Overview

Three sentences about what the AI agent does and its benefits.

The AI agent accepts a topic prompt and delivers a complete 9:16 short from script to render. It automatically writes a hook-based script, sources stock footage, generates a consistent voiceover, and adds captions and music. The final MP4 is produced in a consistent format for scalable publishing.

FAQ

FAQ

Practical, real concerns answered with detail.

The AI agent requires a topic prompt and optional style preferences. A form or API input provides the topic, audience, and tone. The agent then generates a ~100-word script, creates eight visual search terms, and selects stock footage accordingly. It also triggers the voiceover generation and prepares the assets for rendering. This keeps the process tight and auditable from prompt to render.

Yes. You can specify a target length and tone. The script generator adapts to preferred word counts and style guides, while ElevenLabs provides multiple voice options and controllable speech characteristics. You can adjust pacing, emphasis, and language to match your brand. Changes apply before rendering, ensuring consistency across outputs.

The AI agent searches multiple related terms and substitutes with similar visuals when needed. If a term yields no suitable clip, it expands or tweaks the search criteria and tries alternative terms automatically. If no suitable assets exist, it can flag for a manual review rather than producing a low-quality edit. This keeps outputs reliable while avoiding gaps in content.

Yes. You can choose from a set of ElevenLabs voices and adjust parameters like pitch, tempo, and intonation. Language options depend on ElevenLabs availability, and you can mix languages if needed. The settings apply to the final render, ensuring the voice matches the script and audience. If you need a bespoke voice, you can provide a reference or request a new model integration.

Rendering time varies with video length and template complexity, but the AI agent streams progress and replies with status updates. Typical renders complete within minutes for standard 9:16 templates. The system polls the render service until status is 'succeeded' and then performs cleanup and metadata updates. You can expect near-real-time turnaround for single videos and batch processing for multiple topics.

Yes. You can reuse script structures, stock footage selections, and voice profiles across topics. Templates can be saved or cloned to maintain brand consistency. Asset libraries (clips, music, voices) can be cached for faster subsequent renders. Reuse reduces setup time and helps maintain a uniform look and feel.

The current workflow is optimized for vertical 9:16 Shorts. The underlying components can be adapted to other aspect ratios with a template change. If you need alternative formats (e.g., square or landscape), we can configure a variant and map assets to the respective layers. This ensures you can tailor outputs for different platforms or campaigns.
