HD Videography on the Cheap- Part 3: Computers
26 11 2007
Now you have a camcorder and some DVtapes full of excellent video of you running the biggest rapids ever. It’s time to ‘capture’ all that footage and begin editing. For that you are gonna a computer and editing software. This week, let’s look at the computer you need, next week we will get in to editing software.
I will be using the word ‘rendering’ a lot today, and it will come up often when we talk about editing. Rendering is when your computer crunches the numbers. It takes all the footage and transitions you gave it and then makes it in to a movie to show on your screen. In the past we had to do ‘renders’ as a separate operation. The computer took some time… up to half an hour depending on what we asked it to render… then we could look at what we did… then we had to go back and make changes after we saw it.. render it again.. etcetera. Now most rendering happens as you go. We see what the video will look like instantly. We call this ‘real time editing.’ To do real time editing with little or no waiting you need a powerful computer. The less power you have, the more waiting for ‘rendering’ you will have to do.
Is my home computer good enuff to edit my movies?
Chances are that the answer is no. To put it simply.
But, you don’t want to hear that. So let’s do a breakdown.
But my home computer is great! Will it work for now?
As I said when I first started all this, we are focused on HD video… ya, ya, I know.. you want to save a lot of money and buy an old school standard definition camcorder. You are still gonna need a decent computer to edit the film, and a good computer will make your first editing experience more enjoyable. Don’t forget, on top of all of this you will need a DVD burner so you can eventually watch and distribute your masterpiece. (Even better is an HDDVD or Blue-Ray burner so you can watch it in full HD!)
Minimum Requirements
There is a fast and easy way to test if your computer is good enough. Check the minimum specs on the software you want to use. If you fall below any of these, you will need to upgrade. **WARNING** Minimum Requirements are just that.. MINIMUM. Do not expect your computer to run this stuff quickly under these circumstances.
Let’s take a look at Adobe Premier Elements System Requirements. Premier is a decent inexpensive starter program, and will give you what you need to edit together your brother Bob’s birthday DVD.
- Intel® Pentium® (or compatible) 1.3GHz processor with SSE2 support; 3GHz required for HDV
- Microsoft® Windows Vista™ (32-bit only), Windows® XP, or Windows Media Center Edition (XP and MCE require Service Pack 2)
- Windows Vista: 1GB of RAM; 2GB required for HDV
- Windows XP and MCE: 512MB of RAM; 1GB required for HDV
- 4.5GB of available hard-disk space
- Color monitor with 16-bit color video card
- 1,024×768 monitor resolution
- Display and sound drivers compatible with Microsoft DirectX 9 or later
- DVD-ROM drive (compatible DVD burner required to burn DVDs)
- DV/i.LINK/FireWire/IEEE 1394 interface to connect a Digital 8 or DV camcorder, or a USB2 interface to connect a DV-via-USB-compatible DV camcorder
Most home computers aren’t that good, and chances are that if you are investing the money in HD video editing, you are a bit of a gearhead. So, this will be a great excuse to upgrade or buy a whole new system. The bonus is that the computer will be useful for more than just editing.
Interface
You might have noticed that you need a “DV/i.LINK/FireWire/IEEE 1394 interface” This is really important and is one thing that most of us don’t know about. Commonly called “firewire”. IEEE 1394 is a type of interface, not that much different from a USB port. It is standard in most Macintosh computers, but PCs doen’t usually come with one. (That includes 99% of PC laptops) You can install firewire in any computer with a simple plug and play card . At this time, you can get one for anywhere around 30 bucks. Not a huge investment. Currently, I don’t see any available for PC laptops, but I am sure they are available for around twice the price. I recommend that you get a professional to open up your PC and install it for you, as without experience you can damage or break your PC.
This port will be what you connect your camcorder to, and is essential for digital video. Yes… your camcorder has a USB port… no it won’t let you capture your video. The USB port on camcorders only allows you to get any photos you take with your camcorder, and is a bit of a trick on the part of the manufacturer to get people to buy one — thinking all the while they have all that is necessary to edit their footage.
RAM and Processor
Ok… now down to the brass tacks. Your computer will need lots of RAM and a fast processor. The slower the processor, the longer it will take to do everything… but the secret to fast ‘rendering’ is more RAM. I suggest going with a ‘Dual Core’ processor (or two) with a number like 3.0 beside it. As with all things on your computer, the faster the processor, the faster the program will run.
