Jordy here for cinecom.net and welcome to creative Tuesday.

In this episode we're taking a look at all the details...

...on how to build your own 4K video editing computer.

Before we start, I'd first like to thank MSI for sponsoring this video.

They have provided us a system with the latest hardware...

...that suits perfect for video editing tasks.

We'll use this hardware as a reference, however the goal of this video...

...is to inform you about what to look for in the different components for video editing.

And that way you can make your own choices...

...that will fit within your budget or preferred brand.

At all times you can visit the first link in the description below...

...to learn more about this system.

They have put up a nice webpage with extra videos....

...and in-depth information about each component.

Now, building a computer for video editing is a little different from a gaming pc.

You wanna spread your budget correctly over the components,

so that you can take the maximum performance out of your machine...

for the tasks that you do.

One of the biggest misconceptions is the graphics card.

It plays an important role, though, but it's not the most important.

That is the processor.

Modern video editing tools like Adobe Premiere Pro and After Effects,

Sony Vegas, Resolve, etcetera, are designed to utilize the cores of a processor.

Having an 8-core processor means Premiere Pro, for example,

can perform multiple calculations at the same time.

And that's also why the processor speed is less important than it's amount of cores.

You'll get much better performance from an 8-core running at 2.5 GHz

than a quad-core running at 4 GHz.

So I would always suggest to get as many cores as you can.

It's even possible to install two processors in the right motherboard,

which could give you easily up to 20 cores or even more.

Do however check your video editing software first

to see if it's compatible with a dual CPU...

...and the amount of cores you're about to install.

Always remember that the software is the weakest link in your setup.

Our system came with the Intel i9-7900X,

which is a 10-core CPU running at 3.3 clock speed.

This is a beast of a CPU and it's giving us extreme performances...

...inside Premiere Pro...

...and when exporting a project.

You can see it very good in the task manager how Premiere Pro is utilizing each core.

Of course, this is a more expensive CPU.

The great benefit of it now is that the CPU is future proof.

But an Intel i7 will definitely work superb too for 4K editing,

and there are even a few i5 processors that I could recommend that have 6 cores inside.

I would not go below 4 cores, unless you're not planning to edit 4K footage any time soon.

Ideally you wanna sit around 6 to 8 cores.

Now, having a large multi-core processor in your system comes with a flip side,

which is heat.

Make sure to keep some money over for a decent CPU cooler.

For high-end processors I would even recommend to go for a liquid cooler.

Cooler master is a very popular brand for these,

basically they have their fans up in the case blowing the hot air directly out.

And this hot air comes through the liquid,

which is being pumped from the processor to the fans.

Speaking of cooling, your case is an important factor here too.

MSI Send us a very awesome looking case,

with big LED fans on the front which you can even change the colors of...

...and a glass cover on the side.

This one also came from Cooler Master,

but of course a fancy case will not help you to get better performance.

The number one reason that you should choose a case is for the air flow,

the second reason could be the looks.

To find out if a case has a good air flow, look at the fans it comes with.

Ideally you wanna have a fan on the back and on the front.

One of them should suck the air in and the other one blowing it out.

Only then you have good air flow.

The larger the fans are and the more you have,

the better your air flow will be.

And of course a last point to pay attention to...

...is that all your other hardware will fit in it.

Alright, next on the list is the graphics card.

Modern editing software is able to utilize the graphics card more...

...and better these days,

but still is a fraction of what a GPU is capable of.

In Premiere Pro you can actually see a symbol next to the effects...

...that can be accelerated through the graphics card.

This means that you can apply and even stack effects...

...on a clip which can be played back in real time.

The same thing goes for Color Grading inside Premiere.

But all the rest of the effects will use 100% of the processor to render.

When searching for a graphics card, one of the first things you'll notice...

...is the memory it comes with.

And for video editing, don't mind this too much.

Video memory is needed for animations and 3D modeling,

for video editing I wouldn't spend extra money on just some more VRAM.

