1. What is Video Size Calculation?

The video size calculation estimates the storage space required for a video file based on its bitrate and duration. This is essential for storage planning and bandwidth considerations.

2. How Does the Calculator Work?

The calculator uses the video size formula:

Where:

• \( Bitrate \) — Video bitrate in kilobits per second (kbps)
• \( Length \) — Video duration in seconds
• 8 — Converts bits to bytes
• 1024 — Converts kilobytes to megabytes

Explanation: The formula calculates the raw data size by multiplying bitrate by duration, then converts it to megabytes.

3. Importance of Video Size Calculation

Details: Knowing video size helps in storage planning, bandwidth allocation, and ensuring compatibility with various platforms and devices.

4. Using the Calculator

Tips: Enter bitrate in kbps and length in seconds. Common bitrates: 1500 kbps (SD), 4000 kbps (HD), 8000 kbps (Full HD), 15000+ kbps (4K).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between kbps and KB/s?
A: 1 KB/s = 8 kbps. kbps measures bits, KB/s measures bytes. Internet speeds are often in bits, while file sizes are in bytes.

Q2: How does audio affect total file size?
A: This calculator shows video size only. For total size, add audio size (audio bitrate × duration / (8 × 1024)).

Q3: Why is my actual file size different?
A: Actual sizes may vary due to container overhead, variable bitrate encoding, or compression efficiency.

Q4: How to estimate bitrate for quality?
A: As rule of thumb: 1 Mbps for SD, 5 Mbps for 1080p, 15+ Mbps for 4K. Higher for less compression.

Q5: How to calculate for hours of video?
A: Convert hours to seconds (×3600) or use our calculator with length in seconds (e.g., 2 hours = 7200 seconds).
