And how many videos each memory card size can hold. And how many hours of video can 64GB hold? For many years, the standard video resolution of GoPro cameras is 4K.
I like this resolution because it captures so much detail. And it allows lots of flexibility in editing. How many videos per GB? 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.
Because of the file sizes, many 4K editors edit using lower resolution proxy files , but 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. 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.
As of early , there is almost nothing on the market that allows consumers to catalog, play and view 4K content. While there are now some Blu-ray players that upscale Blu-ray content for improved resolution on a 4K television, they do not play true 4K content. Because there are limited mediums for distributing 4K to the home, a limited catalog of 4K movies for people to buy and bring home, and virtually no consumer device for playing 4K content, most people will not be able to fully appreciate footage produced in 4K.
They simply cannot view it. Digital content distributors like Netflix and Hulu may soon be pushing 4K movies and TV shows to the home, and as Internet bandwidth continues to improve, online media distribution hubs like Vimeo may one day allow content creators to post and share 4K content online, but in the short term, the bandwidth to stream 4K content is not adequate.
Right now, the only practical way an independent producer can deliver 4K content to a client is on a hard drive. From a practical point of view, until a means of 4K content delivery is installed in the living room, 4K will function primarily as an acquisition format. Home theater experts say that the viewability of ultra-high resolution footage depends entirely on screen size and viewing distance. Sony backs up this data in an Amazon.
Buying a 4K camera and switching to a 4K workflow will not in and of itself make your work better, and it will certainly not make you a more effective or successful producer.
For many people, newer and better technology can become a blockade to creativity. This argument is certainly not specific to 4K video production, but there is truth to this notion that better tools do not equal better work, and we must always take that fact into consideration as we are confronted with each new technological breakthrough that, either overtly or covertly, promises to miraculously make our work more professional.
Making great media is about far more than increased resolution and clarity. Even in the age of 4K, content will still reign as king.
Masterful use of lighting, composition and edit sequencing will always trump pure, straight resolution. Merely owning better tools does not magically make anyone a better visual communicator.
