How to send large video files to clients

To send a large video file to a client, skip email (it compresses and caps at ~25 MB) and use a file transfer: upload the export as-is, ideally as an MP4 for compatibility, and share the single download link. Files up to 50 GB go in one transfer, no ZIP-splitting, no quality loss. Here's how to do it well, and how to make sure you get paid for it.

Why big video is a pain

Video files are big, and the usual tools fight you on it. Email bounces anything over ~25 MB. Messaging apps crush the quality. Cloud-drive links work but bury the file in folders and permissions the client has to navigate. And splitting a 4K export into ZIP chunks is a recipe for a corrupted download and a confused client.

What you actually want is simple: the client clicks one link and gets the exact file you exported, at full quality, with nothing to install. That's what a proper transfer does.

Pick the right format

Before you send, make sure you're sending the format the client can actually use:

• MP4 (H.264) for delivery. It plays everywhere, browsers, phones, TVs, social platforms, with no codec faff. This is the safe default for a final the client just needs to watch or post.
• MOV / ProRes only if they're editing. Big, high-quality masters are right for an editor or colourist, but they choke consumer players and Windows machines. Don't send a ProRes master to a client who just wants to review the cut.
• Convert if needed. If your export is a MOV the client can't open, you can convert MOV to MP4 (or any other pair) in the same step as sending it, see video conversion.

Send it in one link

Drop the file in, get a link, share it. No account needed for the person receiving it. On FileFlippers a single transfer holds up to 5 GB free, 25 GB on Pro, and 50 GB on Squad, so even a long 4K piece goes in one go, see large file transfer. The upload is chunked and resumable, so a dropped connection mid-upload doesn't cost you the whole thing.

Expiry and quality

Two things worth setting before you hit send:

• Expiry. Pick how long the link lives, from a 15-minute self-destruct up to 60 days. For a client deliverable, a week or two is usually right, long enough for them to grab it, short enough that old links don't pile up.
• Quality. The transfer sends the exact bytes you uploaded, no re-compression. So the quality the client gets is the quality you exported. If you need a smaller file, transcode it once to a high-bitrate MP4 yourself rather than letting some tool quietly downscale it.

If it's a paid deliverable

If this video is the final, paid piece of work, the handover is also the riskiest moment to get paid, once the client has the file, your leverage is gone. The fix is to make payment the thing that releases it.

Send a watermarked preview the client can review and approve, and release the clean export only when they pay. That's what getting paid before you deliver is built around, and the money lands straight in your own Stripe account. No invoice to chase, because the download and the payment are the same step.
