Video Bitrate Calculator
Calculate video bitrate and file size based on resolution and quality
Quick Resolution Presets
Formula
Bitrate = Pixels × Frame Rate × Bits per Pixel × Codec FactorEstimate video bitrate and storage requirements for different quality settings
How to Use
- 1Select resolution — Choose your video resolution (1080p, 4K, etc.).
- 2Set frame rate — Select your target frame rate (24fps for cinema, 60fps for smooth motion).
- 3Choose quality — Select a quality preset based on your use case.
- 4Select codec — Choose your video codec (H.264 for compatibility, H.265 for smaller files).
Frequently Asked Questions
What bitrate should I use for YouTube?
YouTube recommends 8-12 Mbps for 1080p at 24-30fps, and 35-68 Mbps for 4K. Higher bitrates ensure better quality after YouTube re-encodes your video.
What is the difference between H.264 and H.265?
H.265 (HEVC) provides about 50% better compression than H.264, meaning smaller files at the same quality. However, H.264 has better compatibility with older devices and software.
How does frame rate affect file size?
Higher frame rates require more data. 60fps video is roughly twice the size of 30fps at the same quality. Consider whether the smoother motion is worth the extra storage.
What bitrate do I need for streaming?
For live streaming, use 4-6 Mbps for 1080p on Twitch, 3-6 Mbps for YouTube Live. Your upload speed should be at least 1.5x your streaming bitrate for stability.
Why is my exported file larger than calculated?
Actual file sizes vary based on video content complexity. Fast action and detailed scenes require more data. The calculator provides estimates based on average content.
