Do SD Cards Affect Video Quality?

Many people wonder if the type of SD card they use can affect the quality of their video recordings. The answer is yes, it definitely can.

Why Does the Type of SD Card Matter

The type of SD card you use in your camera or other recording device can impact the quality of your videos in several ways. For example:

  • The write speed of the card can impact how quickly your device can record video and how smoothly it will play back.
  • The storage capacity of the card can impact how much footage you can capture before needing to transfer files or switch to a new card.
  • The class rating of the card is an indication of its minimum write speed and determines whether or not it’s suitable for recording high-definition video.

What Are the Different Types of SD Cards

There are several different types and classes of SD cards available on the market, each with its own set of specifications that determine its performance capabilities. Some common types include:

  • SDSC (SD Standard Capacity)
  • SDHC (SD High Capacity)
  • SDXC (SD Extended Capacity)

Class Ratings

In addition to capacity, another important factor to consider when choosing an SD card for video recording is its class rating. The class rating indicates the minimum write speed required for a particular use case, with Class 2 being suitable for standard definition video recording and Class 10 being suitable for high-definition video recording.

If you’re planning to record high-quality footage at a high frame rate or bit rate, you’ll want to choose an SD card with a higher class rating to ensure that it can keep up with the demands of your recording device.


While it may be tempting to go for a cheaper or lower-class SD card when recording video, doing so can result in poor quality footage and frustration. By investing in a high-quality SD card that’s appropriate for your device and use case, you’ll be able to capture smooth, clear video footage without any hiccups or interruptions.
