Does SD Card Make Video Quality?

When it comes to capturing videos, there are a lot of factors that come into play to determine the overall quality of the video. One of those factors is the type and quality of the SD Card used in capturing the video. In this article, we will explore whether or not an SD card has an impact on video quality.

What is an SD Card?

An SD (Secure Digital) card is a small storage device that is commonly used in many different types of electronic devices, including cameras and smartphones. It allows you to store data, such as photos and videos, on a small chip that can easily be removed from your device.

Does an SD Card Affect Video Quality?

The short answer is yes, the type and quality of your SD card can have an effect on the overall quality of your video. This is because when you record a video, your camera needs to write a large amount of data onto the SD card very quickly. If your SD card can’t keep up with this data transfer rate, then your camera may not be able to record high-quality video.

Types of SD Cards

There are several types of SD cards available in the market but two major ones are:

  • Standard SD Cards
  • SDHC/SDXC Cards

Standard SD cards typically have storage capacities up to 2GB. They are suitable for lower resolution videos such as 480p or 720p videos. However, if you want to shoot high-quality videos such as 1080p or 4K resolution videos then you will need an HD (High Definition) capable memory card.

HD-capable memory cards include both Secure Digital High Capacity (SDHC) and Secure Digital Extended Capacity (SDXC) cards. They offer faster data transfer rates which makes them better suited for high-resolution video capture.

Speed Class Ratings

SD cards come with different speed class ratings that indicate their minimum write speeds. These speed ratings include:

  • Class 2 (minimum write speed of 2MB/s)
  • Class 4 (minimum write speed of 4MB/s)
  • Class 6 (minimum write speed of 6MB/s)
  • Class 10 (minimum write speed of 10MB/s)

If you plan on shooting high-quality videos, then it’s recommended that you use an SD card with a Class rating of at least Class 10. This will ensure that your camera can write data quickly enough to capture high-quality video without any lag or buffering issues.


In conclusion, the type and quality of your SD card can have an impact on the overall quality of your video. If you plan on shooting high-resolution videos, then it’s important to use an HD-capable memory card with a fast enough write speed to keep up with the demands of your camera. By using the right SD card, you can ensure that your videos are captured at the highest possible quality.
