Frequently Asked Questions
How much storage does 1 hour of 4K video take?
A 1-hour 4K video at 30fps using H.264 takes approximately 22–33 GB depending on bitrate settings. HEVC can reduce this by ~40%.
What bitrate do I need for 1080p streaming?
For 1080p at 30fps, a bitrate of 4,500–6,000 Kbps (H.264) is recommended. At 60fps, aim for 6,000–9,000 Kbps.
Is HEVC better than H.264 for streaming?
HEVC (H.265) offers ~40% better compression than H.264 at similar quality, meaning smaller files and lower bandwidth. However, encoding is slower and some older devices lack hardware decoding support.
Calculate by Resolution & Frame Rate

|---|---|---|---|---|
| 720p (HD) | 720p/24fps | 720p/30fps | 720p/60fps | 720p/120fps |
| 1080p (Full HD) | 1080p/24fps | 1080p/30fps | 1080p/60fps | 1080p/120fps |
| 1440p (2K) | 1440p/24fps | 1440p/30fps | 1440p/60fps | 1440p/120fps |
| 4K (2160p) | 4k/24fps | 4k/30fps | 4k/60fps | 4k/120fps |
| 8K (4320p) | 8k/24fps | 8k/30fps | 8k/60fps | 8k/120fps |
