Formula Used

1) Pixels per frame
Width × Height

2) Bits per pixel
Bit Depth × Sampling Multiplier

Sampling multipliers
RGB 4:4:4 = 3.0, RGBA 4:4:4:4 = 4.0, YCbCr 4:2:2 = 2.0, YCbCr 4:2:0 = 1.5, Grayscale = 1.0

3) Raw bits per frame
Pixels per Frame × Bits per Pixel

4) Raw video bitrate
Raw Bits per Frame × FPS × Streams

5) Effective video bitrate
Uncompressed mode: Raw Video Bitrate
Ratio mode: Raw Video Bitrate ÷ Compression Ratio
Target mode: Target Mbps × 1,000,000 × Streams

6) Total pipeline bitrate
(Effective Video Bitrate + Audio Bitrate) × (1 + Container Overhead) × (1 + Safety Margin)

7) Estimated file size
Total Pipeline Bitrate × Duration in Seconds ÷ 8

This model uses decimal storage units and decimal network units for straightforward planning.

FAQs

1. What does this tool estimate?

It estimates raw video throughput, effective compressed bitrate, audio contribution, storage consumption, and practical network headroom for a chosen recording or delivery setup.

2. Why is uncompressed video data rate so high?

Uncompressed video carries every pixel sample without codec reduction. Higher resolution, more frames, deeper bit depth, and richer color sampling push the bitrate upward very quickly.

3. What is the difference between ratio mode and target bitrate mode?

Ratio mode estimates bitrate from raw throughput divided by a compression factor. Target mode ignores that estimate and uses the bitrate you specify directly for planning.

4. How does chroma subsampling affect results?

Subsampling reduces color detail samples relative to luma samples. That lowers bits per pixel, which lowers raw throughput and can significantly reduce required storage.

5. Why might actual file sizes differ from the estimate?

Real files vary because of codec efficiency, scene complexity, GOP structure, metadata, subtitles, variable bitrate behavior, encoder settings, and muxing overhead.

6. Should I use a safety margin?

Yes. A safety margin helps when bandwidth fluctuates, metadata grows, or project conditions change. It is especially useful for live delivery and storage provisioning.

7. Can I use this for livestream planning?

Yes. Enter your expected target bitrate, audio rate, overhead, and safety margin. The recommended network headroom helps you judge whether the link is comfortably sized.

8. Does this support HDR, alpha, or multi-camera planning?

Yes in a planning sense. Increase bit depth for HDR-style workflows, choose RGBA for alpha-heavy media, and raise the streams field for multi-camera totals.
