Make the launch film for Tandem. Dark paper and ink, serif titles, our violet. Pull the pricing copy from the repo.

Nine scenes, one continuous cut: the mark, the thesis, the ask, the build, the pricing reveal. Every frame passed the gate.

Scene 2 here: the headline drifts off the right edge, and it reads dim.
Measuring… 18px from the right edge, the gate wants 64. Ink at Lc 41, the floor is 45.

Made, not generated.

Every video is built scene by scene on a real timeline. And when it's done, you can still open it up and change anything.

Launch videos

Point it at your repo. The agent reads your product, design system, and copy, then cuts a launch video in your brand.

Assets to video

Drop in screenshots, clips, logos, and audio, tag them in the prompt, and the agent times and animates them on the timeline.

Motion graphics

Text, shapes, charts, and transitions, animated in code with real springs. The agent checks every frame before you see it.

Short-form

9:16, styled captions, cuts on the beat. Post it to TikTok, Reels, or Shorts the same hour.

You already pay for a film studio.

EndFrame puts Claude, ChatGPT, and Grok to work on your Mac. If you pay for any one of them, that's all EndFrame needs. No API keys.

01

Describe the video

One prompt in the composer. Tag your assets, pick a style, or point it at your repo.

02

The agent builds it

It writes real scenes on a real timeline, renders frames of its own work, and fixes what looks wrong.

03

Edit anything, then export

Scrub, trim, go back to any version, adjust any detail. Export in 1080p or 4K, rendered on your Mac.

It reviews its own work.

After every edit, the agent renders real frames and looks at them. It measures margins, checks text contrast, and runs a 33-rule quality gate. If something is off, it fixes it before you see it.

Six things you'll use every day.

Built the way a video tool should feel: fast, hands-on, and easy to undo.

Tag anything into the prompt

Drop images, clips, and audio into the composer as chips, along with skills and connectors. The agent sees exactly what you see.

Capture the frame, fix the frame

Stop on the frame that's wrong, capture it, and say what's off. The agent gets the exact pixels. No screenshots, no long explanations.

A timeline you can feel

Hover to scrub, instantly. Trim, reorder, and delete clips without breaking anything the agent made.

Every version, one click back

Every edit, yours or the agent's, becomes a version you can return to. Preview any point in time and restore it without worry.

Your look, saved

Turn any project's style into a reusable template: colors, type, motion, and a real rendered preview.

Export in one click

1080p or 4K, rendered on your Mac. The preview and the export share one engine, so what you see is exactly what ships.

Everything else is one connector away.

Voiceover from ElevenLabs. Footage from Runway, Higgsfield, or fal.ai. Designs from Canva, copy from Notion. One prompt can carry a video from start to finish.

Fifteen one-click connectors, or add any MCP server with a URL, a command, or a config file.
