How to send a large video file to a client
For a one-off transfer a file-sharing service or shared folder is fine, but for delivering a film to a client the best approach combines HD streaming that plays instantly on phones and TVs with a full-quality original available for download and archiving.
6 minUpdated
A 20-minute wedding film in 4K can easily be 10 to 30 GB. Email caps attachments at a few dozen megabytes, messaging apps crush the quality, and many clients do not know what a ZIP is. The real question is not how to send the file, but how the client can watch and keep it without hassle.
How big is a video file
| Version | Approx. bitrate | 10 minutes | 60 minutes |
|---|---|---|---|
| 4K master (high quality) | 100 Mb/s | ≈ 7.5 GB | ≈ 45 GB |
| 4K H.264 delivery | 40 Mb/s | ≈ 3 GB | ≈ 18 GB |
| 1080p H.264 delivery | 15 Mb/s | ≈ 1.1 GB | ≈ 6.8 GB |
| 720p streaming | 3–5 Mb/s | ≈ 0.3 GB | ≈ 1.8 GB |
Your options and their trade-offs
File transfer services (WeTransfer and similar)
Simple and no account needed. But free tiers cap file size, links expire after days, and the client must download the whole file before watching.
Google Drive, Dropbox, OneDrive
Links do not expire, but files eat your storage, in-browser previews are often low quality or unavailable while processing, and the interface looks like a file manager, not a gift.
YouTube or Vimeo
Great streaming and TV support, but YouTube adds compression, ads and other people’s recommendations, unlisted videos are open to anyone with the link, and viewers cannot download the original.
A client video gallery
A gallery built for delivery combines both: the film plays immediately in HD on a branded page, and a download button gives the full-quality original. You control access with a password and an expiry date, and photos, trailers and extra clips can live in the same place.
Why streaming is better for clients
- It plays immediately, with no 20 GB download first.
- Adaptive streaming (HLS) adjusts quality to the connection, so it does not stall on weaker internet.
- It works on phones, tablets and computers with no codecs to install.
- It casts to a TV via Chromecast or AirPlay.
- Family members just open a link.
The original still matters as the archive copy that will look good on future screens. Captures, for example, streams films in Full HD (1080p, plus 360p for weak connections) and keeps the original, up to 4K, available for download.
Codecs: H.264 or HEVC (H.265)
| H.264 (AVC) | HEVC (H.265) | |
|---|---|---|
| Compatibility | Virtually everywhere, including older TVs | Newer devices; some PCs and browsers need extra support |
| File size | Larger for the same quality | Roughly 30–50% smaller |
| Use it for | Safe client delivery | Archives, or clients with newer devices |
If you do not know what the client will watch on, deliver H.264 MP4 with AAC audio. ProRes and similar formats are for editing, not for clients.
Watching on a TV
- Cast from the gallery with Chromecast or AirPlay, no download needed.
- USB stick: H.264 MP4 with a simple file name; format the stick as exFAT for files over 4 GB.
- Smart TV browser: works, but is often slow; casting is almost always easier.
A recommended delivery flow

FAQ
How do I send a 20 GB video?
Use a file transfer service with a high enough limit, a shared cloud folder or a video gallery. For clients, a gallery with streaming and original download works best.
Why does video look bad on WhatsApp?
Messaging apps compress video heavily to save bandwidth. Send a link to the original or a streaming gallery instead.
What video format is best for TVs?
MP4 with H.264 video and AAC audio. It plays on almost every TV, including from USB.
Is HEVC better than H.264?
HEVC gives similar quality at a smaller size, but older devices may not play it. H.264 is the safer delivery choice.
Is 720p good enough for a wedding film?
For streaming on phones and most screens 720p looks good and does not stall. Keep the full-resolution original available for download.

Video delivery
The easiest way to send a video to a client is a video gallery: they watch the film instantly in HD on a phone or TV without downloading gigabytes, and the full-quality original (up to 4K) is there to download whenever they want.
Delivering wedding photos
A good wedding delivery has five steps: cull, edit within the agreed timeline, send a sneak peek within days, deliver an online gallery with web-size and full-resolution files, and run a structured album selection. Behind it all: at least two backup copies of the originals and a clear retention period.
How much an online gallery costs
Online client galleries cost anywhere from free to about 50 dollars or euros a month. For a photographer shooting 20–40 weddings a year a realistic budget is 10–25 a month, but the real difference between platforms is what that money buys: storage, video and whether they take a commission.
Archiving and data protection
Keep originals for as long as your contract promises (usually one to several years), in at least three copies on two different media, one of them off-site. Photos of people are personal data, so in Serbia they fall under the Law on Personal Data Protection (ZZPL), which closely follows the EU GDPR.