What is important, though, is the amount of cores in your graphics card.

Nvidia calls these CUDA cores and AMD Radeon cards have stream processors.

They are essentially the same but are built upon a different technology.

AMD cards use OpenCL and Nvidia have their own CUDA technology.

The more of these cores you have,

the better performance you will see in both playback and rendering.

I would suggest to get at least 1000 cores...

...if you're looking into editing 4K footage.

And then there are the different technologies that the graphics cards comes with.

For example, if you would like to edit in virtual reality,

then you have to make sure that your card supports that.

MSI provided the GTX1080 to us.

It's a beast of a card but, honestly,

we're not seeing much difference between the 1070 or even the 1060...

...we also have at the office.

That again proves that the processor is the most important part within the chain,

which we do notice a big difference from

between the various processors we have.

When you're searching for a graphics card,

you'd probably find various brands providing the same Nvidia card.

The architecture is always the same,

but the difference sits within the cooling of the card, LED lighting,

factory overclocking, etcetera.

What makes the MSI card stand out is their cooling design,

which they also won a price for.

You can find out more again by following that first link in the description.

Next up comes the memory.

There's this general rule of having at least 16 GBs for full HD and 32 GBs for 4K editing.

Now, does having more RAM means rendering will go faster?

Not really. To a point there is,

but that threshold sits around 8 GBs of memory, maybe.

Further up, the performance is barely noticeable.

And if you wanna see a full test of that,

I'll leave a link to Max's video in the description below.

He even found out that having too much RAM in your system...

...could slow down rendering time.

But then, why do I recommend to have so much memory?

Well, usually you're not solely working in your video editing application.

You might be going back and forward between After Effects, Photoshop,

your web browser, Premiere Pro and a bunch of other applications.

Well, every single one of those applications...

...is going to need some working memory.

And this memory is being used to write temporary actions to

that are needed by the program.

You could essentially use a portion of your hard drive as memory,

but that will go super slow.

And that is why the speed of the memory is an important factor.

These are the megahertz displayed on the dimms.

The MSI build came with the HyperX Predator memory.

These are DDR4 dimms, which is the latest technology,

and offer great speeds.

If your budget allows that, definitely go for DDR4 memory,

DDR3 is definitely not bad, below that I wouldn't go.

That brings us to the next component, which is storage.

It's pretty straight forward,

the more you have, the more video you can store.

So that's something that you have to decide for yourself.

But knowing that there are many different storage options,

it's worth to talk about.

There're mainly 3 categories:

you have the normal hard drives,

the SSD's and finally the M.2 SSD's.

And the difference lays within the speed of the storage.

Does that mean we have to look for fast storage?

Well, not exactly.

It's not going to help much with the performance while editing or rendering.

And that's why I would even suggest to go only for a traditional hard drive...

...if you're on a small budget.

When you do have some more money to spend,

look at a combination of a traditional hard drive and an SSD.

SSD's are super fast, which means that your computer will startup much faster,

programs will open up a lot faster...

...and you can drag media around a lot faster.

But it comes with a price tag and as a video editor...

...you probably need a lot of storage.

And this is why I would recommend to install your windows and applications...

...on a fast SSD.

And your media on a hard drive.

For an even faster experience you can go for an M.2 SSD.

These are chips which install directly onto your motherboard...

...and have tremendous speed performance.

Our system came with the Intel 600P M.2 SSD,

of 256 GB storage,

which is enough for our operating system and all the applications.

It's a beast of a storage with read speeds up to 1.5 GBs per second.

As for the media drive, we got the Seagate Barracuda Pro.

It's a 10 terabyte drive designed for creative tasks.

It runs at 7200 rpm, which eliminates any delay during rendering.

But you could also go for a 5400 rpm drive,

if that fits better within your budget.

But, again, remember that you don't need an SSD.

It's a luxury,

once your Windows is booted and you have started up your editing programs,

you won't notice much of having an SSD at all anymore.

