It’s important to note that the actual usable storage capacity of an SD card may be slightly less than its advertised capacity. This is because the card’s file system and other overhead can consume a small portion of the total capacity. However, these differences are usually minimal and do not significantly impact the available storage space.
In summary, a 64GB SD card is a portable storage device with a capacity of 64 gigabytes. It is commonly used in electronic devices to expand their storage capabilities, allowing users to store and transfer large amounts of digital data.
Video File Sizes
Understanding video file sizes is crucial to determining how much footage you can store on a 64GB SD card. Video file sizes can vary depending on various factors, including the video format, resolution, frame rate, and compression settings.
Video files are usually measured in terms of file size per unit of time, such as megabytes per second (Mbps) or gigabytes per hour (GB/h). The higher the file size, the more storage space it occupies.
The most common video formats include MP4, AVI, MOV, and MKV. Each format has its own compression algorithm and quality settings, resulting in different file sizes for the same video content.
Video resolution also plays a significant role in file size. Higher resolutions, such as 4K or 1080p, produce more detailed and visually appealing videos but also result in larger file sizes. Lower resolutions, such as 720p or standard definition, have smaller file sizes but may lack the same level of clarity and sharpness.
Another factor that affects video file sizes is the frame rate. The frame rate determines the number of frames displayed per second in a video. Common frame rates include 24 fps (frames per second), 30 fps, and 60 fps. Higher frame rates result in smoother motion but also lead to larger file sizes.
Compression settings also have a significant impact on video file sizes. Compression algorithms, such as H.264 or H.265, reduce the file size by eliminating redundant information while maintaining acceptable video quality. Higher compression ratios result in smaller file sizes but may also result in a slight loss of quality.
It’s important to consider these factors when choosing the video format, resolution, frame rate, and compression settings for your recordings. Finding the right balance between video quality and storage space will ensure that you make the most efficient use of your 64GB SD card.

Recording Time Calculation Formula
To estimate the recording time on a 64GB SD card, you can use a simple calculation formula that takes into account the video file size and the storage capacity of the SD card.
The formula is as follows:
Recording Time (in hours) = Available Storage Space (in GB) / Video File Size per Hour (in GB/h)
To begin, you need to determine the average video file size per hour. This will vary depending on the video format, resolution, frame rate, compression settings, and other factors discussed earlier. By referring to the manufacturer’s specifications or conducting some test recordings, you can estimate the file size per hour of video footage.
Next, you divide the available storage space of your 64GB SD card by the file size per hour. The result will give you an estimation of the recording time in hours that can be accommodated on the SD card.
For example, if the average video file size per hour is 4GB and you have a 64GB SD card, the calculation would be as follows:
Recording Time (in hours) = 64GB / 4GB/h = 16 hours
Keep in mind that this calculation provides an approximate recording time and may not account for other factors such as formatting overhead or file system limitations. Additionally, the actual usable storage space on the SD card may be slightly less than the advertised capacity.
By using this formula, you can get a general idea of how many hours of video footage you can expect to store on a 64GB SD card. This can help you plan your recording sessions and ensure that you have enough storage space to capture all the important moments.
How Many Hours of Video Can a 64GB SD Card Hold?
A 64GB SD card can hold a varying number of hours of video, depending on factors such as the video format, resolution, frame rate, compression settings, and bitrate. While the exact number may differ based on these variables, we can make some general estimations based on average file sizes and recording settings.
Let’s assume that the average video file size per hour is approximately 4GB, which is a reasonable estimate for high-quality video footage. By using the recording time calculation formula discussed earlier:
Recording Time (in hours) = Available Storage Space (64GB) / Video File Size per Hour (4GB/h)
Using this formula, we can determine that a 64GB SD card can hold approximately 16 hours of video footage. However, it’s important to note that this is just an approximation and the actual recording time may vary based on the aforementioned factors.
If you are recording in lower resolutions, using lower bitrates, or employing more efficient video codecs, you may be able to fit more hours of video on the SD card. On the other hand, higher resolutions, frame rates, and bitrates will result in larger file sizes and subsequently fewer hours of video storage.
For example, if you are recording at 1080p resolution with a higher bitrate, the average file size per hour may increase to 8GB. In this scenario:
Recording Time (in hours) = 64GB / 8GB/h = 8 hours
It’s important to consider your intended video quality and recording settings when estimating how many hours of footage you can fit on a 64GB SD card. Adjusting the recording settings to strike a balance between video quality and storage space can help you make the most efficient use of your SD card’s capacity.
