How do I deliver a 20GB video to a client?

To deliver a 20GB video to a client, upload it once to a video delivery platform and send the client a link that streams the film and offers the original file as a download. Never try to email it or split it into parts.

Files at this size expose the weaknesses of consumer tools. Free transfer services cap out well below 20GB or expire in a week. Cloud drives will upload it, but the client gets a low-quality preview, a "file too large to preview" message, or a zip that fails halfway. And a raw folder listing does nothing to make a 20GB master feel like a finished product.

A delivery platform handles the size properly: resumable uploads from your side, a transcoded streaming copy so the client can watch immediately, and a direct download of the full 20GB original when they want it.

On DLVRD there is no per-file ceiling that a normal deliverable will hit. Your storage allowance is the only limit (500GB on Basic, 1TB on Pro, 3TB on Studio), so a 20GB wedding film or brand spot is routine.