The final thing I wanna talk about is the motherboard.

Although it just seems like a large connector for all your components,

compatibility is one thing, but...

...utilizing the capabilities of your components is a different story.

If you would purchase fast RAM memory,

but your motherboard doesn't support the speeds,

then you might only be using half of the speed...

...of what your memory is capable of.

So, in terms of budgeting, this is important to know.

If you don't have the money to go for a high-end motherboard,

then also don't spend extra money on a fast memory.

And the same goes for your processor.

If you would look into the specifications of a processor,

you will find the maximum RAM speed it can handle.

Furthermore, you wanna double check that your motherboard...

...has all the connectors that you need,

and that it is compatible with all your components.

If you bought an M.2 SSD,

you're going to need a socket for that on the motherboard.

What I would always suggest is to work together with an IT store.

Let them check your wish list and let them build your PC.

If anything wouldn't work, you can always go back under warranty.

Trust me, it's worth the extra 50 bucks you're paying for that.

Now I have a list to all of the components from our PC...

...in a blog post in the description below.

This is a build that MSI has put together and tested for creative tasks.

We've been working with the system for a month now...

...and it actually runs super stable.

The reason I'm saying this is because some hardware components might work,

but overtime they don't seem to be stable with each other.

They only have a few configurations that are strongly tested...

...and built specifically to work well with their apps and operating system.

Windows machines have a bad reputation because...

...you can put together anything you want,

which, of course, could bring issues.

But having a Windows system that is tested and configured for a specific task

could run just as fine.

Our beast machine was a total cost of $2500,

which is considered to be a high-end system.

In our blog we have also put together a mid-budget and a low-budget system,

which, again, you can find a link to in the description below.

Thank you all so much for watching, if you have any questions whatsoever,

leave them below and I'll try my best to help you further.

Stay creative!

-Hey guys!

You know, I do the most work around here.

So, it's only fair I get the coolest computer.

-Coolest computer?

Does your computer have a door, Yannick?

Look at this, I have a door!

And your computer just breaks apart!

GM races to build a formula for profitable electric cars - Duration: 10:40.

GM races to build a formula for profitable electric cars

What Barra has not explained in detail is how GM intends to do what, so far, no major automaker has done.

The answer is a big bet on combining proprietary battery technology, a low-cost, flexible vehicle design and high-volume production mainly in China, according to six current and former GM and supplier executives and six industry experts interviewed by Reuters.

If GM can meet Barra's ambitious profitability target, then it will house two different businesses by the mid-2020s: A traditional focus in North America on trucks, sport utility vehicles and cars fueled with petroleum, and a global electric car company centered in China, branching into pay-per-use services such as robotaxis.

Barra's promise to turn a profit is a bold claim in a market segment that has been driven more by government policy than consumer demand, and where Tesla Inc - the world's largest electric-vehicle manufacturer - is burning through more than $1 billion in cash each quarter selling premium-priced vehicles.

Barra and GM have invested heavily in the electrification strategy, and worked during the past year to persuade investors that GM can compete with Tesla by building on the success of the automaker's latest electric vehicle, the Chevrolet Bolt EV, and cutting costs along the way.

A key element of the plan, according to two people familiar with the company's strategy, is slashing the amount of cobalt in GM's new EMC 10 battery system.

The price of cobalt – the single most costly ingredient in current lithium-ion battery cells - has soared in the past two years in expectation of a surge in demand from automakers.

Cobalt prices hit a record high this month on the London Metal Exchange.

GM's new battery design increases the amount of nickel, which enables batteries to store and produce more energy, these people told Reuters.

GM engineers are also working on other design and technological advances, according to executives and company patent filings, including more efficient packaging of batteries in vehicles and improved systems for managing energy flow and cooling the battery cells.

Without providing details, GM has said it expects these changes to cut the cost of battery cells by more than 30 percent, from $145 per kilowatt-hour to less than $100 by 2021.

