Does UHS 1 Support 4K? A Beginner's Guide
4K video is becoming increasingly popular, but it can be a bit daunting to figure out what kind of memory card you need to record and store it. One of the most common questions is whether or not UHS 1 supports 4K video.
The answer is: yes, but it depends.
UHS 1 is a bus interface that allows SD memory cards to transfer data at faster speeds. It has a maximum theoretical transfer speed of 104MB/s, but most UHS 1 cards in real-world use will transfer data at speeds closer to 60-80MB/s.
4K video, on the other hand, requires a minimum sustained write speed of 30MB/s. This means that any UHS 1 card with a V30 or higher video speed class rating should be able to support 4K video recording.
However, there are a few things to keep in mind:
- Not all cameras support UHS 1. Be sure to check your camera's manual to make sure that it supports UHS 1 cards before you buy one.
- Not all UHS 1 cards are created equal. Some UHS 1 cards may have a V30 video speed class rating, but they may not be able to maintain that speed consistently. It's important to choose a UHS 1 card from a reputable manufacturer and to read reviews before you buy.
- The bitrate of your video will also affect whether or not your UHS 1 card can support it. A higher bitrate will require a faster write speed. If you're planning on recording 4K video at a high bitrate, you may need to use a UHS 2 card instead.
Here are some tips for choosing a UHS 1 card for 4K video recording:
- Look for a card with a V30 or higher video speed class rating. This will ensure that the card has the minimum sustained write speed required for 4K video recording.
- Choose a card from a reputable manufacturer. Some manufacturers are known for making high-quality memory cards that can maintain their rated speeds consistently.
- Read reviews before you buy. This is a good way to get feedback from other users and to see how well the card performs in real-world use.
If you're not sure whether or not your UHS 1 card can support 4K video recording, it's always best to err on the side of caution and use a UHS 2 card instead. UHS 2 cards are faster and more reliable, and they will give you more peace of mind when recording 4K video.
Here are some additional things to keep in mind when recording 4K video:
- Use a fast SD card reader. A fast SD card reader will help you to transfer your 4K video files to your computer more quickly.
- Make sure your computer is powerful enough to edit 4K video. 4K video editing can be quite demanding, so you'll need a computer with a powerful CPU and GPU.
- Back up your 4K video files. 4K video files are very large, so it's important to back them up regularly to prevent data loss.
Conclusion
UHS 1 cards can support 4K video recording, but it depends on the camera, the card, and the bitrate of the video. If you're not sure whether or not your UHS 1 card can support 4K video recording, it's always best to err on the side of caution and use a UHS 2 card instead.
