1. What is Stream Bitrate?

Stream bitrate refers to the amount of data processed per unit of time in a video stream, typically measured in kilobits per second (kbps). It's a crucial factor in determining video quality and bandwidth requirements.

2. How Does the Calculator Work?

The calculator uses the bitrate formula:

Where:

• \( FPS \) — Frames per second
• \( Resolution \) — Total number of pixels per frame
• \( Compression \) — Compression factor (typically between 0 and 1)

Explanation: The equation calculates the theoretical bitrate by multiplying the frame rate by the resolution and compression factor.

3. Importance of Bitrate Calculation

Details: Accurate bitrate estimation is essential for streaming quality, bandwidth planning, and ensuring smooth playback without buffering.

4. Using the Calculator

Tips: Enter FPS (typically 24-60 for video), resolution (width × height in pixels), and compression factor (varies by codec). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical compression factor?
A: Modern codecs like H.264/AVC might use 0.07, while H.265/HEVC could use 0.05, but this varies by content and settings.

Q2: How does resolution affect bitrate?
A: Higher resolutions (like 4K vs 1080p) dramatically increase bitrate requirements as they contain more pixels per frame.

Q3: Why is FPS important in bitrate?
A: More frames per second means more data needs to be transmitted each second, increasing the bitrate linearly.

Q4: What's the difference between bitrate and bandwidth?
A: Bitrate refers to the data rate of the stream itself, while bandwidth is the network capacity available to carry that stream.

Q5: How can I reduce required bitrate?
A: You can lower FPS, reduce resolution, or use more efficient compression (better codec or higher compression ratio).
