Windows, Linux and the sources: Get started.

A · Night launchv1

Variant A, Night launch: the launch title in light violet type over a starfield.

B · Paperv1

Variant B, Paper: the launch title in ink and blue on warm paper.

C · SignalChosen

Variant C, Signal: the launch title in teal monospace over a navy grid.

A launch video for Motion Studio. Three variants.

Three directions on the canvas: Night launch, Paper and Signal. Pick one and I’ll carry it through every format.

You chose C · Signal.

The chat in this story is a demo: scripted messages, real features. Every board is a real composition, played by Motion Studio’s own runtime.

02 · Ask Change it with one sentence.

Say what you want in plain words. The agent makes a new version and keeps the old one, so nothing you liked is lost.

C · Signalv2

Signal v2: the title 40% larger over a teal flash.

Make the title bigger, more energy.

v2 is ready: the title is 40% larger and slams in on a flash. Same layout and timing everywhere else.

03 · Edit by hand Or move it yourself.

Drag, resize and recolour any layer in the editor, then save it as a new version. No agent, no tokens.

C · Signalv3

Signal v3: the title moved lower, resized and recoloured yellow by hand.

Direct edits in the editor: the title moved, resized and recoloured. Saved as v3.

04 · Brand Your brand, read from your site.

Paste a website: its palette, fonts and logo become a brand kit, each with where it came from. Your edits stay.

C · Signalv4

Use our brand: aleloca.github.io/motion-studio

Read it: a #0F0F0F stage, #FF5A1F orange, Bricolage Grotesque and Instrument Sans, and the logo. v4 wears them, and your edits stay.

05 · Generate Pictures, voices and music, on your keys.

Images from OpenAI, voice-overs, music and sound effects from ElevenLabs, with your own keys. Every paid call waits for your OK.

C · Signalv5

v5: the generated backdrop, warm light through haze and floating frames, behind the branded title.

Voice-over · Eric

Music · music_v1

Add a cinematic backdrop behind the title, a voice-over and a music bed.

Made on your keys: the backdrop with gpt-image-2, now behind the title in v5, and with ElevenLabs the voice-over (Eric, eleven_multilingual_v2) and the music bed.

06 · Formats Every format, recomposed.

The chosen 16:9 becomes a Reel and a square post, each laid out again for its own frame. Never cropped.

C · Signal 16:9v5

The chosen variant, C · Signal v5, in 16:9: the 9:16 and the 1:1 are recomposed from it.

Post 1:1

Reel 9:16

Also make it for Reels and Instagram posts.

Done: a 9:16 and a 1:1, each recomposed for its frame. The mark leads the Reel, the title stacks under it.

07 · Languages Any language, one layout.

Name the languages and Claude translates. Only the words change: positions, timing and colours stay, and every line fits its box.

16:9 · English

16:9 · Italiano

16:9 · Deutsch

16:9 · Español

Italian, German and Spanish too.

Three translations. Positions, timing and colours are the original’s, and every line fits its box at the same size.

08 · Subtitles Subtitles, timed to the word.

Transcribed from the voice-over on your computer, drawn on the video in sync, and one click from an .srt or a .vtt.

C · Signalv6

v6: the title over its backdrop with subtitles, each word lit as it is spoken.

Add subtitles from the voice-over.

Transcribed locally with Whisper: two lines, each word timed. They’re drawn on the 16:9, and .srt and .vtt are one click away.

09 · Export One click, every channel.

Every starred version rendered on your computer and named for its channel. Existing files are never overwritten.
