When recording with your Mevo camera to a microSD card, the available recording time depends on your chosen quality setting and the bitrate you've configured. Since Mevo supports customizable bitrates, understanding how to calculate estimated recording time can help you plan ahead.
How to Calculate Estimated Recording Time
The calculation is simple:
For example, if you're using a 128GB card (which is ~128,000MB), and recording at 20Mbps:
- 128,000MB × 8 = 1,024,000 megabits
- 1,024,000 ÷ 20 = 51,200 seconds = 14.2 hours
This formula is helpful if you adjust your bitrate from the defaults in the Mevo app.
Standard Bitrate Reference
| Resolution | Typical Recording Bitrate | Streaming Range |
|---|---|---|
| 4K | 40 Mbps | Not supported for streaming |
| 1080p | 20 Mbps | 1.2–6 Mbps |
| 720p | 10 Mbps | 0.7–2 Mbps |
| 480p | 4.5 Mbps | 0.4–1.5 Mbps |
| 360p | 2.5 Mbps | 0.3–1 Mbps |
If you are livestreaming while recording, your stream will continue uninterrupted even if your microSD card fills up. However, your local recording will stop once space runs out.
Estimated Recording Times by Card Size (Default Bitrates)
These estimates assume default recording bitrates and may vary slightly based on video complexity.
| Quality | 16GB | 32GB | 64GB | 128GB | 256GB |
|---|---|---|---|---|---|
| 360p (2.5 Mbps) | ~14 hrs | ~28 hrs | ~57 hrs | ~114 hrs | ~228 hrs |
| 480p (4.5 Mbps) | ~8 hrs | ~16 hrs | ~33 hrs | ~66 hrs | ~132 hrs |
| 720p (10 Mbps) | ~3.5 hrs | ~7 hrs | ~14 hrs | ~28 hrs | ~56 hrs |
| 1080p (20 Mbps) | ~1.75 hrs | ~3.5 hrs | ~7 hrs | ~14 hrs | ~28 hrs |
| 4K (40 Mbps) | ~50 min | ~1.6 hrs | ~3.2 hrs | ~6.4 hrs | ~12.8 hrs |
Scene Complexity Affects Recording Time
- High-motion scenes (e.g. sports) use more bitrate, resulting in shorter recordings.
- Low-motion scenes (e.g. interviews) compress more easily and result in longer recordings.
Bitrate fluctuation is normal — Mevo automatically adjusts based on scene activity to balance quality and file size.
