Understanding Sony Video Data Rates
When shooting with Sony Alpha or Cinema Line cameras (such as the a7S III, FX3, FX6, or a7 IV), understanding data rates is crucial for media management. Sony utilizes various iterations of the XAVC codec, including XAVC S (Long GOP), XAVC HS (H.265), and XAVC S-I (All-Intra), each with drastically different storage requirements.
Mbps vs. MB/s: The Critical Distinction
Camera settings are displayed in Megabits per second (Mbps), while storage cards and hard drives are measured in Megabytes (MB) or Gigabytes (GB). The conversion factor is 8.
- 100 Mbps (common for 4K 24p) = 12.5 MB/s.
- 600 Mbps (XAVC S-I 4K 60p) = 75 MB/s.
This calculator automatically handles this conversion to tell you exactly how many Gigabytes (GB) you need for your shoot, or how long your CFexpress Type A or SD card will last.
Codecs and Media Requirements
XAVC S-I (All-Intra): This codec captures every frame individually without compression between frames. It requires the highest data rates (often up to 600 Mbps for 4K 60p) and typically requires V90 SD cards or CFexpress Type A cards.
XAVC S / XAVC HS (Long GOP): These compress data across groups of frames. They are more efficient, saving space (often 100-200 Mbps), but require more processing power from your computer during editing.
How to Use This Calculator
- Select Preset: Choose a common Sony recording setting from the dropdown, or enter a custom bitrate in Mbps found in your camera menu.
- Card Size: Enter the capacity of your media card (e.g., 80GB, 160GB, or 64GB).
- Duration: Enter how long you plan to record (in minutes).
- Calculate: The tool will output the total file size required and the maximum recording time your card can support.
