The Mac app for sending large video files to clients

How to send large video files to clients — the videographer version

Search that phrase and you get the same list every time: WeTransfer, Dropbox, Google Drive, maybe a Vimeo link. All of them genuinely work, and for pro-to-pro handoffs — footage to a second editor, a rough cut to a planner — a plain transfer link is still the right call. We use one for that ourselves.

But a finished wedding film is not a handoff, and at wedding sizes the cracks show. A multi-gigabyte export through a browser tab is an upload you babysit: the tab has to stay open, sleep kills it, and a hiccup at 96% sends you back to zero. And the couple’s side is worse — they receive a download, not a delivery, and the film of their life lands in a Downloads folder next to the tax PDFs.

The honest answer splits the question in two. Move working files with a transfer tool; deliver the finished film with something built to be watched. The Mac app handles the first half — getting the huge file up without drama — and the gallery it feeds handles the rest.

An upload that survives a restart

Drag the export into the app and it streams up in small confirmed chunks, tracking exactly how much has safely landed on the other side. Wi-Fi drops? It resumes. The Mac sleeps? It picks back up on wake. Quit the app — or restart the whole machine mid-file — and the queue is rehydrated on the next launch and continues from the last confirmed byte, not from zero.

That changes how delivery day feels. You start the queue and go edit something else, instead of nursing a progress bar and praying the connection holds. We push finished weddings through this exact app every week on ordinary studio broadband; the upload is a thing you start, not a thing you watch.

Not a one-way chute

The app is the studio side of Knotflix, not just an upload box. Your weddings sit in a sidebar and each one opens as a set of cards — films and photographs side by side — so a wedding with four thousand photographs still shows you its films at a glance. Set one up for Saturday, drag the films onto a card, drop the photo sets onto another.

Everything you have delivered stays browsable, and every delivered film comes back down as easily as it went up — pull a wedding onto a new machine without digging through archive drives. What comes back is the 1080p MP4 we stream from, not your graded export, so keep that on your own drives. Delete is there too, for the test uploads and the wrong-version moments.

What the couple gets on the other end

The part that makes the upload worth it: your couple never sees a file transfer. They open a private link — no account, nothing to install, and no password unless you add one — and the film streams in HD on a dark, premiere-style page with your studio’s name on it. Parents get the same link forwarded and it just plays.

The film is downloadable as well as streamable — a high-quality 1080p MP4, for the couple and for you, with nothing to switch on beforehand and no window it expires in. Your graded export stays your archive master; this is the delivery, not the vault. Every gallery includes 90 days of hosting; when a couple extends it, half of every extension is paid out to your studio through Stripe.

Notarized, native — and honest about the limits

The app is Developer ID-signed and Apple-notarized, so it installs like serious Mac software should: no Gatekeeper warnings, no right-click-to-open ritual, on your machine or a teammate’s.

The limits, plainly: it needs an Apple silicon Mac — an M1 or later — and it comes with the Studio plan. On an Intel Mac, on Solo, or on Windows you upload through the browser or connect Dropbox and import from there, and both feed exactly the same galleries. What you give up without the app is the restart-proof resumable queue, not any part of the delivery.
