The amount of storage you need is dependent not only on the settings you are using but also on the amount of recording that is being done. As a place to start, the average 2-hour movie on a DVD uses between 2 and 3 Gigabytes of data. While you may not be recording at the quality of a cinematic film, you do want to optimize the balance between storage and quality. The chart below can help to guide you when selecting an appropriate video quality for your storage and recording needs.
How Much Storage do I Need?
Presentation Storage Requirements
| Resolution | Bitrate | MB/Minute | MB/hour |
|---|---|---|---|
| 400x224 | 200 Kbps | 2.5 | 150 |
| 400x224 | 400 Kbps | 4.0 | 240 |
| 640x360 | 700 Kbps | 6.2 | 372 |
| 640x360 | 1.2 Mbps | 10.0 | 600 |
| 960x540 | 1.5 Mbps | 12.2 | 732 |
| 1280x720 | 3.2 Mbps | 25.0 | 1500 |
| 1280x720 | 4.5 Mbps | 34.7 | 2082 |
| 1920x1080 | 5.5 Mbps | 42.2 | 2532 |
This chart is for the storage needs of a single video presentation. Presentations that consist of multiple videos and smooth streaming will add to the storage needs. The technical explanation below shows how adding video streams and smooth streaming profiles adds to the storage needs.
If you have a dual video smooth streaming presentation with a 1280×720(3.2 Mbps) and 960×540(1.5 Mbps) profile the storage needs will be approximately 4,464 MB/hour
