How to send large video files without shrinking the master.
A finished 4K export will not fit in an email and often not in a free transfer link either. Here is what a large video file weighs, the six ways to move one, and which suits each job.
Do not attach it and do not compress it. Upload the file whole to a service that accepts its size, then send a link. For a colleague, a cloud drive. For a one-off under a couple of gigabytes, a transfer link. For a paying client, a delivery platform that presents the video and keeps the original ready to download.
Why it will not send
Video is measured in gigabytes. Email is not.
Gmail caps attachments at 25 MB and Outlook at 20 MB. Those limits were set for documents and photos. A 4K H.264 delivery export runs around 62 Mbps, which is about 0.47 GB a minute, so a one-minute teaser is roughly twenty times the Gmail limit.
A master is bigger again. 4K ProRes runs about 5.6 GB a minute, so a two-minute ProRes master is about 11 GB. When a post team asks for the master, you are moving tens of gigabytes.
Size is half the problem. The other half is the upload. A tool that sends a large file as one long request loses everything when the connection drops, and on a multi-hour upload over hotel wifi it will drop. That is why a big video keeps failing even where the size is allowed.
How big it is
Find the row that matches your export.
| Deliverable | Size |
|---|---|
| 1-minute teaser, 4K H.264 | 0.5 GB |
| 3-minute spot, 4K H.264 | 1.4 GB |
| 5-minute edit, 4K H.264 | 2.3 GB |
| 30-minute long-form edit, 4K H.264 | 14 GB |
| 2-minute 4K ProRes master | 11.2 GB |
| 3-minute 4K ProRes master | 16.8 GB |
| 5-minute 4K ProRes master | 28 GB |
| 500 to 800 image gallery, 5 to 8 MB JPEGs | 2.5 to 6.4 GB |
The six ways
Each one is right for something.
Google Drive takes files up to 5 TB and 750 GB of uploads a day, and Dropbox moves whatever you give it. For an editor or a colorist, a shared folder is a good answer. For a client it is a file browser and a download button, not a presentation of the work.
The free tier moves 3 GB a month across 10 transfers, links expire after 3 days, and it is for non-commercial use. Starter is $10 a month and Ultimate, $25 a month, takes the size ceiling off. Every plan is built to move a file and forget it.
Close to free and no size limit, and fine between post facilities. No client outside broadcast should be asked to install an FTP app and type credentials.
A host solves size and playback at once, but it re-encodes the file, carries its own player branding, and an unlisted link is open to anyone it is forwarded to. Right for reaching an audience.
Built for the revision loop, with timestamped notes and version stacks. The approved cut still has to leave for somewhere else to be delivered, and Frame.io has no embeds.
Up to 100 GB per file, uploaded whole. The client opens one link to a page under your studio name that plays the video at up to 4K when the source is 4K, with the original ready to download.
Vimeo’s storage is good value: Vimeo Starter is $12 a month billed annually for 2 TB. Removing Vimeo’s logo from the player takes the Standard plan, $25 a month billed annually or $41 a month billed monthly, so on the cheaper plans the client sees Vimeo’s name on your work.
The best way, by job
Pick the method by who opens the link.
A cloud drive. Both sides make video, presentation does not matter, and Drive or Dropbox moves the file with no friction.
A free transfer link. Do not overthink it, but do not build client work on links that expire in three days.
A delivery platform. The client opens a page that looks like your studio, plays smoothly, and is still there when they ask for it next year.
Vimeo or YouTube. Reach is the point, so accept the re-encode and the platform branding as part of the deal.
A review tool. Collect timecoded notes on each version, then deliver the approved cut somewhere built for delivery.
Studios that make video every week use FRGMT as video delivery for videographers: review on a React link, final delivery on a Cinema page, both from the same folder. The VidFlow comparison covers the other video-first option.
What breaks at each size
Match your file to the row.
| At | What gives out |
|---|---|
| 20 MB | an Outlook attachment |
| 25 MB | a Gmail attachment |
| 3 GB | the WeTransfer free monthly allowance |
| 100 GB | the FRGMT per-file ceiling |
| 750 GB | a Google Drive user’s uploads for the day |
| 5 TB | a single Google Drive file |
Why not compress
Shrinking the file to fit the tool is the wrong way round.
You set the bitrate and the codec at the quality the work deserves. Re-encoding the export to clear an upload limit changes the work to suit the pipe. Compression is lossy where clients notice: gradients band, shadows go blocky, fast movement smears. A second pass on an H.264 file compounds it.
A smaller web version alongside the original is a convenience. The mistake is making it the only version because the delivery tool could not take the real one.
When a big upload fails at 90%
A tool that uploads in one request throws a 28 GB master away when the wifi blips at 90%. FRGMT uploads in parts and records each one as it lands. If the tab closes or the connection drops, reopen the page in the same browser and pick the same file again: as long as the file has not changed, the upload resumes from where it stopped instead of starting over.
Where the file lives
Upload the master once. Deliver it four ways.
The same folder serves a review link, a client page and a shared folder of masters. Free includes 5 GB; Pro holds 1 TB, priced by storage alone, with no per-hour or per-transfer fees.

Questions
Sending large video files, answered.
How do I send video files that are too large?
Upload the file somewhere that accepts its full size and send a link instead of the file, because email stops at 25 MB on Gmail and 20 MB on Outlook while a single minute of 4K video is about half a gigabyte. A cloud drive suits a colleague; a delivery platform suits a paying client. Either way, the email carries the link.
What is the best way to send video footage to clients?
Send finished footage to a client through a delivery platform, which gives them one link that opens a page under your studio name, plays the video without a download, and keeps the original file ready to save for as long as you keep the delivery. Raw footage for an editor is better in a shared cloud drive folder.
How do I send big files to clients?
Put the files in one folder on a service that takes them whole, then send the client a single link to that folder, protected with a password and an expiry date if the work is private, so they can open it in any browser without an account and save everything in one download. FRGMT shared folders download as one archive with subfolders intact.
What is the largest size video that can be emailed?
The largest video you can attach to an email is 25 MB on Gmail and 20 MB on Outlook, which is a few seconds of 4K footage at a normal delivery bitrate, so no finished video fits in an email and every working method uploads the file elsewhere and emails a link to it. Gmail already does this automatically for larger attachments, through Drive.
What is the file size limit for Google Drive?
Google Drive accepts a single file of up to 5 TB, and each user can upload up to 750 GB a day, so file size is rarely the problem when you send video through Drive; the limits that matter are your storage plan and how the shared link looks to a client opening it. Once the daily allowance is used, uploads pause until the next day.
How do I send large video files without losing quality?
Send the export itself rather than a smaller copy of it, because quality is lost when a file is re-compressed to fit an upload limit, so choose a tool that accepts the file at its full size and keeps the original for download. FRGMT takes up to 100 GB per file, uploaded whole, and keeps the original exactly as uploaded.
