1. What is Video Frame Size?

The video frame size represents the amount of memory required to store a single frame of video. It's calculated based 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:

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

Explanation: The equation calculates the raw uncompressed size of a video frame by multiplying all the components that contribute to its data size.

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 frame dimensions 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: Standard video is usually 8 bits per channel, while professional formats may use 10 or 12 bits.

Q2: Why divide bit depth by 8?
A: This converts bits to bytes (8 bits = 1 byte), since file sizes are typically measured in bytes.

Q3: How does this relate to video file size?
A: Total video size = frame size × frame rate × duration, minus any compression savings.

Q4: What about compressed video formats?
A: This calculates uncompressed size. Compression ratios vary by codec and settings.

Q5: How does this apply to different color spaces?
A: The calculation works for any color space - just adjust the channels parameter (e.g., 1 for grayscale, 3 for RGB, 4 for CMYK).
