Made with this app
How it works
Kling O3 Standard brings Kuaishou's latest Kling architecture to Arteza's text-to-video suite, purpose-built for scenes that require more than a single subject. With native multi-character support, custom image element input, and voice audio baked directly into generation, it is designed for creators who need to direct populated scenes, dialogues, or branded vignettes without stitching clips together in post. Videos run between 5 and 10 seconds, making it practical for social content, storyboards, and short narrative beats.

What you can make
Two-Character Dialogue Scenes
When a script calls for two people interacting, Kling O3 handles multiple characters within a single generation. Writers and filmmakers can prototype conversation moments, pitch scenes, or social ads featuring distinct characters without splitting the action across separate clips.
Voice-Driven Character Animation
Kling O3 accepts custom voice input natively, so spoken audio shapes the scene rather than being layered on afterward. Podcasters, educators, and advertisers can anchor a video to a specific vocal delivery, keeping lip timing and pacing tied to the real audio from the start.
Brand Asset Integration
The custom elements feature lets you feed in your own images as scene components, making it useful for product demonstrations, logo placements, or character designs that must stay visually consistent. Marketers can ground a generated video in existing brand visuals rather than working from text alone.
Short Social Narrative Clips
At 5 to 10 seconds, Kling O3 fits the attention window of Reels, Shorts, and TikTok stories. Content teams can generate complete micro-narratives with multiple actors and native audio in one pass, skipping the assembly work that single-character models require.
Storyboard Animatics
Directors and animators can use Kling O3 to produce quick animatics for scenes involving crowds, couples, or ensemble casts. The multi-character capability means each beat can be previewed with the correct number of on-screen figures before committing to full production.

Tips for better results
Name Characters Explicitly
Because Kling O3 supports multiple characters, label each figure clearly in your prompt, for example 'Character A, a tall man in a grey coat' and 'Character B, a woman in a red scarf.' Distinct descriptions reduce visual overlap and give the model clear cues for each subject.
Match Voice Input to Scene Pacing
Native audio input means the voice you supply influences timing across the full clip. Keep recorded audio between 4 and 9 seconds so it maps cleanly to the 5 to 10 second output window and avoids abrupt cutoffs at either end.
Anchor Custom Elements Early in the Prompt
When uploading custom image elements, reference them at the start of your text prompt rather than the end. Describing the element first gives Kling O3 a compositional anchor before additional scene details are introduced, improving how it integrates your asset into the frame.
Specify Spatial Relationships
Multi-character scenes benefit from clear spatial language: 'standing face to face,' 'one seated, one standing behind,' or 'side by side walking left.' Explicit positioning reduces ambiguity and helps the model distribute characters across the frame in a readable way.
When to choose this app
Choose Kling O3 when your concept depends on more than one character interacting, requires custom visual elements, or needs voice audio integrated at generation time. Sibling apps like Seedance 2.0 and Seedance 2.0 Mini excel at fluid single-subject motion, and Sora 2 delivers high cinematic fidelity, but neither offers the same combination of multi-character staging, custom element input, and native voice support that Kling O3 provides in a single generation.
Frequently asked questions
How many characters can appear in a single Kling O3 generation?
Kling O3 is built for multi-character scenes, and while no hard cap is published, prompts featuring two to four distinct characters with clear descriptions tend to produce the most coherent results. Crowded scenes with many unnamed figures are less reliable than scenes with a small, well-described cast.
What kind of audio file works best with the voice input feature?
Kling O3 accepts custom voice input natively, and clean mono recordings with minimal background noise perform best. Keep your audio clip within the 5 to 10 second output range to ensure it aligns with the generated video duration without gaps or forced truncation.
How do custom image elements affect the final video?
Custom elements let you supply your own images as compositional anchors, such as a product, a logo, or a character design. Kling O3 incorporates these into the generated scene rather than generating entirely from text. Results are strongest when the element has a clean background and a clear main subject.
Can I control which character speaks when using voice input?
Voice input sets the audio track for the overall scene. The model uses contextual cues in your prompt to associate speech with the appropriate character, so specifying which character is speaking in the prompt text, for example 'the woman on the left explains,' improves alignment between audio and on-screen action.
Is the 5 to 10 second duration range user-selectable or automatic?
The duration range for Kling O3 is 5 to 10 seconds. Whether you set a specific target length or the model determines it from the prompt depends on the generation interface, but the output will fall within that window. Providing audio input or specifying a scene length in your prompt gives the model clearer duration guidance.
How does Kling O3 Standard differ from other Kling versions available on Arteza?
Kling O3 Standard represents the latest Kling architecture from Kuaishou and is the only Kling model on Arteza that combines multi-character support, voice input, and custom element integration in a standard quality output. Other Kling versions on the platform may differ in architecture generation, supported features, or output quality tier.
