1. What is Video Frame Size?

The video frame size represents the amount of memory required to store a single frame of video. It depends on the resolution (width × height), color depth (bit depth), and number of color channels.

2. How Does the Calculator Work?

The calculator uses the frame size equation:

Where:

• \( width \) — Frame width in pixels
• \( height \) — Frame height in pixels
• \( bit\_depth \) — Bits per color channel (typically 8, 10, 12, etc.)
• \( channels \) — Number of color channels (typically 3 for RGB)

Explanation: The equation calculates the raw uncompressed size of a single video frame by multiplying the pixel dimensions with the bytes per pixel (bit depth divided by 8) and the number of color channels.

3. Importance of Frame Size Calculation

Details: Knowing frame size is essential for estimating storage requirements, bandwidth needs, and memory allocation for video processing applications.

4. Using the Calculator

Tips: Enter width and height in pixels, bit depth in bits (typically 8 for standard video), and number of channels (3 for RGB, 4 for RGBA). All values must be positive integers.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical bit depth for video?
A: Most consumer video uses 8 bits per channel, while professional formats may use 10 or 12 bits.

Q2: How does this relate to video file size?
A: File size depends on frame size multiplied by frame count, then reduced by compression ratio.

Q3: What's the difference between bits and bytes?
A: 1 byte = 8 bits. We divide by 8 in the formula to convert bits to bytes.

Q4: Why are channels important?
A: Each color channel (Red, Green, Blue) requires separate storage, multiplying the total size.

Q5: How does resolution affect frame size?
A: Doubling resolution quadruples frame size (2× width × 2× height = 4× size).
