如何计算Video Resolution Converter
learn.whatIsHeading
Converts between common video resolutions (480p, 720p, 1080p, 4K) and shows pixel counts and file size estimates.
公式
File size = resolution × frame rate × bit depth × duration
分步指南
- 1Standard resolutions have fixed pixel dimensions
- 2File size = resolution × frame rate × bit depth × duration
- 3Codec compression dramatically reduces actual file size
例题解析
输入
1080p video
结果
2.07M pixels
常见错误注意事项
- ✕Ignoring codec compression in file size estimates
- ✕Confusing resolution with quality (bitrate matters too)
常见问题
How much storage does 4K video use?
Roughly 375 MB/minute for H.265, or 750 MB/minute for H.264.
