How it works

Direction, not just generation.

Most AI tools give you ten seconds of random footage. Arch gives you a director that reads your brief, plans every cut and locks every character — whether it's a clip synced to your music or a short film born from a single idea.

The pipeline

Three phases. One vision.

Whether you start from a music track or a text idea, every render goes through the same three craft stages. Most of the visible quality comes from phase one — the one nobody else does.

01

Direction

Your brief becomes a film treatment.

  • A story bible captures the world, the characters, and the visual identity.
  • A shot plan breaks your brief into precisely timed cuts, each with its own framing and intent.
  • Every reference image is mapped to its role: main, supporting, environment, style.
02

Filming

Each shot is filmed individually.

  • A starting frame is generated from the shot plan.
  • The video model animates it — 1.5 to 5 seconds, motion-driven.
  • The last frame of each shot anchors the next, keeping the world coherent.
03

Assembly

Cuts, audio, delivery.

  • Every shot is concatenated in narrative order.
  • Your audio (or the generated soundtrack) is cleanly muxed with the footage.
  • The final video is uploaded — ready to download or share.
The craft

Where the difference lives.

Six things Arch does to turn an AI clip generator into a real video studio, whatever the mode.

A real AI director, not a single prompt

Most tools take your prompt and roll the dice. Arch runs multiple specialised AI passes in sequence: a story builder, a section planner, a shot planner, a prompt writer, a validator, a sanitizer. Each one has a job. The result is direction — not chance.

Editing locked to your music

In Music Video mode, rhythmic structure, vocal energy, BPM and dynamic shifts are analyzed from your audio. Cuts land on the strong beats, tempo follows the song's arc, choruses cut faster than verses. The upcoming Visual Narrative mode will instead follow the rhythm of your story — dialogue, silences, the tension of each scene.

Characters that don't drift

Each character's physical identity is described once and injected into every shot prompt — same hair, same outfit, same distinctive features across the whole video. No morphing faces between cuts.

You write briefs, not prompts

Tell Arch the story, the mood, the look. It translates that into hundreds of carefully crafted cinematographic prompts — one per shot — using the right vocabulary for each model. You stay creative; the machine handles the wording.

Refine shot by shot

A bad shot doesn't mean restarting the render. Hover any cut in your timeline, click recreate, and only that shot regenerates. The final video rebuilds itself. Credits go toward what actually needs work.

Your keys, your costs

Bring your own Gemini API key. We don't resell tokens or hide markup. You see every cost, you keep control. Arch only charges for the rendering — the part we actually do.

What you give

Your inputs. A whole video.

Text idea — Visual Narrative
The starting point of Visual Narrative mode. Describe your story, characters and world — and Arch turns it into a cinematic short with dialogue and sound, no music required.
Creative guidance
The core of both modes. A single sentence or a full treatment — your story, mood, characters, locations, visual style. In Visual Narrative, this brief alone is enough. You decide the depth.
Audio — Music Video
Up to 5 minutes, MP3 or WAV. In Music Video mode, Arch reads tempo, beats, vocals and dynamic structure to drive the edit.
Reference images
Optional. Up to 9 slots: main character, supporting cast, environments, and one style reference. Locks identity across the whole video.
Lyrics — Music Video
Optional. In Music Video mode, [Verse], [Chorus], [Bridge] tags help align cuts to the song's structure. Auto-detected if omitted.

That's it. No timeline editing, no per-shot prompting, no model settings to tune. Arch handles the craft, you stay focused on direction.
