Computers may have changed the way video is edited, but few spend time considering what components are being used inside their wonderful machines or whether different configurations would make for a better, more efficient workflow. With 4K video fast becoming a standard, a desktop workstation must meet certain requirements in order to be able to edit video without difficulties. The components making up the workstation must be attuned to the type of video being edited and to the software being used. This will enable you to edit in an efficient and creative manner that not only gets the work done, but gets it done on time and in a way that meets your creative needs. Let’s separate out each of these computer components to best understand what is needed.


The central processing unit (CPU) can basically be thought of as the computer’s brain, one that does nothing but process numbers. Since numbers are what programs are made of, that’s pretty important. The speed at which a CPU crunches those numbers translates into how programs are executed and how the computer performs overall. To get a picture of how well a particular CPU behaves, one can look for how fast it is, which is dictated by its clock speed, usually expressed in gigahertz (GHz), as well as how many cores it has, its instruction set, memory bandwidth, cache and other factors.

One of the roadblocks that a CPU once had is the fact that it had to handle everything that the computer was being asked to do, and that especially was problematic when it came to processing graphic-intensive tasks. This led to the development of the GPU chip (Graphics Processing Unit), which is meant to take some of the weight off of the CPU by devoting itself to handling graphic processing tasks.

While a CPU can perform similar functions as that of the GPU, the fact that the GPU is specialized means that it can perform its functions faster and better. It also helps that, unlike a CPU, the GPU isn’t composed of just a few cores handling a few software threads at a time; GPUs are able to process thousands of threads all at the same time due to being composed of hundreds of cores. Working in tandem with the CPU, GPU-accelerated computing provides for increased overall performance and is supported by the latest operating systems.


While similar in appearance, RAM and VRAM perform different functions. RAM (Random Access Memory) can be found in slots on the computer’s motherboard, most often accessible and replaceable– except in cases where it is soldered on. Its purpose is to load in the operating system as well as to load programs into its memory in order to run them. Higher amounts of RAM will enable a computer to run faster than one with less memory since more data can be accessed without having to load it in from your hard drive or other storage device. As a result of faster and more intensive operating systems, the typical computer will have a minimum of 4 or 8GB of RAM, though meeting the demands of certain intensive programs often requires adding to that number.

VRAM, or Video RAM, focuses on storing graphic data and so works with the GPU. The amount of VRAM dictates how many 2D and 3D images can be displayed at a time, with the complexity of the images and frame rate also being a factor. When VRAM reaches its limit, it offloads to system RAM, which negatively impacts performance. It is for this reason that a video card will often have 4GB or more dedicated only to VRAM.

CUDA vs. OpenCL

Before getting to CUDA and OpenCL, we must address GPGPU, or general purpose computing on graphics processing units. This allows the GPU, which typically handles a computer’s graphics needs, to aid the CPU in processing data. Without GPGPU, data would go from the CPU to the GPU, but the GPU could not transfer any data back to the CPU. GPGPU allows for data to be transferred bidirectionally between the CPU and the GPU. This improves the efficiency of the computer’s functionality as related to images and video.

OpenCL (Open Computing Language) is a framework for writing programs which executes across heterogeneous platforms consisting of CPUs, GPUs and other processors or hardware accelerators. It is maintained by a non-profit consortium that includes Intel, AMD, NVIDIA, Apple and others among its members. An example of a software program that supports OpenCL is Final Cut Pro X on a Mac.

Unlike OpenCL, CUDA is a proprietary parallel computing platform and programming model created by NVIDIA to make using a GPU for general purpose computing simple and efficient. An example of a software program that supports CUDA is Adobe Photoshop CC.

Both CUDA and OpenCL work to allow GPGPU to accelerate processing in an application, as long as the application supports at least one of these two platforms, working to take advantage of hardware that supports the relevant GPGPU framework.


Storage options come in two basic configurations: hard disk drives (HDDs), which use a physical spinning disc that has data written to and read from it, and solid state drives (SSDs), which use memory chips to contain the data. An HDD operates at one of two speeds, 5200 revolutions per minute or 7200 revolutions per minute. This speed determines the quickness at which the drive can read and write data.

