The Best Way to Send 4K Video Footage to Clients and Editors

A single minute of 4K footage can outweigh an entire wedding album of photos. If you shoot or edit video for a living, you already know the pattern: the shoot wraps, the client or editor needs the files yesterday, and your transfer tool either rejects the upload, compresses it into mush, or dies at 87% and starts over from zero.

Sending 4K footage isn't hard once you understand what actually matters in a transfer tool — and what's just marketing. This guide breaks down the real file sizes you're dealing with, why most tools choke on them, and a delivery workflow that gets footage to editors and clients without drama.

How big is 4K footage, really?

File size comes down to bitrate, not resolution alone. A quick reference for UHD footage by codec and recording bitrate:

• Consumer 4K (H.264/H.265, 60–100 Mbps): roughly 450–750 MB per minute
• High-bitrate mirrorless / 10-bit log (200–400 Mbps): roughly 1.5–3 GB per minute
• ProRes 422 (UHD, ~470 Mbps): about 3.5 GB per minute
• ProRes 422 HQ (UHD, ~700 Mbps): over 5 GB per minute

Do the math on a real shoot and the numbers escalate fast: a ten-minute ProRes HQ interview is 50+ GB, and a full day of multi-cam b-roll can fill a terabyte. (If you're curious what a terabyte actually holds, we broke it down in how much is 1 TB of storage.) This is why tools designed for sharing documents fall apart the moment video enters the workflow.

Why most transfer tools choke on 4K

• Hard size ceilings. Free tiers built around documents and photos hit their limits at a fraction of one ProRes clip.
• Fragile uploads. A 60 GB upload over hotel Wi-Fi will hiccup at some point. If the tool can't resume, every hiccup means starting over.
• Silent recompression. Some sharing and messaging platforms re-encode video to save bandwidth — fatal when an editor needs your master files bit-for-bit.
• Links that expire too soon. Editors don't always download the day you send. A link that dies in 48 hours guarantees a re-send request.
• No confirmation. Without download notifications you're left messaging "did you grab the files?" while the deadline ticks.

What actually matters when sending video files

Strip away the feature lists and three things determine whether a transfer tool works for 4K delivery:

• Chunked, resumable uploads — large files are uploaded in pieces, so a dropped connection resumes where it left off instead of restarting
• Zero compression — the recipient gets the exact bytes you uploaded, checksums and all
• Headroom and control — generous size limits, custom expiry dates, and download notifications so multi-gigabyte handoffs don't need babysitting

Everything else — previews, branding, analytics — is workflow gravy. Useful gravy, as you'll see below, but those three are non-negotiable.

A footage delivery workflow that scales

Organize by project, not by transfer

Treat each job as a project with clearly named folders — CAM-A, CAM-B, AUDIO, GRADED — before anything leaves your machine. EveryTransfer's projects feature lets you keep every transfer for a client job grouped together, so three weeks later you're not hunting through your sent history for "the link with the drone shots."

Send a link, then let notifications do the chasing

Send one link per delivery and switch on download notifications — by email, or piped straight into Slack, Discord, or Telegram where your team already lives. The moment your editor grabs the files, you know. If download analytics show the link untouched the day before a deadline, that's your cue to nudge — with evidence, not vibes.

Use previews for review, proxies for editing

In-browser file previews let a client or director check a clip without downloading 40 GB first — perfect for "is this the right take?" moments. For the edit itself, pair full-resolution masters with proxy files: small, low-bitrate copies your editor can cut with immediately while the masters finish transferring. Proxies complement a good transfer tool; they don't replace sending the real files for the final conform and grade.

How to send 4K footage with EveryTransfer

1. Open everytransfer.com and drag in your footage folders. Short clips and cutdowns fit under the 1 GB no-account limit; for full shoots, sign in and check the plans page for the limits that fit your volume.
2. Let chunked, resumable uploads run. Start the upload and walk away — if your connection drops overnight, it resumes instead of restarting.
3. Set the expiry to match your production schedule. Give editors a realistic window with a custom expiry date, and add a password or download limit for sensitive client work.
4. Send the link to everyone who needs it. One link serves the editor, the colorist, and the client — recipients never need an account.
5. Watch the notifications roll in. You'll get a ping per download, and analytics show exactly who pulled the files and when.

Files transfer exactly as uploaded — no recompression, no "optimized for web" surprises — which is the entire point when the recipient is conforming your masters. For a broader look at video-sharing options beyond client work, see how to send a large video online.

Frequently Asked Questions

How long does it take to upload 100 GB of footage?

At a sustained 100 Mbps upload speed, 100 GB takes roughly two and a half hours; at 20 Mbps it's eleven hours or more, and on gigabit fiber it can finish in about fifteen minutes. The number that matters is your upload speed, which is often a fraction of the download figure your ISP advertises — run a speed test before promising a delivery time. Resumable uploads make slow connections survivable: kick the transfer off at wrap and let it run overnight.

Should I compress 4K footage before sending it?

No — not if the recipient needs editing-quality files. Video codecs are already heavily compressed, so zipping footage saves almost nothing while adding an unzip step, and re-encoding to a smaller codec throws away image data your colorist can never get back. The smarter play is proxies: send lightweight proxy files for immediate editing and the untouched masters alongside or right behind them.

Can I send the same footage to multiple people?

Yes — one transfer link works for as many recipients as you share it with, and none of them need an account. Upload once, send the link to your editor, colorist, and client, and use download notifications to confirm each person actually pulled the files. If you want to cap distribution, set a download limit on the transfer.

What upload speed do I need to deliver footage same-day?

For same-day delivery of a typical 50–150 GB shoot, you want at least 100 Mbps of sustained upload bandwidth. Below that, plan around it: start uploads during the shoot's last setup, deliver proxies first so the edit starts immediately, or upload from a location with fiber before heading home. Production houses on gigabit symmetric connections can treat even ProRes deliveries as a coffee-break job.

Stop babysitting your file transfers

4K delivery comes down to a tool that respects the size of your files: chunked uploads that survive bad Wi-Fi, zero compression, expiry dates you control, and a notification the moment your editor hits download. Set that up once, and "sending the footage" stops being a line item in your schedule.
