Jun 16, 2020 · There is a range of acceptable bitrates for each standard video resolution. Most mid-range cameras that can record 4K videos have bitrates between 85 to 95 megabits per second. This corresponds to about 11.5 MB per second or 690 MB per minute. This is a very rough approach to calculating the video file size. However, it will do if you just need ...
Jul 27, 2024 · To calculate this result, follow these steps: Calculate the frame size by multiplying the vertical resolution, horizontal resolution, and color depth: frame size = 1920 × 1080 × (3×8) = 49,766,400 bits = 6,220,800 bytes or 6.2208 MB. Multiply frame size by the video's frame rate and runtime in seconds to get the video file size: file size ...
Jan 14, 2020 · Step 1: Load your oversized 4K video. Launch the 4K video converter and click “+Video” button to import the 4K video (s) to the program. By the way, save 4K videos locally on computer from your SD card or mobile in advance. Step 2: Compress 4K video based on your requests.
- Pick the Right Software. You really should use a computer for this task, not a tablet or a smartphone (though you can compress a video on iPhone). The best desktop tool for this task is Handbrake.
- Start With the Audio. Before you begin chopping down the quality of the picture itself, take a peek at the Audio tab in Handbrake. You might be surprised by how much space audio channels take up; unless your project requires extremely high-quality audio above all else, always tackle sound first.
- Choose the Best Codec and Container. Ideally, the original video you shoot should be using the highest quality video codec and container. When you're ready to reduce the size, you pick the most efficient codec and container.
- Reduce the Video Resolution. Most people have HD-ready or full-HD TVs, but the big secret is that video resolution isn't as important as you might think.
1 kilobyte = 1024 bytes; 1 byte = 8 bits; So 70778880 bits = 70778880/ (8 x 1024 x 1024) MB = 8.4375 MB. That is to say, for 4K video file with 8-bit Bit Depth, the size of one frame is 8.4375 MB. Now we can answer the question of how to calculate video file size, and here is the video file size formula,
Nov 9, 2023 · But all those extra pixels come at a cost – much larger file sizes! A 4K video will require significantly more storage space compared to HD video of the same length. Just how much more? Let‘s crunch some numbers… Estimated 4K Movie File Sizes. The bitrate (amount of data used per second) largely determines the size of a video file.

Jun 25, 2014 · You would need to expand your storage definitely if you are shooting at such high data rates. A single hour of 4K footage is a whopping 318 GB. 25 hours of 4K ProRes equals roughly 7.76 TB. 7.76TB (the ProRes UHD files from a single BMPC 4K camera) x 3 ( for the back up) = 23.28 TB of hard disk space in total required.
