Apple's June 30, 2026 Creator Studio update brings Generate Captions and Edit Detection to Final Cut Pro on Mac and iPad, plus Mac-only Auto Mask — all running on device.

On June 30, 2026, Apple shipped a free update to Apple Creator Studio that added a round of on-device AI editing tools to Final Cut Pro, delivered as Final Cut Pro 12.3. The headline additions are Generate Captions and Edit Detection — both on Mac and iPad — plus Auto Mask, which is Mac-only.
Generate Captions automatically transcribes a clip's audio and places the subtitles directly in the timeline, where you can restyle the font, color, position, and animation. It runs entirely on device and, at launch, supports U.S. English only. It requires an Apple-silicon Mac on macOS 15.6 or later, or an iPad with an M1 chip or later (plus the A16 and A17 Pro iPads) on iPadOS 26 or later. Apple framed auto captions as one of Final Cut's most-requested features.
Edit Detection analyzes a rendered, flattened video — one exported as a single file with no separate clips — finds its shot changes, and splits it back into individual clips on the timeline with a click. Auto Mask (Mac only) isolates elements like skin, hair, sky, foliage, and clothing without manual tracking, working alongside Magnetic Mask and the color tools. The update is free for existing Apple Creator Studio subscribers, the $12.99/month bundle Apple introduced in January 2026.
Final Cut's Generate Captions solves the easy half of the problem: turning speech into subtitles once, on one timeline. The hard half is that captions are not one-size-fits-all. A 9:16 TikTok clip, a 1:1 LinkedIn square, and a YouTube Short each want their own caption style, safe-zone placement, and length, and a growing audience often wants a second language — none of which a single captioned master produces. Kompozy is where one captioned edit becomes many captioned posts.
Drop a Final Cut export into Kompozy and the Clipped Shorts engine cuts vertical shorts from the long edit and burns word-synced captions onto each one automatically — no Apple-silicon requirement and no single-language ceiling. Persona Shorts and the other video formats caption themselves the same way, and the copy for every destination is written per platform from the Persona Brief. Kompozy then schedules and publishes across Instagram, TikTok, YouTube, LinkedIn, X, Facebook, Pinterest, and Threads, plus blog and email, on autopilot with Trigger.dev workers that keep running after you close the tab. Use Final Cut 12.3 to caption the master; use Kompozy to re-cut, re-caption, and ship it everywhere.
On June 30, 2026, Final Cut Pro 12.3 added on-device Generate Captions (auto-transcribed subtitles placed and styled in the timeline) and Edit Detection (re-splitting a rendered video into its original clips) on both Mac and iPad, plus Auto Mask on Mac. It shipped free to Apple Creator Studio subscribers.
At launch it supports U.S. English only. Because it runs on device, it also needs an Apple-silicon Mac (macOS 15.6 or later) or an iPad with an M1 chip or later. Apple may add languages over time, but as of the June 30, 2026 update, U.S. English is the only supported caption language.
Edit Detection analyzes a rendered, flattened video — one exported as a single file with no separate clips — finds its shot changes automatically, and splits it back into individual clips on the timeline with a click, so you can re-edit footage you no longer have a project file for.
No. Final Cut generates captions on one master timeline in one style and aspect ratio, and it has no scheduling or publishing. To turn that captioned master into platform-native captioned clips and post them across multiple feeds, you pair it with a content generation and multi-platform publishing engine like Kompozy, which also generates net-new persona video, images, carousels, blogs, and newsletters — and re-cuts, re-captions, and publishes on autopilot.
