## About Kling V2.1 Standard

Kling V2.1 Standard is the entry tier of the Kling 2.1 video generation lineup that Kuaishou, the Beijing company behind the Kwai short-video platform, released in May 2025. Kling first opened for public testing in June 2024 inside Kuaishou's KuaiYing editing app, and the 2.1 release was the first to split the model into tiered quality modes so users could trade generation cost against output fidelity. The Standard tier is the image-to-video workhorse of that lineup: it takes a still image and animates it into a short clip.

On Artifio the model runs alongside more than 100 others in one workspace, paid per generation from a single wallet with no per-model subscription.

## Features

- Animates a still reference image into a video clip; the 2.1 release centers on frame-based image-to-video generation.
- Generates clips of 5 or 10 seconds per run.
- The Kling family outputs video at up to 1080p and 30 frames per second across a range of aspect ratios.
- Built on a diffusion transformer with Kuaishou's self-developed 3D variational autoencoder and a full-attention spatiotemporal module, which models motion across frames rather than frame by frame.
- Part of the tiered 2.1 lineup introduced in May 2025, where Standard is the fastest and cheapest quality mode.

## What people use it for

- Turning product photos into short motion clips for listings and ads.
- Animating concept art or storyboard frames to test how a scene reads in motion.
- Producing social media posts that add movement to an existing still image.
- High-volume iteration where many candidate animations are generated cheaply before committing a stronger tier to the final render.

## Reported strengths

- Reviewers singled out realistic motion and physics simulation, which Kuaishou attributes to the 3D spatiotemporal joint attention design.
- Expressive character movement and natural motion from a single source image.
- Low cost per clip relative to the Pro and Master tiers makes it practical for bulk drafts.

## Reported limitations

- The Standard tier works from a reference image; generating from a text prompt alone was not supported on this tier at launch.
- Clips top out at 10 seconds per generation.
- Kling 2.1 produces silent video, and at review time the companion audio feature generated Chinese-only speech without automatic lip sync.
- Kling operates under content rules aligned with Chinese government regulations, so politically sensitive prompts are refused.
