1. What is Video Frame Size?

The video frame size represents the amount of memory (in bytes) required to store a single frame of uncompressed video. It depends on the resolution, color depth, and number of color channels.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( width \) — Frame width in pixels
• \( height \) — Frame height in pixels
• \( bit\_depth \) — Number of bits per color channel
• \( channels \) — Number of color channels (e.g., 3 for RGB)

Explanation: The equation calculates the raw storage needed for one frame by multiplying the total pixels by bytes per pixel (bit depth divided by 8) and then by the number of color channels.

3. Importance of Frame Size Calculation

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

4. Using the Calculator

Tips: Enter the frame dimensions in pixels, bit depth in bits (typically 8, 10, 12, or 16), and number of color channels (3 for RGB, 4 for RGBA). All values must be positive integers.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical frame size for HD video?
A: For 1920×1080 8-bit RGB: 1920×1080×(8/8)×3 = 6,220,800 bytes (about 6.2MB) per frame.

Q2: How does compression affect frame size?
A: Compression can dramatically reduce frame size (often by 90% or more), but this calculator shows uncompressed size.

Q3: What's the difference between bit depth and color depth?
A: Color depth typically refers to total bits per pixel (bit depth × channels), while bit depth is bits per channel.

Q4: How do I calculate video file size from frame size?
A: Multiply frame size by frame rate (frames per second) and duration (seconds).

Q5: What about YUV color space?
A: For YUV (common in video), you'd typically have different calculations due to chroma subsampling.
