Hello,

I create videos and facing a strange issue. My system usually runs pretty much smoothly except when I render/export video.

The resources are pretty enough related to my work than the recommended system resources by video software (which I use)

Software company recommends:
OS: Windows XP
1GHz+ processor or better
2GB system memory
Accelerated 3D graphics – 64MB ram
DirectX 8.0 or better


Whereas my computer has below resources:
OS: Windows XP Professional, Service Pack 3 (5.1.2600)
Intel Core 2 Duo E4500 @ 2.20GHz
2GB Ram
Graphics Memory: 128 MB
DirectX 9
Intel 82945G Express chipset family (in-built graphic card)
PSU: 400W

My computer runs pretty smoothly with all applications but as soon as I click a button to render a video (to export in either mp4 or avi or any format) the CPU load goes to 100% until I stop the process.

The same thing happens no matter which video creation software I use. When I open the software, arrange media till that time everything remains normal but as soon as I try to create (export) a video the CPU load goes to 100%

For your convenience Here is my complete system information:

Hardware Info Detail: https://www.dropbox.com/s/2lts8g7yi4phqzc/Hardware-Info-Detail%20.txt?dl=0
Graphic-Summary: https://www.dropbox.com/s/ghbuyne4mxpatl9/Graphic-Summary.txt?dl=0

Could you please tell me how to fix this issue?

Thanks

Everybody's CPU goes to 100% when rendering video....
The more powerful your processor is, the quicker it completes the render.
I have a quad core PC running at 4.2Ghz... twice as many cores, at almost twice the speed, means I could complete the same video render as you in one quarter of the time

You would definitely benefit from a newer more powerful system. Something like an i5, i7, xeon or fx 8350 with 8-16gb of ram, a discrete graphics card with a bit of horsepower (not onboard graphics which can barely get images from the pc to the screen) and a couple of hard drives. Possibly an ssd as a boot drive for the operating system and program files and the source file and another hard drive to write the rendered video to.

Regardless of which cpu you have, if you're using cpu rendering to render the video (as it's actually being created) it will jump to 100% and use all it's got. Video creation/rendering is one of the most demanding tasks on a pc, even a brand new one.

All the replies are much appreciated. Let me first start with @lodders
Thanks :) Yes, I also doing research at my end every single day.
If I consider going for a new PC then:
In your signature, it's mentioned you use 'stock cooler'. is it because you're using overclocking processor 4690k? If so, in case if I don't go for overclocking then don't I need 'stock cooler' or similar?


2. You're using SSD 240Gb. Is it better than 500 GB SATA WD in terms of performance? Someone told me that SSD has less life span because it gets out of order fast as it runs so fast. Do you know anything about this issue?

3. How do you decide which Motherboard is best and going to give optimal performance for our desired CPU. Lets say if I go for Intel i5 6600 or if I choose Intel i7 6700 then what should I do to choose the best motherboard?

Your opinion will be much appreciated.

An SSD is five times faster than a conventional hard disk drive. Makes a big difference to speed of the PC
Apparently SSD last longer too. Need to wait a few years to find out if it is true, but no problems so far...

The stock cooler is the one that comes free with the CPU. It limits the amount of overclocking that you can do, as does the simple motherboard which I chose. I could have done 15% bigger overclock, but only by spending more on cooler and Z87 motherboard - not cost effective IMHO
Another way to get more speed is to buy a Skylake processor and motherboard - 10% faster, more modern, and predictably, more expensive....

My motherboard is low priced from a respected manufacturer. Reviews show that it is capable of running any intel CPU. No speed difference between cheap and expensive motherboards except overclocking potential. Low price reflects limited connectivity and features... manufacturers website will allow you to compare features if you need more.

You can get faster CPU than mine, which will render quicker... but you are spending more and more money for less and less extra performance. Mine is very good value for money. Depends how valuable your time is.

If it's a work pc where video creation is more than just an occasional task or is a source of income where time is money I'd suggest either a xeon 1231v3 or an i7. I also have a 4690k and it renders video well enough but I don't do it that often and it's not my source of income. Hyperthreading can make a noticeable improvement when it comes to video rendering.

What software are you using? It might help assist in sorting out your hardware. Adobe premiere pro, sony vegas..?