RAM is the real key to making this whole thing work. I would say that 90% of the complaints I get from new editors about their new system comes down to not having enough RAM. For today’s ediitng software you will need at least 2 gig of RAM. I suggest going with 4. Everything runs pretty smooth with 4 gig of RAM.
RAM stands for ‘Random Access Memory.” Your computer uses this memory to access things it needs over and over again. Think of it like this… your hard drive is like a huge filing cabinet. It takes time to get things when you need it. RAM is like your desk… When you need a file, you go get it from the filing cabinet and put it on your desk so you can go back to it over and over while. The bigger your desk, the bigger the file you can keep on it before you have to go back to the filing cabinet.
Video…frame by frame.. is relatively small. But watching uncompressed video, manipulating it, editing it, playing with three or four pieces of video and music adds up. You would need a really big desk to keep all those file folders on, and, in turn, so does your computer. Add in the fact that HD compression is even bigger than SD, and you need the biggest desk you can get. I am talking one of those giant mahogany lawyer sized desk. Editing software will use all the RAM you give it. The more you have, the faster it will get things done. Current editing specific computers can have 16 gigs of RAM and up! Considering that 5 years ago I thought 1 gig of RAM was HUGE… that really is something. (Not only that, if you tell a tech guy you need 6 gig of ram or more he will laugh at you)
Good news… RAM is actually relatively cheap… Often no more than 100 bucks a gig, give or take. So upgrading is usually cheaper than most people think. Since RAM will make an exponential difference in the time it takes for your footage to render, upgrading RAM has the most return for your dollar.
To Mac or not to Mac
Here’s the lowdown. (this is my opinion and may start arguments) Apple makes the best HD video ready computers out there. I am not an Apple fan boy. I resisted buying a Mac for years. I thought of them a pretentious peices of unupgradable junk with a clunky operating system. That used to be true. Now they make a slick peice of hardware that puts my pc to shame and the operating system is perfect for creative software. Best of all, it comes with editing software for free. On top of that, it comes with a firewire port, so you don’t need to install one. Mac laptops are one of the few laptops out there that can run HD video editing software without major upgrading.The only drawback is price.
Macs are expensive. I accept that. But after doing a cost comparison of the ‘Mac pro’ tower, with software included, compared to a windows PC with comparable rigging and buying editing software, Mac actually came in cheaper. So there… take that nay-sayer. One more note on this… Final Cut is the better professional grade editing software. The competition and a few guys who trained on Adobe software will deny it, but almost everyone else would agree. Unfortunately, it only works on Mac. That is why almost every television station has a Mac set up in the editing suite. Final Cut is great, it is easy to use (comparably) and it works. There is nothing wrong with Premeir, it just doesn’t do things quite as well. **we will get more in to this next week**
If you want to save some cash. Buy your RAM after. Apple charges a lot for their RAM. You can get it cheaper if you shop around after you buy your system.
Laptops
Laptops are enticing. Since we are working outdoors a lot and rarely spend a lot of time at home while we are shooting, laptops seem like a great solution. They really are… but there are a few drawbacks you need to be aware of before you buy one as your primary editing system.
No matter what you do, a laptop will be more expensive. Due to the fact that the components are smaller and more expensive, you will need more money to get something that will run your software. Be prepared to spend almost twice as much.
Laptops are slower. Deal with it. Laptops are made to suck less juice out of the battery, be quiet and super small. To do this they trade for speed. You can get close, but a laptop will always be slower than comparable desktops. Be prepared to be frustrated at how long some things will take. That will be the price you pay for having something you can take on the road.
External Hard Drives
The hard drive in your computer is going to fill up fast if you use it to dump all your video to. Instead, invest in an ‘External Hard Drive’. Western Digital makes one called the ‘iBook’ that is up to 1.5 terrabites . It is affordable and works well, some minor technical issues from time to time, but that is to be expected with any piece of technology. Most professional grade editing software actually works BETTER if it has an external hard drive to use as a ’scratch drive.’ HD video requires a fast bus speed on the external hard drive to keep the information flowing smoothly, so get one that uses Firewire 2.0 if you have a Mac with a 2.0 port, or USB 2.0 for a PC.
When all is said and done, your computer is gonna cost about 1/3 of that budget we outlined two weeks ago. I recommend if you are buying a new system, take a good, long look at a Mac over a PC. It will pay off. Make sure no matter what you do, you have plenty of RAM and a large external hard drive. Next week we are going to look at the last big cost. Editing software. (and if you bought a Mac and don’t need professional grade tools, you just saved yourself about 400 bucks)
Stay Tuned…