Battery experts said the full cost of a GM battery pack, such as the one used now in the Bolt EV, is $10,000-$12,000, or nearly one-third of the car's $36,000 sticker price.

By 2021, however, that price could drop to $6,000, according to consultant Jon Bereisa, a former GM engineering director who helped develop the Chevrolet Volt hybrid and spearheaded much of the automaker's early lithium-ion battery development.

With improvements in battery chemistry and packaging, Bereisa said, the next-generation Bolt "could deliver a 45-percent increase in range for about the same (battery) pack cost, or the same range at 45 percent less pack cost.

Pam Fletcher, vice president in charge of GM's global electric vehicle programs, and other GM executives would not comment on specifics of the new battery system, which is slated to be introduced in 2020-2021.

To be sure, electric vehicles account for only a small fraction of global auto sales.

Like other manufacturers, GM is banking not only on reducing its own costs and improving vehicle performance, but also on increased demand driven by higher government-mandated electric vehicle quotas in China that are intended to help reduce pollution and the country's dependence on petroleum.

In addition to improving battery and vehicle design and performance, GM is working with Chinese partner SAIC to reduce the cost of assembling electric cars.

Sources said GM and SAIC are designing dedicated electric vehicle factories in China that are far smaller, less complex and more efficient than a conventional car plant.

GM has more capital for electric vehicle development because of Barra's decisions to sell money-losing European operations, exit other unprofitable markets and invest in a new generation of highly profitable, petroleum-fueled large pickup trucks, launching later in 2018.

The automaker now has more than 1,700 engineers, designers and researchers working on batteries and electric vehicles, many of them at the GM Technical Center in Warren, Michigan, where the company opened a dedicated battery research center in 2009, a week after it filed for bankruptcy reorganization.

Automotive experts say GM's battery and EV group is one of the largest in the world, rivaled only by Toyota Motor Corp in Japan and Daimler AG in Germany.

Toyota has patented more battery technology in recent years than GM, although its focus has been mainly the Prius family of hybrid gasoline-electric vehicles, rather than on pure battery-powered cars like GM's Bolt EV.

GM was issued 661 U.S.

patents on battery technology from 2010 through 2015, the latest that such data is available from the United States Patent and Trademark Office, trailing only Toyota's 762 battery patents among global automakers.

In addition to the battery work, GM engineers are developing a new dedicated "plug and play" structure for its next-generation electric vehicles that is flexible and modular, meaning it will be able to accommodate battery systems of different sizes, as well as hydrogen fuel cells, one of the sources said.

In an interview, Mark Reuss, head of global product development, said GM's strategy to reduce battery cost is not tied to a single improvement such as a change in battery chemistry, but rather a series of continuous enhancements in battery technology and packaging.

"There are no silver bullets here," Reuss said.

GM also has not solved all the problems required to achieve its goal, he said.

"It's called 'product development' for a reason," he said.

The most recent developments and enhancements in battery technology have not been made public, according to GM's Fletcher.

"There's a lot of stuff that we choose not to patent because we don't want to make it visible" before the new technology goes into production, Fletcher told Reuters.

LESSONS OF BOLT.

GM's patent history since 2010 shows a focus on improvements in battery technology, packaging and processing, some of them designed to help boost the battery's energy and extend vehicle range between charges, according to company filings.

GM jointly developed its current battery know-how with Korea's LG Group, which makes batteries and electronic components for the Bolt.

Introduced in October 2016, Bolt was the first mass-produced electric vehicle to go more than 200 miles between charges, and sell at a sticker price of under $40,000.

GM sold 23,297 Bolts in 2017.

Tesla reported producing just 1,770 of its $35,000 Model 3 sedans in 2017, well short of the company's original targets.

The launch of the Bolt and its warm reception by reviewers, customers and investors was a watershed event for Barra and GM's top management.

"It was a 'holy shit' moment that made us rethink what might be possible," said one GM insider.
