Cuevo AI
Full-Stack AI Video Production Engine
From a single Studio workspace that plans, researches, and renders, to 9 specialized tools for voice cloning, lip sync, and translation — explore every capability that powers Cuevo AI.
Cuevo's Core Feature Matrix
Select a technology capability below to explore implementation details and target use cases.
Cuevo Studio
The all-in-one production cockpit. Upload any PDF/DOCX/Markdown, or just type a prompt — Studio plans a streaming storyboard via SSE, auto-researches facts from ArXiv & Nature, renders VFX equation cards, composites intro + presenter video with FFmpeg, and supports developer-level Git-tracked Markdown scripting with 30+ directional avatar gestures.
Directable AI Avatar
Inject action tags like [clap], [point_left], or [smile] directly into your script. The avatar moves with natural micro-expressions and precise hand gestures, completely replacing stiff robotic presentation.

Face & Accent Cloning
Replicate your digital likeness from a short recording and clone personal vocal accents using a 30-second audio clip. Supports fluent multi-language voice overs.
Lip-Synced Video Translator
Upload any voice video. Cuevo performs ASR, DeepSeek translation, clones voice timbre, automatically stretches video frames with setpts, and runs Talking Head to synthesize perfect lip-synced video.

Talking Photo AI
Upload a single portrait photo — the system separates facial landmarks, synthesizes natural head motion and lip movements driven by audio signals, and generates a lifelike talking-head video.
Lip Sync AI
Feed any video and audio track. The lip-sync engine detects vowels and consonants, calculates precise mouth aperture over the timeline, and redraws mouth movements frame-by-frame for flawless synchronization.
Audio to Video
Provide an audio narration track and the system generates matching visual animations, presenter movements, and scene compositions — turning voice recordings into polished video content.
AI Podcast Generator
Input a topic or script and generate a multi-speaker conversational podcast with distinct voices, natural turn-taking, and engaging dialogue — complete with visual presenter avatars.
Image to Video
Upload reference images and describe desired motion. The generation engine animates still frames into high-quality video footage with smooth camera movements and natural physics.
Text to Video
Type a text prompt describing the desired scene. The AI synthesizes matching video clips with coherent motion, lighting, and composition — no source media required.
Under the Hood Technical FAQ
Learn how we built our academic translation and directable rendering framework.
Studio is the full-stack production cockpit. It combines document parsing (PDF/DOCX/Markdown), live academic web research with cross-source citation, streaming storyboard planning via SSE, VFX equation card rendering, intro + presenter video compositing, and 30+ directional avatar gestures — all in a single unified pipeline. Individual tools specialize in one step like voice cloning or lip sync.
Cuevo calls the doc_parser backend to analyze PDF layouts and represent the document as a structured JSON tree. The system extracts LaTeX equations (rendered in equation_card), core experimental results, and network structures. DeepSeek then synthesizes a storyboard to seamlessly bind these VFX models into the final video.
Cuevo's Video Translator pipeline computes voice duration changes. The system uses a setpts filter to adaptively stretch or compress specific video segments. It then invokes the Talking Head lip-sync engine to redraw mouth movements based on the cloned audio, generating a localized video with natural lip sync.
