Made with this app
Kling O3 Standard brings the latest Kling architecture from Kuaishou to a single focused app, built around the scenarios where it genuinely excels: multi-character scenes where several people need to share the frame convincingly, voice-driven prompting for faster creative iteration, and custom image elements you can weave into a scene. It suits directors, social content creators, and brand teams who need short narrative clips, up to 15 seconds, featuring more than one character interacting with purpose.

What you can make
Two-character dialogue scenes
Kling O3 handles multi-character compositions where a single performer would feel incomplete. Describe two people in conversation, a job interview, a street encounter, or a product hand-off, and the model keeps both figures coherent and spatially consistent across the clip.
Voice-prompted creative briefs
Instead of typing out a full scene description, speak your idea using the voice input feature. This is practical when you are iterating quickly through concepts or when your brief is complex enough that dictating feels faster and more natural than composing text from scratch.
Brand content with custom elements
Upload specific image elements, a product, a logo treatment, a prop, and Kling O3 integrates them into the generated scene. This makes it useful for social ads or campaign teasers where a recognisable brand asset needs to appear alongside characters in motion.
Short narrative clips for vertical social
Set the aspect ratio to 9:16 and dial duration to suit a Reels or TikTok slot. The multi-character support means you can depict small story beats, two friends reacting to something, a coach and athlete moment, that feel more human than a solo-subject clip.
Storyboard animatics with native audio
Enable Generate Audio to add a native sound layer alongside your visuals in one pass. For animatic reviews and pitch decks, this removes the need to layer audio separately and gives stakeholders a more complete sense of pacing and atmosphere.

Tips for better results
Name each character explicitly
Because Kling O3 is built for multi-character scenes, give each person a role, relationship, or brief physical description in your prompt. Saying 'a nurse and a patient' gives the model clear anchors to maintain distinct identities across the clip.
Match duration to scene complexity
The Duration control runs from 3 to 15 seconds. Short durations work well for reaction shots and single gestures. Longer durations suit a sequence with movement, approach, interaction, and resolution. Choose the length that fits the narrative beat, not the maximum available.
Anchor custom elements early in the prompt
When you supply image elements, reference what they are near the start of your prompt text. Describing the element's role in the scene, rather than just its appearance, helps the model integrate it as an active part of the composition rather than a background prop.
Use Generate Audio for atmosphere, not dialogue
The native audio layer is well suited to ambient sound and musical tone. If your scene contains audible speech, write the mood and environment into the prompt so the audio generation has clear cues, but do not expect precise lip-synced dialogue from a text description alone.
When to choose this app
Choose Kling O3 Standard when your clip requires more than one character in the frame and when a custom visual element or voice-driven prompt is part of your workflow. Seedance 2.5 and Seedance 2.0 are strong alternatives for longer-form or cinema-grade video, but neither is specifically designed around multi-character composition or custom element input the way Kling O3 is. Wan 3.0 offers omni-reference and a single 30-second pass, which suits different use cases. Kling O3 is the right pick when the multi-person scene is the creative challenge.
Frequently asked questions
How many characters can appear in a single Kling O3 clip?
The model is designed for multi-character scenes, meaning you can describe two or more distinct people sharing the frame. There is no published hard cap on the number of figures, but clarity in your prompt, naming roles and positions, improves coherence when more than two characters are present.
What kinds of image elements can I supply as custom inputs?
You can provide specific product images, props, or other visual references that you want integrated into the generated scene. The model treats them as compositional elements rather than style references, so describing how they appear or what role they play in the scene helps the output match your intent.
Does voice input replace the text prompt or work alongside it?
Voice input is an alternative way to supply your scene description. It transcribes and submits your spoken brief in place of typed text. You do not need to combine both; simply speak your prompt when that is more convenient than typing, particularly for longer or more complex descriptions.
What is the longest clip I can generate with this app?
The Duration control allows up to 15 seconds per generation. This is sufficient for short narrative beats, social content, and animatic segments. If your project needs a longer single-pass clip, you would need to consider a sibling app designed for extended durations.
Which aspect ratio should I choose for a story-format social post?
Select 9:16 using the Aspect Ratio control for vertical formats such as Instagram Reels, TikTok, or YouTube Shorts. Use 16:9 for widescreen presentations or landscape embeds, and 1:1 for square feed posts. The control sets this; you do not need to describe it in your prompt.
Can I generate a clip without audio even though the model supports it?
Yes. The Generate Audio control lets you decide whether native audio is included. If your project will receive custom sound design in post-production, or if you simply want to review the visuals first, leave Generate Audio off and the output will be a silent video file.
Which AI model powers this app?
This app runs on Kling O3, available through Arteza with no separate account or setup.
Can I use the results commercially?
Yes. Content you generate is yours to use, subject to our content licenses.
How long does a generation take?
Most generations finish in under a minute, and you can watch progress live in the gallery.
