Example Data Table

Profile	Resolution	FPS	Codec	Compression Ratio	Estimated Delivery Bitrate	Estimated GB/Hour
Office Webinar	1920 × 1080	30	H.264	100:1	8.270 Mbps	3.721 GB
4K Event Stream	3840 × 2160	60	HEVC	180:1	52.950 Mbps	23.828 GB
Mobile Lesson Feed	1280 × 720	30	VP9	120:1	2.159 Mbps	0.972 GB
High Detail Monitor Wall	2560 × 1440	60	AV1	140:1	30.990 Mbps	13.946 GB

These rows demonstrate typical estimates. Actual numbers depend on scene complexity, encoder tuning, GOP structure, and delivery protocol overhead.

Formula Used

1) Bits per pixel
Bits per Pixel = Color Depth × Chroma Factor

2) Raw video bitrate
Raw Bitrate (bps) = Width × Height × Frame Rate × Bits per Pixel

3) Estimated compressed video bitrate
Estimated Video Bitrate = (Raw Bitrate ÷ Compression Ratio) × Codec Factor × Motion Factor × Dynamic Range Factor

4) Total payload bitrate
Total Payload Bitrate = Estimated Video Bitrate + Audio Bitrate

5) Delivery bitrate
Delivery Bitrate = Total Payload Bitrate × (1 + Overhead % ÷ 100)

6) Storage per hour
GB per Hour = Delivery Bitrate × 3600 ÷ 8 ÷ 1000

7) Reverse resolution estimate
Available Video Bitrate = (Target Delivery Bitrate ÷ (1 + Overhead % ÷ 100)) − Audio Bitrate

Max Pixels per Frame = (Available Video Bitrate × Compression Ratio ÷ Combined Factors) × 1,000,000 ÷ (Frame Rate × Bits per Pixel)

Frequently Asked Questions

1) What does this calculator estimate?

It estimates video bitrate, storage usage, bandwidth demand, safe link budget, and practical stream resolution under different codec, frame rate, and transport settings.

2) Why is compression ratio important?

Compression ratio controls how much the raw stream is reduced. Higher ratios lower bandwidth needs, but excessive compression can reduce clarity and introduce visible artifacts.

3) Why does motion complexity change bitrate?

Fast motion, sports, and noisy scenes usually require more bits to preserve detail. Low motion scenes compress more efficiently and need less bitrate.

4) Does audio really matter in total bandwidth?

Yes. Audio may be smaller than video, but it still adds to total payload size. It becomes more noticeable in low bitrate streams.

5) What is transport overhead?

Transport overhead represents protocol and packetization cost from streaming delivery. Headers, retransmissions, and encapsulation can increase real network usage above pure media bitrate.

6) Can this replace encoder testing?

No. It is a planning tool. Real encoders vary by preset, GOP design, content type, and rate control behavior, so final validation should still be tested.

7) Why does the reverse mode return a common resolution?

The tool first estimates the mathematical maximum frame size, then compares it with common display formats to show a practical, easy-to-use target.

8) Which codec factor should I choose?

Choose the codec closest to your deployment. AV1 and HEVC usually need less bitrate than H.264 for similar quality, while older formats often need more.
