With the advent of 8K video and immersive media, file sizes are only going to increase. Video files are not all created equal — there are several factors that come into play when determining how big a video file will be.
Before you can start to compare videos you need to understand the various factors that contribute to large file sizes. In a standard p video there are roughly one million pixels that make up the picture. A 4K video on the other hand has eight million pixels.
The more pixels that make up the image, the higher quality it will be and the larger the file size.
The longer a video, the larger the resulting file size will be because the more data will be contained in the file. File formats like. The more a video is compressed, the lower quality and smaller file size it will be.
Many media professionals. The frame rate is subtle to the untrained eye, but this is what helps produce the smooth, cinematic feel you notice in Hollywood productions.
In video some standard frame rates include 24fps, 30fps and 60fps. The more frames you have in one second of video, the larger the file size will be. Using different frame rates or codecs? Try this handy calculator from Toolstud. Mp3s for example range in size from. The length of time it takes to move media is dependent on several factors:. How big is a video file? View Larger Image. What makes a movie file large? Many media professionals 4 Frame Rate The frame rate refers to the number of frames that make up one second of video.
What are the average movie file sizes? Mp3s for example range in size from How long does it take to move big files? Share with your friends and colleagues.In this part, we will tell you the details, or the logic, about how to calculate video file size.
Firstly, we need to know, or you may have known, that each video file consists of hundreds and thousands of images. And one image is called a frame in a video file, technically. So to answer the question, it seems that we need first to figure out how to calculate one frame image.
Each frame or image consists of many pixels. And how many pixels exactly it has depends on its horizontal pixels and vertical pixels, or the resolution. For example, one 4K image with x resolution, then its total pixels are I guess this is not hard to understand, right.
But the real question is how much storage one pixel takes up. If we know it, then the size of one frame equals that the size of one pixel times the resolution.
To figure out how much storage one pixel takes up, here is another knowledge point that we need to learn about. It is Bit Depth, or called Color Depth. Bit Depth means the color information stored in one pixel. Only when one pixel stores some colors, then the image can show us a cat, a dog, a flower, or something else.
The bigger the number of the bit depth, like 1-bit, 2-bit, 4-bit, 8-bit, bit, etc. The color of each pixel is the combination of the three primary colors: red, green, and blue. Each primary color is often called a color channel and can have any range of intensity values specified by its bit depth. The bit depth for each primary color is termed the bits per channel. The bits per pixel bpp refers to the sum of the bits in all three color channels and represents the total colors available at each pixel.
Here are some specific examples, which maybe help you understand those words above easily. This one is widely applied. Now we have pretty much get the Bit Depth clear. And in the following content related to Bit Depth, we will take the 8-bit per channel as an example to help us.
And at this time, we can also calculate how much storage one frame, or one image will take up. The formula, which we have mentioned above, is. Like we have said, we take the 4K resolution x and 8-bit per channel as examples.Any videos you record with your iPhone running iOS 11 will use the new H.
One of the goals of this new format is to create smaller files, but does HEVC live up to that claim? I figured it was good to use existing video shot for other purposes, to make the testing as objective as possible.
To generate the H. This gives you a. Here are the file sizes:. This generates a.
To visualize those size differences, look at the chart below. However, that video is zoomed in on fairly intricate objects, which may explain the inability of the iPhone to encode it at a higher compression ratio. The file sizes of HEVC files are consistently smaller, almost twice as small if not more than that.
Hopefully, the new standard will become more widely-supported in the near future. This site uses Akismet to reduce spam. Learn how your comment data is processed. It does. Flat color spaces, blurred, etc anything with minimal edge detail can be compressed quite a bit with little quality loss, though. For clarification, both the blue and green bars in the graph are labelled H.
I assume that the green bar is the H. I could have sworn those had different labels. Yes, green is H. Please Login to comment.Community Tech. Donut May 5, In real number what does that mean like pixels or more importantly how much storage is required per 1 minute 4K video?

Share this thread. Back to top.The technology will soon be within the reach of all video producers; even high-end hobbyists. Is 4K production cool? Is it sexy? But is 4K video production necessary? Does every producer need to race onto the 4K bandwagon? Maybe not. While everyone agrees that 4K video production is something all producers can celebrate and admire, and something to keep a close eye on as technology continues to improve, there are several things to consider before breaking the bank to buy into it just yet.
Every video producer knows that video eats up hard drive space. While 4K footage is beautiful, all those pixels, and all that additional data, take up a whole lot of space. The raw files are massive and the cost of hard drive space to meet the demands of an Ultra HD 4K video production can balloon very quickly.
Anyone planning to delve into the 4K arena needs to be prepared to incur more than just the cost of the camera, but also the ancillary cost of short-term and long-term storage. How much space might one need? Consider this: One hour of standard definition DV footage requires approximately The good news is that storage space does continue to get cheaper, however, the cost of storing massive 4K files is a very real factor that producers need to consider. In order to edit footage effectively, video editors need to be able to access and play back content without delay.
Big files move slowly and quickly bog down the creative process. Moving media around and playing back edits without waiting takes processor power and bandwidth that standard HD systems are not equipped to handle. For many video producers, editing 4K footage will require a major system upgrade. In addition to the need for increased hard drive storage capacity, editors may also be looking at costly upgrades for processor performance and software compatibility.
Because of the file sizes, many 4K editors edit using lower resolution proxy filesbut even this stacks on additional post-production time. The time needed to work with 4K video in post is something that anyone who needs to work fast, may not have the time to deal with. For many producers, edits take long enough already. Before adding the hard cost of system upgrades and the soft costs associated with extended post-production time, editors need to give serious consideration to whether their return on investment will be justifiable.
While 4K video production is something all producers can celebrate, there are several things to consider before breaking the bank to buy into it just yet. For years, low resolution formats have covered a lot of cinematic sins. As cameras capture images in greater resolution, producers need to become increasingly attentive to even the smallest details. They say that the devil is in the details, and when it comes to 4K content, there is no place for imperfections to hide.
While 4K may be fantastic for shooting scenic shots, it can be a particularly unforgiving format for shooting people.
Just imagine the hyper-clarity of every freckle, wrinkle and tuft of ear hair.How to Calculate the File Size of a Video
Anything unintentionally soft will be glaringly soft. Shooting 4K will require producers to operate with an increased attention to detail. In order for viewers to appreciate 4K movies, they need to have 4K playback and display hardware in their home.Planning your feature film production is essential. Depending on your shooting ratio, the length of the material to be shot, the number of cameras you use, the format you choose to shoot in, the hard-drive space you will need will vary.
Scenario 1 — Shooting in p with two Canon 7Ds:. If you decide to shoot in p This is roughly 42GB in p. Ok, so far so good, but what will happen if you decide to transcode into ProRes? So, if you want to keep your original H.
If you shoot with one camera than that equals 5,67TB of hard disk space total for the entire project. There is no need for transcoding. Furthermore, with the newest 1. Shooting in 4K is a whole new thing. You would need to expand your storage definitely if you are shooting at such high data rates. This is an interesting case.
Then, 25 hours 1 hour per day equals around 1 TB. This is a really great and efficient option and definitely will be my personal choice. Choosing the most convenient codec for your project is a mandatory prerequisite for the creative process. Get Instant Access!
