1. What is Frame Size?

Frame size refers to the amount of storage space required for a single frame in a video. It's determined by the resolution (width × height) and the color depth (bits per pixel).

2. How Does the Calculator Work?

The calculator uses the frame size formula:

Where:

• \( Width \) — Horizontal resolution in pixels
• \( Height \) — Vertical resolution in pixels
• \( Bit Depth \) — Color depth in bits per pixel
• 8 — Converts bits to bytes (8 bits = 1 byte)

Explanation: The formula calculates the uncompressed size of a single video frame in bytes.

3. Importance of Frame Size Calculation

Details: Knowing frame size helps estimate storage requirements, bandwidth needs, and processing power for video applications. It's essential for video encoding, streaming, and storage planning.

4. Using the Calculator

Tips: Enter the video resolution (width and height in pixels) and the bit depth (typically 8, 10, 12, or 16 bits). All values must be positive integers.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical bit depth for videos?
A: Most consumer videos use 8 bits per channel (24 bits total for RGB). High-end video may use 10 or 12 bits per channel.

Q2: Does this calculate compressed frame size?
A: No, this calculates uncompressed frame size. Actual MP4 frames are compressed and typically much smaller.

Q3: How does this relate to video file size?
A: Multiply frame size by frame rate and duration, then apply compression ratio to estimate file size.

Q4: What about color subsampling?
A: This calculator assumes full color resolution. Subsampling (like 4:2:0) would reduce the actual size.

Q5: Does this account for alpha channels?
A: No, for transparent video you would need to add additional bits for the alpha channel.
