Determine how many minutes of video you can record on a memory card with your Canon 5D Mark IV at different resolutions and frame rates. This calculator helps you plan your shoots by estimating recording times based on your card's capacity.
How to Use This Calculator
To calculate your memory card's video capacity for your Canon 5D Mark IV:
- Enter your memory card's capacity in gigabytes (GB)
- Select the video resolution you plan to shoot
- Choose the frame rate you'll be using
- Click "Calculate" to see how many minutes of video you can record
The calculator will display the estimated recording time and show a chart comparing different resolutions at your selected frame rate.
Formula Used
The calculation is based on the following formula:
Where:
- Card Capacity is in gigabytes (GB)
- Resolution Bitrate is in megabits per second (Mbps)
- Frame Rate is in frames per second (fps)
Note: These are approximate values. Actual recording times may vary slightly due to file system overhead and other factors.
Worked Example
Let's calculate how many minutes of 4K video at 30fps you can record on a 128GB card:
So with a 128GB card, you can record approximately 12 minutes of 4K video at 30fps.
Resolution Comparison
Here's a comparison of recording times for different resolutions at 30fps on a 128GB card:
| Resolution | Bitrate (Mbps) | Recording Time |
|---|---|---|
| 4K (3840×2160) | 360 | 12 minutes |
| Full HD (1920×1080) | 120 | 87 minutes |
| HD (1280×720) | 60 | 174 minutes |
| 720p (1280×720) | 40 | 262 minutes |
FAQ
What memory card formats does the 5D Mark IV support?
The 5D Mark IV supports UHS-II SD cards (U3 speed class) and CFexpress Type B cards. For best performance, use UHS-II SD cards with high endurance ratings.
How does compression affect recording time?
The calculator uses standard bitrates for uncompressed video. Actual recording times may vary slightly depending on the compression settings you use in-camera.
Can I use dual card slots for longer recording?
Yes, the 5D Mark IV supports dual card slots, allowing you to record to two cards simultaneously. This effectively doubles your recording time.
