Computer settings for video rendering?

Question

Iron

What computer parameters are responsible for the fast rendering of the sequence?
What parameters of the processor, RAM, video card should I pay attention to?
I was looking for off. documentation on Sony Vegas, Premiere Pro, After Effects and their interaction with hardware, I did not find.

Answer 1

The processor needs to look at the number of cores and frequency, but it’s better to also look at tests, for example i7-5960Xoverclocked to 4.2 (works stably at this frequency), better than E5-4650 , performance comparison . Considering their price difference, the i7 is out of competition (performance comparison) . That is, it makes sense to take processors more expensive only if you have the task "Render faster, budget> 10,000,000", where you can build a whole render farm.
The memory frequency must be supported by the processor, it is written in the characteristics of the processor, for DDR4 It is 2133 at the moment.
It's also better not to forget about hard drives, it's better to take 2 (RAID 1) or 4 (RAID 10) WD Re hard drives. The smaller the volume, the more reliable, but if there are 4 pieces, then you can take it for 4TB.
As a video card, or a new Nvidia Quadro series, but they are expensive, the price / performance is better than 980.
It’s hard to say something about the characteristics of a video card now, they can only be compared within 1 line and one generation, which is for sure, the more memory there will be the more scenes will fit.
Almost all programs support CUDA, this is the NVIDIA software environment, if you are going to simulate a lot of liquid in RealFlow, then you need a video from AMD, they have better OpenCL.
You can read a little about CUDA, it speeds up rendering and video processing quite a lot if the program supports this technology.

Answer 2

It is also very important to have a large disk space, with a good speed of writing large amounts of data.
Once upon a time, it was necessary to have a video capture board, but now it is not relevant.
But for hardware transcoding and video rendering, you need hardware acceleration - specialized media controllers.
But lately, most programs allow you to use gpu video cards for rendering, so a good video card with a lot of shader pipelines and memory will not hurt.

Answer 3

The best option for video rendering would be the GC - Qudro, but it is very expensive. Otherwise, the better, the better) Although in any case, the CPU (i7-i7extreme or multi-core AMDs are preferred) plays a more important role. You can render in general with one processor. But the work during the creation and processing of the project will again be terrible, so look for a video card with a large amount of memory. In general, it all depends on your budget and needs (namely, the volume of projects with which you are going to work)
And since your entire project is compressed into memory, the RAM is also not unimportant, at least I advise you to start with 16, the best option would be 32. I have 8, and believe me, this is the worst thing that can happen with video processing - not enough RAM.
