Kling 2.1 is the proven mid-generation of Kuaishou’s video family, and on Veo AI it arrives as a four-endpoint lineup: Pro, Standard, and a Master pair split into text-to-video and image-to-video. That spread makes 2.1 the flexible pick — budget takes and premium takes live under one roof.
Each tier has a distinct job. Kling 2.1 Pro is the image-to-video specialist and the only Kling endpoint on the platform with first-and-last-frame keyframes plus negative prompts — bookend a shot with two stills and it animates the journey between them. Standard is the economical all-rounder accepting text or image input, while the Master variants aim at top-shelf detail in either mode.
All four render 5 or 10 second clips at 720p or 1080p; Standard and Master text-to-video add a 1:1 square option beside 16:9 and 9:16. Reference images and style presets are supported on the image-capable endpoints, so a recurring character can survive across an entire batch.

What makes Kling 2.1 stand out
First & last frame
Kling 2.1 Pro interpolates between two stills you supply — plan transitions, reveals, and product turns shot by shot.
Three quality tiers
Standard for volume, Pro for controlled image-to-video, Master for maximum detail — pick per shot, not per project.
Cleanup via negatives
The Pro endpoint takes negative prompts, letting you veto artifacts and off-brief elements before rendering.
Both input modes
Master ships as separate text-to-video and image-to-video variants, and Standard handles either from one endpoint.
Consistent subjects
Reference-image support on the image endpoints keeps a face or product steady across a multi-clip series.

Kling 2.1 questions, answered
What is Kling 2.1?
Kling 2.1 is a widely used generation of Kuaishou’s Kling video model, available on Veo AI in Pro, Standard, and Master tiers. It produces 5 or 10 second clips at 720p or 1080p from text prompts or images.
What is the difference between Kling 2.1 Pro, Standard, and Master?
Pro focuses on image-to-video with first/last-frame keyframes and negative prompts. Standard is the lower-cost generalist for text or image input. Master splits into dedicated text-to-video and image-to-video variants tuned for the highest 2.1 fidelity.
How do first and last frames work in Kling 2.1?
On the Pro endpoint you upload an opening still and a closing still; the model generates the motion connecting them. It’s the most precise way to control where a Kling shot begins and ends.
Does Kling 2.1 do text-to-video?
Yes — through the Standard endpoint and the Master text-to-video variant. Both render 5 or 10 seconds at up to 1080p in 16:9, 9:16, or 1:1.
Is Kling 2.1 still worth using over newer versions?
Often, yes. Newer Kling releases raise fidelity and length, but 2.1 uniquely offers keyframe bookends on Veo AI, and its Standard tier is a friendly credit price for high-volume drafting.
Can Kling 2.1 keep the same character across clips?
The image-capable endpoints accept a reference image, which anchors a subject’s appearance from generation to generation — useful for episodic content and brand mascots.
