📹 Video Size Calculator — Smart Compression & Year-Optimized
Estimate video file size | Compare codec efficiency by model year | Real-time graph
🔹 Pixel resolution influences typical bitrate range, but file size relies on bitrate.
Typical USA streaming: 1080p @ 5-8 Mbps, 4K @ 15-35 Mbps.

📈 Advanced comparison: Current bitrate vs Year-efficiency optimized
*Optimized size uses codec efficiency factor based on selected model year (same perceptual quality).
📌 Video size factors (global & USA reference)
• Bitrate: Higher bitrate = larger file & better quality. USA streaming services: Netflix recommends 5 Mbps for 1080p, 15 Mbps for 4K.
• Resolution: More pixels need higher bitrate for clarity. Global standards: 1080p (Full HD), 4K widespread in EU/ASIA.
• Frame rate: 24/25/30/50/60 fps – 60 fps doubles data vs 30 fps at same bitrate if using constant quality, but bitrate entry covers final.
• Codec/Year factor: Modern codecs (AV1, H.265) reduce size 35–55% vs H.264 for equal subjective quality. This calculator shows “optimized size” based on model year.
• Audio bitrate: Stereo 128–192 kbps (AAC) standard. 5.1 surround up to 448 kbps.
• Bitrate: Higher bitrate = larger file & better quality. USA streaming services: Netflix recommends 5 Mbps for 1080p, 15 Mbps for 4K.

🧭 How to use this video size calculator
- 1. Choose Resolution preset or define custom width/height (info reference).
- 2. Set frame rate, video bitrate (Mbps), audio bitrate & duration.
- 3. Enter Model Year (e.g., 2024, 2025, 2026). The calculator automatically maps the optimal codec efficiency factor (AV1 for 2024+).
- 4. Results update instantly: Actual total file size based on your bitrate + Optimized file size using modern compression (same visual quality).
- 5. Graph compares both sizes side-by-side — shows real savings. Great for planning storage & streaming budgets.
🎯 Expert tips for efficient video storage
- ✔ Match bitrate to content: fast action/sports benefit from higher bitrates (+30%), while static videos can use ~20% less.
- ✔ Leverage modern codecs: For archive, encode with AV1 (Year 2024+) to reduce file size up to 50% compared to H.264.
- ✔ Two-pass encoding improves efficiency without changing bitrate — great for VOD platforms.
- ✔ Audio optimization: Use AAC 96-128 kbps for podcasts, 192 kbps for music videos.
- ✔ Professional streaming (OBS recommendations): 1080p 60fps @ 6–8 Mbps, 4K 60fps @ 25–45 Mbps.
