Keeping a project portable between machines
You open a video project on another Mac and half the clips are missing, the fonts have changed and the music is offline. Here is why editing projects break when they move, and the habits that let you pick up work anywhere.
You start an edit on your desk Mac and want to finish it on a laptop. You copy the project file across, open it, and are greeted by red "media offline" frames, missing fonts and a music track that no longer plays.
The project file moved. The things it depends on did not.
Why projects break when they move
Most video editing projects are not videos. They are instructions: take this clip from this location, trim it from here to here, place it at this point on the timeline, put this text over it in this font. The media itself usually lives elsewhere.
When the project moves to another machine, any instruction that points somewhere that does not exist there fails:
Absolute paths. "The clip at /Users/you/Desktop/Shoot/clip04.mov." On another Mac, with another user name or another folder layout, that path is wrong.
External drives. Footage on a drive named Media SSD is found only when a drive with that name is connected — and the folder structure on it matches.
Photos library media. Clips added from the Photos library may be referenced in a way that only works on the Mac where that library lives.
Fonts. Text styled in a font installed on one Mac appears in a fallback font on another where it is not installed.
Music and sound effects downloaded to one machine's Downloads folder, or licensed to one account.
Cloud placeholders. Files in iCloud Drive or another cloud folder that are listed but not downloaded to this Mac. The project sees a file that is not actually there yet.
Habits that keep projects portable
One folder per project. Keep the project file, the footage, the audio, the images and any fonts or assets together in one folder:
2026-10-07_product-demo/
├── project
├── footage/
├── audio/
├── images/
└── exports/
Copy the folder and everything travels together.
Import from the project folder. Before adding a clip, copy it into the project folder, then import it from there. Importing directly from the Desktop, Downloads or a camera card creates dependencies on those places.
Stick to common fonts, or carry them. Use system fonts where you can. If you use a custom font, keep its file in the project folder — within the terms of its licence — and install it on the other machine.
Download cloud files fully. If the project lives in a cloud folder, make sure every file is downloaded before opening the project on another machine. On a Mac, right-click the folder and choose the option to keep it downloaded, if your cloud service offers one.
Close the project before moving it. Copying a project while it is open can capture a half-saved state.
Test the move before you depend on it. Copy the project folder to the other machine and open it before you leave the first one behind.
When media goes missing anyway
- Find the missing file on the new machine and put it in the location the project expects, or
- use the editor's relink function, if it has one, to point the project at the file's new location.
Relinking one clip is easy. Relinking two hundred, one by one, is the cost of skipping the habits above.
The exported video is the safest copy
A finished export — MP4 or MOV — is self-contained. It plays anywhere, on any machine, forever. Keep one alongside the project, even for unfinished work: if the project breaks, the last export shows exactly what it looked like.
Portable between Mac and iPhone?
Moving a project between a Mac and an iPhone or iPad adds another layer: the other device needs a compatible editor, enough storage for the media, and a way to receive the files. The same rule applies — keep everything in one place, and move it together.
What Garfi does
Garfi Video Editor saves projects as portable .gvideo packages — a single item in Finder that you can save, reopen and move with the system file browser or a compatible cloud drive. Keeping the project as one package, rather than a file plus scattered references, is designed for exactly the kind of move this article describes.
The good habits still apply: keep source footage organised, let cloud files download fully before opening, and close the project before copying it. Editing, saving and reopening projects remain available whether or not you have bought the export unlock.
Garfi edits on a precise timeline with trim, split, speed from 0.25× to 4×, one picture-in-picture layer, text, editable automatic captions, music and voice-over, and exports MOV or MP4 in H.264 or HEVC, up to 4K when supported, without a watermark. The download is free with an export trial you start yourself; a one-time purchase unlocks export permanently. There is no account, developer cloud or generative AI.
