Introduction
With the evolution of imaging technologies, 4K and 8K recordings have become accessible to a wide audience. Whether for a vlog, a short film, a documentary or professional videos , choosing the right SD memory card is essential to ensure smooth recording without loss of quality .
A slow memory card can cause stuttering, interruptions, and even file loss during recording. Therefore, it's crucial to choose a fast, reliable card with enough capacity to store large video files.
In this article, we'll look at which SD card to choose for shooting 4K and 8K , based on write speed, capacity, and video certifications .
Why is a fast SD card essential for 4K and 8K video?
When a camera records 4K or 8K video, it generates an extremely large data stream . A slow SD card will not be able to keep up with the write rate , resulting in recording interruptions or corrupted files .
Problems with an SD card that is not suitable for high-definition video include:
A jerk in the recording that affects the fluidity of the images and the final rendering of the video.
An abrupt stop to filming because the card cannot process the data quickly enough.
Corruption of files preventing them from being read or used in post-production.
Too long a transfer time to retrieve the files and process them on the computer.
To avoid these inconveniences, it is crucial to choose an SD card optimized for 4K and 8K video , which guarantees stable and smooth flow.
What speeds are required for 4K and 8K video?
SD cards are rated by their minimum write speed , which is essential for high-definition video capture. Here are the standards you need to know:
U1 cards (10 MB/s minimum) are suitable for Full HD (1080p) videos, but too slow for 4K.
U3 / V30 cards (30 MB/s minimum) are suitable for standard 4K videos at 30 or 60 frames per second .
V60 cards (60 MB/s minimum) allow smooth recording in 4K at high speed and the start of capture in compressed 8K .
V90 cards (90 MB/s minimum) are essential for uncompressed 8K videos or professional RAW shooting.
A V30 card is a minimum recommended for 4K , while a V60 or V90 is required for lossless 8K recording .
What SD card capacity should I choose for 4K and 8K video?
The choice of capacity depends on the size of the video files and the desired recording duration.
A 128GB card can shoot about 1 hour of 4K video at 60 FPS , which is enough for short projects.
A 256GB card is ideal for more frequent use and allows you to record up to 2 hours of 4K video .
A 512GB card is recommended for videographers shooting long 4K content or short 8K clips .
A 1TB or 2TB card is essential for 8K video professionals or those who want to store several hours of footage without interruption .
Choosing a high-capacity SD card helps avoid shooting interruptions and frequent card changes , which is essential for long-term projects.

Avoid removing the SD card abruptly while writing a file to avoid the risk of corrupting the data.
