Photography Memory Card Speed & Capacity Selector for 4K Video

Select the right memory card speed class, capacity, and type for 4K video recording based on camera, bit rate, and shoot length to avoid buffer errors and lost footage.

‍

Essential for videographers shooting high-res or long clips.

‍

We ask for camera type, video resolution/bit rate, shoot length, speed class needed, capacity preference, current issue, and budget level because these prevent buffer errors (e.g., V90 for 4K 120fps). These inputs ensure reliable recording. Limitation: the tool uses manufacturer bit rate estimates; real performance depends on card brand and camera firmware.

Memory Card Selection for Action Cam / GoPro

Recommended Specifications

1. Speed Class: V60
   • Explanation: A Video Speed Class of V60 ensures a minimum write speed of 60MB/s, which is essential for recording high-quality 4K video at 60fps. This class is ideal for medium bit rate recordings, providing a buffer against dropped frames.

2 Capacity: 256GB

• Explanation: A 256GB card strikes a balance between ample storage for high-resolution footage and portability. This size helps prevent the card from filling up too quickly, allowing for extended shooting sessions without the need to frequently change cards.

3. Type: UHS-I or UHS-II
   • Explanation: Choose UHS-I for most action cameras, as they are typically optimized for this standard. UHS-II cards can provide faster transfer speeds but may not be fully utilized by all action cameras. Ensure compatibility with your device.

Understanding UHS/V Ratings

• UHS (Ultra High Speed): Cards are rated as UHS-I or UHS-II, indicating their potential speed. UHS-I cards can reach speeds up to 104MB/s, while UHS-II cards can achieve much higher speeds (up to 312MB/s). However, most action cameras will operate effectively with UHS-I.
• V Ratings: These ratings (V6, V10, V30, V60, V90) represent the minimum write speeds. For your needs:
  • V60: Minimum write speed of 60MB/s, suitable for 4K 60fps video.

Bit Rate Requirements

• Medium Bit Rate: Generally falls around 50-100 Mbps for 4K 60fps video. To ensure smooth recording, the card should comfortably handle this bit rate, which is well-supported by the V60 rating.

Tips for Optimal Usage

1. Regular Formatting: Regularly format your card in the camera to prevent file system errors and ensure optimal performance.
2. Avoid Overheating: Ensure your camera has good ventilation to prevent overheating during long recording sessions. Overheating can lead to dropped frames.
3. Data Backup: Regularly back up your footage to avoid data loss. Consider multiple cards for longer shoots.
4. Check Compatibility: Always verify that your action camera supports the card type and speed class you are considering.
5. Buy from Reputable Brands: Stick to trusted brands with good warranties, such as SanDisk, Lexar, or Samsung, to ensure reliability and performance.
