-prompt guide).

A square 1080p clip for a feed: Kling 3.0 Pro; Seedance 2.0 stops at 720p.

An idea with no image yet: Seedance 2.0 from text, or make a still in the Image Lab and use frames.

A clip that should follow a reference video's movement or a reference audio track: Seedance 2.0 (Seedance 2.0 guide).

A real performance copied onto your character: none of the three. Use Kling 3.0 Motion Control in Character Swap (motion transfer guide).

Seedance 2.5 is ByteDance's newest Seedance model in the Video Lab. It runs 4–30 seconds at 480p, 720p or 1080p, takes up to 10 reference images, a 2–30 second reference video and up to 30 seconds of reference audio, and has audio on by default. As on 2.0, frames and references are separate modes: set a first or last frame and only the frames are used. At 10, 22 or 39 credits a second it costs more, so choose it over 2.0 for clips past 15 seconds or 1080p output (Seedance 2.5 guide).

1. Make one first frame in the Image Lab, cropped to the format you'll publish.

2. Write one prompt with subject, action and camera: “A cyclist in her 40s stops at the top of a mountain pass and looks out over the valley. Slow push-in, low morning sun.”

3. Run 5 seconds on each at the cheapest settings: Seedance 2.0 at 480p (35 credits), Kling 3.0 Standard (60) and Kling Omni O3 Standard (70).

4. Compare motion, faces and how well each kept your frame, then render the winner at your final settings. For the wider field, including Veo 3.1, see AI video generators compared.
