Understanding Video File Sizes
Video files are massive. Understanding file sizes helps you choose the right transfer method.
Typical Video File Sizes
| 1 minute 1080p (YouTube quality) | 100-150 MB |
| 1 minute 4K (H.264) | 400-600 MB |
| 1 minute 4K (ProRes) | 5-8 GB |
| 1 minute RAW 4K | 20-50 GB |
| 10 minute 1080p video | 1-1.5 GB |
| 10 minute 4K video | 4-6 GB |
| 30 second 4K commercial | 2-3 GB (ProRes) |
| 1 hour 1080p movie | 6-10 GB |
As you can see, even short 4K clips can exceed email limits (25MB) and many free file sharing limits (2GB). Professional formats like ProRes or RAW are impossible to share through conventional means.

Should You Compress Video Before Sending?
💡 The Compression Decision
Never compress if: This is the master delivery, client specifically requested uncompressed, or it's for broadcast/archive.
Compress if: It's for review/approval, web upload, or client just needs to "see it".
Compression Options
H.264/H.265 (HEVC): Best compatibility, good compression
ProRes Proxy: Edit-friendly smaller files
DNxHR: Professional alternative to ProRes
Web-optimized MP4: Smallest for web delivery
Quick Compression Guide
- HandBrake: Free, excellent quality, slow
- Adobe Media Encoder: Professional workflows
- FFmpeg: Command-line power user tool
- Apple Compressor: macOS professional
For Video Professionals: Workflow Tips
Setting Client Expectations
Communicate clearly about:
- Delivery format (compressed vs. original)
- Expected file sizes
- Download requirements (speed, storage space)
- Expiry times for temporary links
Organizing Deliverables
Professional file naming and organization:

Backup Strategy
Never rely solely on transfer links:
- Keep local copies until client confirms receipt
- Use cloud storage for archive (Backblaze, Wasabi)
- Consider LTO tape for long-term archival
Pro Tips for Sending Video Files
Before You Send
- Check client can receive large files (corporate firewalls often block)
- Confirm they have enough storage space
- Test your upload speed (speedtest.net)
- Consider time zones (upload overnight for faster speeds)
- Use wired connection, not WiFi, for large uploads
During Transfer
- Don't close the browser tab during upload
- Disable sleep mode on your computer
- Consider upload accelerators for very large files
- Monitor progress and have backup plan
After Sending
- Send download instructions to recipient
- Include expected file size and format
- Request confirmation of successful download
- Keep files until confirmation received
Conclusion
