How to Calculate the Ideal SD Card Size for Your Video Camera
Calculating the ideal SD card size for your video camera can be a bit tricky, but here’s a simple formula to help you get started:
- Determine the resolution and frame rate of your video footage.
- Calculate the bitrate of your video footage using an online bitrate calculator.
- Determine the length of your recording sessions.
- Multiply the bitrate by the length of your recording sessions to get the total storage space required.
- Add a 10-20% buffer to the total storage space to account for any unexpected storage needs.
For example, let’s say you’re shooting 4K video at 30fps with a bitrate of 100Mbps. You’re planning to record for 2 hours, and you want to add a 10% buffer to the total storage space.
Using the formula above, you would calculate the total storage space as follows:
100Mbps x 2 hours = 12GB
12GB x 1.1 (10% buffer) = 13.2GB
In this case, you would need an SD card with a minimum size of 16GB to store all the footage.
