Part 3. What Computer Can Edit 4K Videos?
Only with the help of the best 4K video editor, this is not enough. We also need the qualified hardware configuration of the computer. So to put it more bluntly, what kind of hardware, like the RAM, can help us edit 4K videos much more smoothly?
The RAM I/O performance
I/O (Input/Output) performance refers to the input and output of data, or the flow of data per second. The amount of data in 4k is very large, 4 times bigger than that of HD. Obviously, it would be a big challenge for the RAM. So we need to make sure that the RAM is powerful, and with great I/O performance. But how to decide this? When we choose the RAM for 4K editing, we can simply check its frequency and dual-channel feature.
This page gives detailed information about the best PC build for 4K video editing.
Many people say that memory is one of the most important computer requirements for video editing. We are not going to deny it. Especially for the low-configuration computers, the most important part that needs to be upgraded is just its RAM. But how much memory do we need for 4K editing anyway? The more the better?
The requirements of computer hardware vary greatly when using different 4K editors.
However, the memory capability is not all about the ability of RAM for 4K processing. We need to check more other specs about the RAM.
2. RAM frequency
In addition to requiring large memory, RAM with better I/O performance also requires a higher frequency. The higher the frequency, the better the I/O performance of the memory. The same amount of memory, such as the 8GB ones, some are much cheaper than others, and some are quite expensive. One big reason lies in the frequency. Generally, for 4K editing, it is OK to choose the 2666MHz or 2933MHz memory.
3. Dual-channel memory
The dual-channel feature can also upgrade the memory I/O performance. The benefit of dual channels is that the memory speed can be multiplied. Because dual-channel memory increases bandwidth, and hence, it improves data processing.
But you need to notice these,
- The motherboard should support the dual-channel.
- The CPU must also support the reading of dual-pass memory, such as 8700K, 9900K, and 3900X.
- You need two memories. Choose the same model of RAMs to avoid incompatibility.
Surely, the computer hardware configurations are not just RAM. There also include GPU, CPU, motherboard, hard disk, etc. which we will need for 4K editing. And if you want to learn more, here we have prepared a detailed page about hardware for 4K video editing, to which you can refer.
If you have high computer configurations, use renowned editors like Premiere Pro for any 4K or HD videos. But for slow and old computers, advanced editors make things times slower. VideoProc Vlogger is suitable for regular computers, as it relies less on CPU and RAM. You don't need to close all programs down. Instead, it allows extra juice for other activities running at the same time.
Part 4. 4K Video Editing Tips
Editing a 4K video should be nothing special. You can do it without a 4K monitor, or without a powerful computer. But some users grumble at stutters, crashes, and computer glitching out when importing, editing, playing back or rendering their large 4K projects on some video editing software. Here are some tips on how to edit videos smoothly on slow computers:
1. Do not install the large professional NLE system on your Disk C.
You should ensure the system disk have sufficient space to be efficient. Otherwise, your computer will not run smoothly.
2. Choose a video editing software that has lower requirements on your hardware.
From the review above, VideoProc Vlogger (for Windows and Mac), iMovie (for Mac, iOS), Vegas (for Windows), Corel VideoStudio, Lightworks (for Linux, macOS, Windows), Shotcut (for Linux, macOS, Windows) and VSDC (for Windows) meet this criterion. Among them, VideoProc Vlogger is free and light and has a low requirement for hardware. It provides frame-by-frame precision when editing footage, and handy templates and filters to use in 1-click. You can learn more tips on how to edit 4K videos in the simplest way.
Note: Some software has a version to run on a 32-bit computer, but it is not suggested to edit a 4K video in a 32-bit system or program.
3. Turn on hardware acceleration.
Since 4K video editing relies heavily on graphics processing, you should make good use of the NVIDIA, AMD/ATI, or Apple Metal graphic card power on your computer. For example, it is suggested to turn on your Hardware Acceleration on Windows 11/10 when editing the 4K video. By moving all graphics rendering from the Central Processing Unit to the Graphics Processing Unit, it will get faster and achieve better performance. Better still, most editing programs have the ability of hardware acceleration. Just choose a suitable one. For your reference, VideoProc can make FULL use of your CPU and GPU resources, and you don't need to do any settings.
4. Split your 4K video into clips and edit them one by one.
If your computer is very old and slow. This method is recommended if all the three above are not working. Cutting your lengthy video into pieces and merge them after you complete the editing. This can avoid the crashes and data loss somehow.
5. Downsample your 4K video to 1080p or 720p.
This may be the last resort. But don't worry if you plan to upload the 4K video to YouTube, Instagram or other social media platforms. 1080p is enough for social sharing and reviewing on a mobile device.
Part 5. 4K Video Editing FAQ
1. How much RAM do I need to edit a 4K video?
- 16GB of RAM: Good for editing 1080p – 4K 8bit Projects, with minor usage of background programs.
- 24GB RAM: At least is OK for 4K material editing, and if your budget is sufficient, 32GB, and even 64GB would be much better.
- 32GB of RAM: Good for any type of editing with heavy use of background hogs, such as editing large images in Photoshop.
- 64GB or more: Recommended for editing 8K footage in 10bit or more and RAM-hogging programs such as After Effects/Cinema 4D.
2. Is there any 4K video editor online?
Yes, there are some 4K video editors online, such as Kizoa. Although most of them seem to support 4K resolution as input, seldom of them can output real 4K quality. The image quality will be downgraded automatically. 4K video file is so large in size that the requirement of your internet connection speed is very high. So it is not suggested to edit an UHD video online.