Having no moving parts, it’s obvious that the life-cycle of a solid state drive will be longer than that of a spinning disk drive, but at this time, solid state drives are much more expensive to purchase than hard disk drives, especially when reaching terabytes of storage capacity. For this reason, hard drives continue to be the drive of choice for containing content for video editing, while solid state drives are popular as boot drives.


There are a number of connectivity systems in play today. The most common ones are USB 2.0 — now the oldest and slowest at 480Mbps — USB 3.0.0  at 5Gbps, Thunderbolt 2 at 20Gbps and Thunderbolt 3 USB Type-C, the newer standard now catching hold capable of transferring data at up to 40 Gbps. As can be seen, there are significant differences in the speed as to how each of these transfer data, which affects the ability of the user to work in an efficient manner.

Upgradability and Expansion Capabilities

One of the reasons PC computer sales overshadow those of Macintosh computers is due to the expandability of the chassis. Any PC can be upgraded and expanded — for example the video card it came with can be replaced with a faster or more graphic-intensive model, the amount of memory increased, or the number and types of hard drives added internally. In addition, core technologies like the CPU can be upgraded or replaced entirely. It is possible to construct a PC wholly oneself; this allows for making a customized model that fits one’s needs more specifically than could be possible by buying an off-the-shelf model. This is not true with most Apple computers.

The Final Component Is You

A desktop workstation can enable the video editor to attain their vision without restrictions or time-wasting stoppages. That said, it’s up to the person staring at the monitor to make sure that the workstation being used is the best one possible for their needs.

SIDEBAR: What To Purchase Within Your Machine and What To Upgrade Later

The abilities of a desktop workstation should exceed the type of work that it is being called upon to do. If the type of video that will be worked on will be Full HD (1080p) but no greater, then having hardware with 4K video capability is not required. Continuing with the 1080p example, hard drive space does not need to be as intense, nor does there need to be as much RAM memory (nor the speed at which the video can be processed as fast). This can then be addressed at a later time, should the type of video being worked with changes, by going to a faster CPU, a more graphic intensive video card (both of which can be installed by the user in most cases or through an authorized dealer). Unfortunately this is less true for Mac users, in the case of iMacs, but does exist for the older Mac Pro towers as well as the more recent

PC users don’t have any restrictions in this matter, since it is possible to custom build a desktop workstation from scratch.

  1. Do your think that I can use this device like travel tool for light video editing..?
    16gb ram
    INTEL IRIS PLUS graphics 640

  2. Hi Neby,

    No reason why you couldn’t use this hardware for light video editing at 4K.

    The only limitation may be the graphics card; if the laptop you have is the same as this one (except for the CPU, RAM and SSD capacity differences):
    the 2k resolution may not be adequate for seeing any rendering issues with 4k footage, that may reveal themselves when playing back the edited video on a 4k video player or a computer with a 4k graphics card, onto a 4k screen.

    The only other drawback will be during color grading. I have an HP laptop and I edit 2k video on its 15″ screen. I discovered that for color grading, it’s best to connect the laptop to a larger screen, such as a 32″ screen. I was very dismayed with the color errors revealed by playing the video back on a much larger screen, that never showed up on my laptop’s 15″ screen.

    The system’s performance may be dependent on the video file codec to be worked on. Uncompressed file formats, for example RAW, may require further processing time.

    Make sure when editing on your laptop, to have the Windows System configuration set for optimal performance, at the cost of battery charge duration.

    The CPU on your laptop has sufficient number crunching power for professional grade video editing.

    I’d also recommend backing up all the raw (not necessarily referring to RAW codec, but to unedited footage directly taken from the camera’s mass storage medium/media) videos and edited works, onto an external 2.5″ Hard Disk Drive. I exclusively use Seagate brand because in my experience I find Seagate most reliable; I’ve had many sad stories of data losses from IBM, Western Digital and Maxtor.

