Say the edit.
Watch it happen.

Captions, vertical cuts, the moment she says the thing. Ask for it, then keep editing by hand.

The Aria editing window: clips and an agent's suggested edit on the left, the video preview in the middle, effects on the right, and a six track timeline underneath.

Claude OpenAI Model Context Protocol

Ask in plain words. Keep the timeline.

Aria does the tedious half. What comes back is not a locked export, it is ordinary clips on ordinary tracks that you can drag, restyle, trim or throw away.

Caption this with karaoke Word-timed caption clips on their own track, styled from a preset, editable afterwards like anything else.
Make it vertical and keep her in frame Faces get tracked, the crop follows them with keyframes, and a 16:9 interview becomes a 9:16 short.
Find where she says "the best part" and cut there Transcript search with word-accurate timings, so the cut lands on the syllable rather than near it.
Break this into scenes Shot boundaries detected once and cached, so an hour of footage stops being a wall of thumbnails.
Pull the music off the vocals Separated stems land as their own audio clips, ready to duck, mute or replace.
Subtitle this in Spanish A local model translates the transcript sentence by sentence, and the captions keep their timing, preset and karaoke.
An Aria timeline with six stacked tracks: an adjustment layer, an overlay image, three title clips, shape clips, and an audio track with a waveform.
The result is a timeline, not a black box.

Everything it makes is a real clip with real properties, still yours to change.

Captions that time themselves.

Aria listens to your audio on your own machine, word by word, then builds the caption clips and animates the highlight in one step.

One take, thirty languages.

Transcribe, pick a language, translate. A model on your own machine reads whole sentences rather than words, keeps the names and jargon you tell it to, and delivers the same caption clips, presets and karaoke as any transcript. Nothing is uploaded, and it keeps working with no connection.

She says: “The best part is the last ten seconds.”

Spanish

Lo mejor son los últimos diez segundos.

French

Le meilleur moment, ce sont les dix dernières secondes.

Japanese

一番いいのは最後の10秒。

Arabic

أفضل جزء هو الثواني العشر الأخيرة.

And a real editor underneath.

None of it matters if the editor is a toy. Aria grades, keys, masks, keyframes, mixes and exports, and the preview shows you what the export will do.

Keyframes with curves you can feel

Animate anything with a number on it. Pick an easing per segment or bend the curve by hand, and the preview follows as you drag.

Aria's animation panel showing an opacity track with two keyframes, a curve editor, and a row of easing presets.

Every ratio, one project

Cut once, then reframe for wherever it is going. Crop on the canvas by hand, or let a tracked face carry the crop for you.

Masks and transitions on the clip

Ellipse and polygon masks, invertible and animatable. Transitions belong to a clip edge, so nothing can drift out of sync with the cut.

Aria's inspector showing opening and closing transition menus for a clip, and an ellipse mask with position, size and rotation controls.

Frame it on the picture

Drag and resize a clip on the preview itself, or type exact numbers. What you see is what renders, at full quality, every time.

Aria's video preview with a selected clip, drag handles on every corner, and a readout of its position and pixel size.

Titles that arrive finished

Fifteen looks and nine motions, each drawn as the frame it makes. Drag one to the timeline, then change any of it, because it is a text clip like any other.

Backgrounds without a stock library

Gradients, checks, stripes, dots and grids, drawn at whatever size you deliver at. A ramp to transparent is the scrim that makes a title readable over a bright shot.

Scopes while you grade

Waveform, RGB parade, vectorscope and histogram under the picture, live as you drag a slider. So a grade that looks right is also right.

Exports that keep up with you

A graded 54-second project took three and a half minutes and now takes nine seconds. Aria decodes, composites and encodes on the graphics card, as MP4 or QuickTime .mov.

Speed as a curve, not a number

One rate for the whole clip, or points you drag: slow in, fast through the middle, normal again by the cut. Audio keeps its pitch and the clip's length follows.

Aria's speed panel showing a rate slider overridden by a three-point speed curve, with four curve presets under it.

Seventy-nine effects, and none of them lie to you

Grades, keys, LUTs, blurs and distortions, plus EQ, compression and reverb for sound. Every parameter has a declared range, so a bad value is caught while you are editing rather than found in the export.

Use the AI you already pay for.

Aria writes the connection for you. Point Claude Code, the Claude app or Codex at the window you have open, and it edits alongside you.

One dialog, then it is set up

Tick the assistant you use and press Install. Nothing is written to your machine until you do, and one uninstall takes it back out.

You watch it work

Clips appear on your timeline as they are made, in the window you already have open. No round trip, no waiting on a render to see what you got.

Command Z is the review

Its edits share your undo history, so taking one back is the same keystroke as taking back your own. The History panel names who made every change, and walks you back to any of them.

It checks its own work

It can render a frame off your timeline and look at it, so a caption that fell off screen gets fixed before you ever see it.

It follows your house style

Write down how your videos look once, in your own words, and it reads that before it makes a design choice. Keep your colours, your fonts and your logo in a kit, and point a project at the kits it should follow.

Aria's Connect Claude dialog offering Claude Code, the Claude app and OpenAI Codex, noting that nothing is written until Install is pressed.

If you like to tinker, it goes deeper.

Everything the app can do is a scripted API. Feed it a spreadsheet of clips, batch a hundred shorts, or build the edit you always make out of a loop.

assemble.py
import aria project = aria.connect()video = project.timeline.track("V1")captions = project.timeline.add_track("text", name="Captions") with project.transaction("Assemble the cut"):    for shot in aria.read_json("shots.json"):        clip = video.append(shot["file"], duration=shot["seconds"])        clip.fade_in(0.3)        captions.add_clip(text=shot["caption"], start=clip.start)
