1 GB is the threshold for near-lossless H.264 compression of long 4K recordings. At this size, multiple hours of 1080p or 30–60 minutes of 4K footage can be stored with no perceptible quality difference from the uncompressed original. 1 GB is a common ceiling for broadcast media ingest pipelines that accept H.264 proxies, many cloud storage sync tools, and high-quality video archive workflows where storage space still matters.
When you need 1 GB
- Long 4K recordings at near-lossless quality
30–60 minutes of 4K drone footage, documentary recordings, or conference video compresses to under 1 GB at CRF 18–20 with negligible quality loss.
- Proxy files for editing workflows
Editors working with 50–200 GB RAW camera files create 1 GB proxy files for smooth editing, then link back to originals for final export.
- Broadcast-ready H.264 deliverables
Broadcasters and streaming platforms often require H.264 MP4 deliverables under specific file size thresholds. 1 GB covers most 30-minute programmes.
Frequently asked questions
At 4K (3840×2160) with CRF 23, approximately 20–30 minutes of typical footage compresses to under 1 GB. Fast-moving content (sports, action) fits less — around 10–15 minutes. For longer 4K clips, use CRF 26–28 or split the footage into segments.
Yes — H.265 achieves the same visual quality at roughly half the file size. A 4K clip that takes 1 GB at H.264 CRF 23 takes approximately 500 MB at H.265 CRF 26. The trade-off is that H.265 playback requires a modern device (iPhone 6s+, recent Android, Windows 10 with HEVC codec).
Never. All compression runs in your browser using ffmpeg.wasm — a full video processing engine compiled to WebAssembly. Your files never leave your device. ConvertYard's servers only deliver the tool code — they never see your files.