    The rendering time needs to be carefully planned into the work flow, as this may be the longest task the computer is required to do during post.

    There is also no reason why you couldn’t have a second computer system with a 4k capable graphics card a dedicated 4k monitor (TVs tend to include color correction firmware that may seriously detriment the look of the footage displayed on different brands of TVs due to variations in color calibrations) or a TV that has a menu option to disable automatic color correction, to handle the 4k color grading and other picture adjustment jobs, to finalize the video editing of your project, and make the footage look as close to the vision you have in mind, within the limitations of the available technology and your wallet (I do my video editing on a shoestring budget, and I can’t afford even a 2k monitor without automatic color correction, so I spend far too much time tweaking the color correction settings to get the look I want on two different TVs).

    One big advantage of editing on a laptop, is if there’s an interruption to the mains power supply, the laptop’s battery automatically provides backup power, to let a person work until the power is restored or at least to allow for work to be saved when the battery starts to run low, and the power company hasn’t restored the mains power in time. Another advantage offered by a laptop, is that video editing can be done on the road.

    One big advantage of editing on a desktop, is that it’s possible to upgrade the video card as GPU and VRAM technology evolves. With some desktop motherboards it may be possible to upgrade the CPU for a faster number cruncher. Although when it comes to CPU speed, raw clock speed is not always a good guide to determine the best CPU for a particular task. For example, the two major CPU companies are Intel and AMD; Intel has dominated the CPU benchmark performance stakes, when different technical web sites run performance tests, even when comparing faster clocked AMD CPUs with slower clocked Intel CPUs. Why? The answer is because Intel developed a superior CPU register architecture, which allows for faster software execution, through more efficient routing of data between their CPUs’ internal registers, and more efficient CPU instructions and data allocation between CPU cores. This is why Intel’s i7 line has remained the pinnacle of CPU performance, even though AMD has been pushing their CPUs to run at higher clock speeds, with marginal performance gains at the cost of increased power consumption, which for a laptop means the battery has to be charged more often, shortening battery life.

    AMD has developed a new architecture they call Ryzen/Zen, and claim they will be releasing later this year a more architecturally efficient desktop CPU and faster clock speed than the Intel i7 line, with no appreciable increase in power consumption. I haven’t yet seen any technical web site that has received an AMD based Ryzen/Zen system for independent performance testing, to see if the Ryzen/Zen architecture delivers on the marketing hype. I am reserving judgment on the suitability of the AMD Ryzen/Zen for 4k editing until independent test results are in for retail samples of their new CPU. Here’s a report on leaked test results for an engineering sample of the Ryzen/Zen CPU:

    Note that there is an Intel i7 CPU mentioned in the report capable of 4GHz clock speed; a desktop system based on a 4GHz i7 would deliver the optimal performance for 4k video editing and rendering.

    If you can afford to wait, I’d recommend holding off on purchasing a desktop system at least until the new AMD Ryzen/Zen CPU retail versions hit the market because historically, when AMD releases a new and improved CPU, this eventually encourages Intel to discount their prices.

    There is the possibility, which remains to be seen, that AMD may have developed a Ryzen/Zen architecture that may provide the same if not better performance, at lower cost compared with an Intel i7 4GHz CPU.

    For desktop PCs it is possible to purchase stand by power supply systems, to provide backup power in case of a mains power interruption.

  3. Hi Neilrued,

    Thank you so much for comprehensive answer to my question,it help me a lot in my
    thoughts.Slow rendering and graphics card was the reason why I was not sure about
    this laptop.
    In the meantime as an alternative I found this:

    You sound like a pro, what would you recommend me ?
    I travel a lot and therefore a smaller screen would be more fit but other one (xps 15)
    seems to be technicaly just right for video is not heavy,only 1.8 kg..
    I’m not pro,just recently get crazy for doing videos and editing them.I post them on fb and
    Vimeo and that’s it,at least for now..

    Or you think that still it will be better to wait with purchasing for a while and wait for better or
    cheaper options ?
