构建用于视频编辑的PC

图像

视频编辑PC不像您的典型游戏构建。尽管它们共享许多组件,但这种类型的构建需要更多地关注处理和快速存储图形马力。以下PC构建应达到照片和视频编辑的目的,甚至可以执行比普通计算机更好的3D建模。请注意,我们将专注于拥有合理价格的组件,而不是建议并非每个人都能负担得起的一流商品。

中央处理器:英特尔核心i7-4770k

The CPU is the most important element in an editing machine. Slower CPUs take longer to finish tasks, wasting your time and resources. Because editing is CPU intensive and multi-threaded, it is important to get a powerful CPU that can handle as many threads as possible. An Intel quad-core with hyperthreading is the minimum for a serious editing machine, and going for a hexacore is perfectly logical too. Unfortunately, AMD’s hexacore and octocore CPUs do not match the performance of the Intel CPUs when it comes to video editing, even though they have a similar core count and a lower price.

The Intel i7-4770K runs off their latest CPU architecture, Haswell. It is currently their flagship processor and contains four cores which are hyperthreaded, meaning that they can process up to eight threads at any given time, which is crucial to many editing processes. At the time of unboxing it will be clocked at 3.5 GHz with a turbo clock that reaches 3.9 GHz. This said, it can be over clocked higher since it has an unlocked multiplier due to it being a member of the K series of processors. If you are reading this blog post late, you may look for the i7-4790K, which is an update to the i7-4770K, and is expected to be available for purchase towards the end of June 2014.

Alternative CPUs: Intel Xeon E3-1230V3 (also a quadcore with hyper-threading, but cannot be overclocked), Intel i7-4930K (6 cores, 12 threads, needs a 2011-socket motherboard)

母板:华硕Z97-A

Since this is a Haswell build, it is of course necessary to get a build that has an LGA 1150 socket and supports the chipset. This is an extremely full featured board for the price, containing USB 2.0 and 3.0 ports, SATA 6 Gb/s ports, and four DDR3 RAM slots, allowing plenty of room for upgrading in the memory department. All of these high-speed storage interfaces will help to make the editing process as fast and smooth as possible.

内存:16GB(2×8 GB)DDR3 RAM

RAM的品牌只要在1600 MHz以上时钟,就像非常好的Corsair Vengeance系列一样,它并不重要。RAM是构建用于视频编辑的计算机的最重要部分之一。大多数编辑程序,例如Sony Vegas或Adobe Premiere,都将使用尽可能多的内存。使用两个8GB棍子,如果您决定想要更多,则可以选择升级到32GB。

GPU:GTX 960

从历史上看,图形卡从来都不是编辑计算机中最重要的部分,因为渲染过程主要是CPU密集型任务。但是,有一些使用GPU的GPU加速任务,并且拥有良好的GPU意味着PC也可以用于编辑和游戏,如果您愿意。

此外,现代编辑计划已开始利用GPU性能用于实时渲染应用程序,例如Adobe Premiere的Mercury播放引擎,该引擎对编辑平滑度有很大的影响。

The Nvidia GTX 960 fits this bill perfectly due to its large number of CUDA cores (Nvidia’s proprietary CUDA technology has more support in the video editing world than the open standard of OpenCL), large 256-bit memory interface and 2GB of VRAM with greater support for high resolution workflows.

这个可以被交换出去GPUof lower or higher cost (such as aGTX 750 TI少100美元),因为您可能会在其中进行的游戏数量可能会有所不同,并且仅坚持使用集成图形,而Haswell基础架构可以大大改善。但是,GTX 960是一张出色的卡,价格合理。

SSD:240GB或256GB(Sandisk Extreme II或者三星840 Pro)

Not every build requires a SSD, but in the case of editing, the extra speed can certainly help if you install your editing software on the drive. Along with this, the SSD doesn’t need to be very large since you should have little issue storing all of your editing software on 256GB. Please note that this is a guide for a reasonably priced PC, and having a 1TB SSD for $500 extra is considered perfectly viable for those who insist on editing only from the SSD.

Keep in mind that you will likely still need hard drive space for storage and archival, and that SSDs will generally wear out faster than HDDs under heavy workloads.

贮存:1TB(西门特梭子鱼或者WD黑色)

Input/Output performance is the most common bottleneck when it comes to video editing, and due to the fact that the price-to-storage ratios of SSDs have not yet reached the level of hard drives, we recommend a multi-drive setup. Refer to本指南有关磁盘分布指南。3驱动设置是一个强大的起点。

当将SSD作为系统的“ OS驱动器”结合使用时,您可以获得两全其美的最佳状态,因为您仍然可以在拥有大量数据存储的同时获得快速的启动速度。Seagate梭子鱼是实现此目的的理想驱动力,并且在一个Terabyte上有足够的存储空间,但是如果您需要更多,则可以轻松升级。WD黑也是一个不错的选择,比Seagate具有更好的保修,但价格更高。

测量驱动器性能的绝佳工具是Blackmagic Design的磁盘速度测试应用程序,可作为其驱动程序包的一部分可用这里。它为您提供有关I/O可以处理哪种视频数据流的快速简便参考。

PSU:季节性M12II 620

This power supply is fantastic in any build. 620 watts of power will by more than enough to get this rig running up to speed and the 80PLUS Bronze Certification means that its high efficiency will keep it from jacking up your electric bill too much. Lastly, its modular nature means it will be easy to assemble the computer and organize the parts within the case.

CPU Cooler:冷却器大师超级212 EVO

这位风扇是当之无愧的声誉,这是最好的散热器之一,这是有充分理由的。它非常便宜,提供了很棒而安静的冷却,不会破坏银行。它的通用安装解决方案还确保它将与主板和此版本中的其他组件一起使用。

Case:Rosewill R5

This case is a great value for its price point. Its three fans will ensure a good amount of cooling. The dust filters also help to ensure that your case will remain relatively clean and free of particles that may hurt other components. It also has 6 internal drive bays as well, so it can easy support both the SSD and hard drive with space to add even more storage if desired. Along with this it has three USB ports, including one that is USB 3.0. Lastly, it supports ATX motherboards, so it is compatible with the other components.

There are, of course, components other than these that are necessary to build a great PC, such as the operating system and peripherals, along with various other options such as an optical drive. However, the parts within this build will put you well on the way to having the hardware of your new editing PC sorted out. If you need help choosing peripherals, such as a mouse or monitor, be sure to check out the Logical Increments peripherals guide.
