Origin story
It began with 886 × 1920 px.
A portrait App Store preview for iPhone is 886 by 1920 pixels and 30 frames per second. Most video editors can't handle that, and professional apps require a multi gigabyte download and still make it needlessly hard.
This is where PictureWriter shines. You choose a preset and get going. Everything after that, the viewer, the titles, the export, works at that size.
The app makes use of the built-in frameworks that come with your Mac, which keeps it small and snappy. It focuses on the fun part of making movies.
The transition catalogue
96 ways to move between shots.
You'll find the plain dissolves and wipes here. But the app is also packed with reel changes, tape rewinds and other playful recreations from movies and TV.

Overlays
Picture in picture, split screen and cutaways, with animated moves, rounded corners, shadows and borders.
Audio

Speech is transcribed on your Mac and laid out as captions that you can edit like any other title.
Requires macOS 26 or later

Turn on your Mac's camera, or a nearby iPhone, and try effects on the live video.
Export
H.264 video and AAC audio in MOV or MP4, at the project's size and frame rate. HDR supported.

PictureWriter is a free download, and every feature, transition and effect is available. Nothing is locked or limited.
Videos you export carry a watermark. A single purchase removes it. There is no subscription.
Questions
Questions you may have.
What is free and what isn't?
PictureWriter is free to download, and all features are included. Exported videos include a watermark. A one-time purchase of $9.99 removes it. There is no subscription.
Do my videos leave my Mac?
No. PictureWriter doesn't upload your videos, projects, or recordings, and it doesn't require an account.
These features run on your Mac, using Apple frameworks:
- Person detection
- Voice isolation
- Speech transcription for closed captions
- On-screen text for the Trailer Card and Computer Terminal transitions
PictureWriter stores working files, such as person masks and reversed clips, in a cache folder on your Mac. Voiceover recordings are saved in Movies/PictureWriter/Voiceovers.
The first time you use a caption language, macOS downloads the speech model for that language from Apple. Your audio isn't sent to Apple.
Activating a license sends your license key and your Mac's name to Lemon Squeezy, which handles the purchase. After that, PictureWriter doesn't contact it again unless you deactivate the license.
PictureWriter checks download.picturewriter.app for updates, which shares your app and macOS versions with that server, as any such check does.
Can I move my license to another Mac?
Yes. Choose License… in the PictureWriter menu and deactivate it, then activate the same key on the other Mac.
Which Macs does it run on?
PictureWriter requires macOS 14 or later and is designed for Mac computers with Apple silicon. Transitions and effects are processed on the GPU, so playback performance depends on your Mac's chip.
These results were measured on a MacBook Air with M4, testing each of the 194 transitions and effects on its own at 1080p:
- 1080p at 30 or 60 fps: M4 or later is recommended. A typical transition or effect renders in under 4 ms per frame, and 187 of the 194 render in real time at 60 fps.
- Demanding transitions: Contact Sheet and Rear Projection play at about 30 fps at 1080p.
- 120 fps: Requires a display with a 120 Hz refresh rate, such as a MacBook Pro with ProMotion or a compatible external display. On MacBook Air with M4, 151 of the 194 render in real time at 120 fps. A Mac with a Pro or Max chip is recommended for demanding transitions or multiple effects.
- 4K: 4K video has four times the pixels of 1080p and requires more GPU performance at any frame rate.
- Earlier Apple silicon chips: Supported. The viewer might drop frames when multiple effects are applied.
Playback performance doesn't affect exported videos. PictureWriter renders every frame during export.
Some features have additional requirements:
- Closed captions: Requires macOS 26 or later.
- Trailer Card and Computer Terminal: These transitions use Apple Intelligence, when available, to write their on-screen text. Otherwise, they use standard text.
