Video Resolution Formula:
From: | To: |
Video resolution refers to the number of pixels that compose an image on a display, typically represented as width × height. For a given megapixel count, the resolution depends on the aspect ratio of the display.
The calculator uses these formulas:
Where:
Explanation: The formula calculates the width first by accounting for the aspect ratio, then derives the height proportionally.
Details: Knowing the exact resolution helps in video production, camera selection, display compatibility checks, and ensuring optimal image quality for different screen sizes.
Tips: Enter the camera's megapixel value (typically found in specifications). The calculator will output the corresponding 16:9 resolution in width × height format.
Q1: Why use 16:9 aspect ratio?
A: 16:9 is the standard widescreen format for most modern displays, TVs, and online video platforms.
Q2: How does this differ from photo resolution?
A: Photos often use different aspect ratios (like 4:3 or 3:2). Video typically uses 16:9 or sometimes 1.85:1 for cinema.
Q3: What are common video resolutions?
A: Common resolutions include 1920×1080 (Full HD), 3840×2160 (4K UHD), and 7680×4320 (8K UHD).
Q4: Does higher megapixel always mean better video?
A: Not necessarily. Other factors like sensor size, pixel quality, and processing matter more than just megapixel count.
Q5: Can I calculate for other aspect ratios?
A: Yes, by adjusting the formula. Replace 16/9 with your desired width/height ratio (e.g., 4/3 for standard definition).
