1. What is a Video Bitrate Calculator?

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

Purpose: It helps video professionals and content creators determine the data rate needed for uncompressed video streams.

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 by multiplying all the factors that contribute to video data size.

3. Importance of Bitrate Calculation

Details: Proper bitrate estimation ensures high quality video, adequate storage planning, and proper bandwidth allocation.

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 for compressed or uncompressed video?
A: This calculates raw, uncompressed bitrate. Compressed video will have much lower bitrates depending on codec and settings.

Q2: What's a typical frame rate?
A: Common rates are 24 (film), 30 (NTSC), 60 (high motion), but this varies by application.

Q3: How does bit depth affect quality?
A: Higher bit depth (10-bit, 12-bit) allows more color information but increases file size.

Q4: How do I convert to megabytes?
A: Divide the result by 8 (bits to bytes) then by 1,048,576 (bytes to megabytes).

Q5: Does this include audio?
A: No, this calculates video bitrate only. Audio would be additional.
