You can fit between 1. Or videos with an average length of 45 seconds, depending on resolution. This is based on a video resolution of 2. For more detail, check out this chart showing the effect of video resolution on storage capacity. While these will be true for other cameras and models, the calculations in this chart are based on my Hero8 Black.
For my methodology, see my explanation below the chart. To ensure that it was empty, I reformatted it. Then I set the video resolution and frame rate to each of the settings above. The available space noted by time remaining on the SD card is noted in the top left of the LCD screen.
I then divided the time remaining by 64 the number of GB on my card to determine the number of minutes per GB of storage space. Please note that the video size is approximate. As noted in the next section, there are lots of factors affecting the size of a specific video file. The purpose of this post is to give an overview and an approximate base. Of course, if you replicate my settings exactly, your file size and card capacity will also match.
There are a number of factors that will affect the size of each video. They include video bitrate, frame rate, video length, video container, and other files stored on the same card. Does video resolution affect file size? You might think that this would be a significant factor when comparing memory card capacity. But file size actually depends more on frame rate and bitrate. For example, in my tests, both p fps and 4K 60fps both generated an identical file size MB.
The bitrate for both was 60 Mbps. Video length was 60 seconds. To help you plan card usage, here is a chart that breaks down the video capacity of each memory card size. Left column: First number is video resolution 4K, 2,7K, etc. Second number is aspect ratio , Third set of numbers shows frame rate 24, 30, etc.
Here is the detailed breakdown for of the video capacity in hours. This chart is the same data, except with data converted to hours. They come in sizes from 32GB to 1TB. YouTube suggests encoding at a minimum bit rate of 1, kbps for its lowest-resolution format. For a full high-definition video it recommends a minimum bitrate of 8, kbps plus kbps for stereo audio. This would translate to around 4 hours and 17 minutes on a 16GB card. SanDisk suggests a 16GB card could hold 10, photos taken at a 5-megapixel resolution.
This is a common resolution on smartphone cameras and mid-range digital cameras. More expensive camera phones have a higher resolution. For example, the Galaxy S3, which supports SD cards, has an 8-megapixel camera, which would reduce the capacity to 6, photos.
