How much recording time is 4gb
The reason why we do not usually state the recording capacity of the cameras in the reviews is because it depends on several factors. When both of these are known, you can calculate the maximum recording capacity using a simple formula.
Bear in mind that you can reduce the bit rate by lowering video resolution. So based on the size of the memory card and the bit rate, how can we calculate the total recording time? You are running your device at a p resolution for best video quality, resulting in a bit rate of approximately 15 Mbps. Divide this by 15 Mbits and the result is the number of seconds you can record. In other words, with a GB card the SGGCX2 can record continuoulsy for 1 day, 13 hours and 55 minutes before it will automatically start to overwrite the oldest footage.
If you just need a quick approximation of the total recording time in hours, of a dash cam or any other digital video camera, you can use this quick formula:. 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. Interested in more options? Here are the best microSD cards for GoPro cameras all models.
A 16GB memory card can hold approximately 9 videos. This is based on 4K resolution at 60fps — a standard GoPro video resolution. Average video time of 3 minutes. A 32GB memory card can hold approximately 19 videos.
A 64GB memory card can hold approximately 38 videos. A GB memory card can hold approximately 76 videos. A GB memory card can hold approximately videos. A 1TB memory card can hold approximately videos. Here are the maximum video bit rates when filming with GoPro cameras. Show only Search instead for. Do you mean. Search Results:. How many hours of video do I get with 4GB or more on a memory card? I'm going on a vacation for four days and I'm assuming I'll be recording around an hour each day.
How many GB's should I look for in a memory card? I thought there would be some easy to find standards on this, but I guess I have to consider fps and possibly other factors like the type of camcorder or memory card. Message 1 of 5 , Views.
