1. What is a Recording Bitrate Calculator?

Definition: This calculator estimates the required bitrate for digital video recording based on resolution, frame rate, and bit depth.

Purpose: It helps videographers, streamers, and content creators determine the appropriate bitrate for their recording settings.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( BR \) — Bitrate (bits per second)
• \( W \) — Width in pixels
• \( H \) — Height in pixels
• \( F \) — Frame rate (frames per second)
• \( B \) — Bit depth (bits per pixel)

Explanation: The formula calculates the raw data rate before any compression is applied.

3. Importance of Bitrate Calculation

Details: Proper bitrate estimation ensures high-quality recordings without wasting storage space or bandwidth.

4. Using the Calculator

Tips: Enter the video width and height in pixels, frame rate (default 30 fps), and bit depth (default 8 bits). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Is this the actual file size?
A: No, this is the uncompressed bitrate. Actual file sizes will be smaller due to compression.

Q2: What's a typical bit depth?
A: Most consumer video uses 8-bit depth, while professional workflows often use 10-bit.

Q3: How does compression affect this?
A: Compression can reduce the actual bitrate by 10-100x depending on codec and settings.

Q4: What about audio bitrate?
A: This calculator only covers video. Audio bitrate must be calculated separately and added.

Q5: How do I convert to megabytes?
A: Divide the result by 8 to get bytes, then by 1,048,576 to get megabytes per second.
