About this offering: Runway Seedance 2 — the current Runway flagship for video generation. Three variants: seedance2 (standard, up to 4K), seedance2_fast (faster, 480p/720p), seedance2_mini (lowest cost, 480p/720p, 64-credit minimum). All variants support T2V, I2V, and V2V modes; durations 4–15 seconds. Features: keyframe control, reference images, reference videos, native audio generation. All tiers use the flat $0.01/credit Runway developer API rate. 4K support (150 cr/s) added June 24, 2026.

Capability profile

How Seedance 2 rates across core capability dimensions, with the task-level evidence behind each rating.

Prompt adherence Strong

Current Runway flagship; Runway highlights strong text fidelity. No independent benchmark data available as of 2026-07-02; rated strong based on flagship positioning and T2V first-class support.

temporal consistency Strong

V2V support implies strong temporal modeling; reference video conditioning requires consistent frame-to-frame handling. Rated strong provisionally.

motion quality Strong

Flagship Runway model positioning implies best-in-class motion quality within the Runway lineup. No third-party benchmark data as of 2026-07-02.

native audio Moderate

Native audio generation is supported ("generated audio" listed as a feature). Quality relative to Veo 3.1 or HappyHorse 1.0 is unconfirmed. Rated moderate pending independent audio quality evaluation.

camera control Unknown

No documentation or evidence of camera control parameters as of 2026-07-02.

character consistency Moderate

Reference image and reference video inputs suggest character consistency conditioning. No dedicated benchmark data; rated moderate pending evaluation.

Resolution ceiling Strong

4K output is supported (150 cr/s, $1.50/s) across six aspect ratios (3840:2160, 3840:1646, 3840:2880, 3840:3840, 2880:3840, 2160:3840). Added 2026-06-24. Highest resolution ceiling among Runway models.

Inference speed Moderate

Standard (seedance2) is not the fastest variant; Fast (seedance2_fast, $0.29/s) and Mini (seedance2_mini, $0.16/s) variants exist for latency-sensitive use. Relative to other providers, speed is unknown without benchmarks.

clip duration ceiling Strong

4–15 seconds per call. 15 seconds is among the longest clip durations in the video generation registry, surpassing most competitors (typically 8–10s).

image to video quality Strong

Flagship Runway I2V. No independent I2V benchmark as of 2026-07-02.

Compositional accuracy Unknown

No benchmark data available as of 2026-07-02.

cost efficiency Moderate

Standard at $0.36/s (720p) is expensive relative to alternatives. Mini at $0.16/s (720p) is more competitive. High cost reflects premium positioning and feature set (V2V, audio, 4K, longer clips).

video editing Unknown

V2V mode is exposed via the API ("video" listed as a supported input). However, the nature of the V2V capability is not documented in sufficient detail to rate confidently — it may be style transfer / video-conditioned generation rather than prompt-driven modification of existing footage. Rated unknown pending confirmed documentation of the V2V editing mechanism.

Ratings are estimated — limited independent data is available for this model.

Operator guidance

Current Runway flagship for video generation. Standard ($0.36/s, 720p) or Standard 1080p ($0.40/s) for production-quality work. Mini ($0.16/s, 720p) for cost-sensitive T2V/I2V pipelines that don't need 4K or 1080p. Standard 4K ($1.50/s) is the most expensive option in the Runway lineup — reserve for projects where 4K is required. For I2V-only at minimum cost, Gen-4 Turbo ($0.05/s) remains relevant. For T2V/I2V without audio at lower cost, Gen-4.5 ($0.12/s) is an alternative. Seedance 2 supersedes Gen-4.5 as the default recommendation for new Runway projects as of mid-2026: it adds V2V mode, native audio, 4K output, and up to 15s clips.
