Hi there.
As someone who uses Premiere Pro & After Effects CS4, I can provide you with what works best. I will need to know some things first.
1) What video format does your camera use? If AVCHD, you will need the i7. I have a Q6600 overclocked to 3.0GHz and it cannot handle AVCHD very well. The i7 920 at its stock 2.66GHz is about 15% faster than my Q6600 at 3.0GHz.
2) Do you use Premiere Pro CS4 or an earlier version? If CS4, you want 12GB of Ram. Premiere CS4 is now able to use more than 4GB of ram when run on Vista x64. A great article over at DigitalContentProducer.com tests the performance of Premiere with 4GB vs 8GB+ and Premiere's performance was 50-600% faster with 8GB+.
3) What is your budget?
RAID: this is another great way of improving performance and another great reason for using Intel. Premiere has a "media cache" where it stores video and audio from projects. While editing in Premiere, you want to see how your video looks and you hit play. Premiere renders the video and stores it in the media cache. Where the media cache is located is very important to the performance and speed of that rendering. Because Premiere must read the original video and then render it, you want to use 2 separate drives, 1 for the source and 1 for the render/media cache. This is where Raid comes into play. I am going to give a brief overview of what I recommend and why it helps performance.
1) Using 4 drives, lets say 2-250GB drives and 2-1TB drives. The 2-250GB drives split into 2 different Raid arrays: a Raid 1 array for the OS+Apps and a Raid 0 array for page file and media cache. Raid 1 mirrors the data across 2 drives; so, if one drive dies, the other drive still has the data and you lose no data and no downtime resintalling/restoring the OS & Apps. Raid 0 "stripes" data across the 2 drives; thus, about doubling the read/write speed. However, if one drive dies, all the data is gone. The page file & media cache are not important data. In fact, the media cache should be deleted every 2-3 months. Creating 2 different Raid arrays can only be done on Intel motherboards; this is why I said to use Intel.
2) The 2-1TB drives will be used for storage and run in a Raid 1 array to protect your data. The original footage will be stored here. Also, Raid 1 provides slightly better performance when data is being read. Its a process called "Split Seeks" where the OS is able to read from both drives at the same time. Its rather technical, but it does help.
If you don't mind the risk and want better speed with booting up and opening programs, you can just use Raid 0 for the OS, Apps, page file and media cache. If you do this, you will definitely need to create a separate partition for the OS+Apps as C and a D partition for page file and an E partition for media cache. I can help you with the exact sizes of those partitions once we know the amount of ram and which Raid 0 or 1 for the OS+Apps.
I can also provide you with step-by-step instructions for setting up Raid on an Intel board as I have done so for several others.
You don't want onboard video for editing HD video within Premiere. Preferably, an Nvidia video card, such as the GTS 250. When applying Effects, some can use the video card(which must have OpenGL 2.0 support) to render these effects in real-time. More power equals less time rendering. And when you want to see what different effects look like, quicker rendering times help a lot. I like the GTS 250 because it it a dual slot and heat is blown out of the case and it is only $120-30. And the possible CUDA support in future Adobe releases is 99.9% guaranteed because CS4 already supports it but only with Nvidia's $1500 CX Quadro video card.
Back to hard drives: you do not need or want Raid 0 for video storage. The fastest AVCHD can go is a whopping 3 MB per second, which equates to 24megabit. Even Panasonic's $10,000+ cameras only go up to 12.5 MB/s(100 megabit).
I hope I haven't confused you. I have a tendency to do that, which is why I would not be a great teacher.
Hello there specialtalk90,
Thanks for the information you posted. I too am in the process of learning movie editing from HD files. I found your above information very useful. I, as a newbie, have more questions for you, unfortunately.
Firstly my desktop set up is E8600 Core 2 Duo stock clock speed at 3ghz overclocked to 4ghz, graphic card is GTX280, 2GB of DDR3, and one hard disk only, partitioned to C, D, E. This has been my game machine since GTX280 came out. I didn't imagine one day I was going to do any movie editing at all. Youtube changed all that. Operating system is Vista home but will change to 7 very soon.
1. I have 2 sources of video files. 1st is from GoPro HD race cam which outputs MPEG-4. 2nd is from my Sony HD cam which outputs AVCHD files. Both I discovered, very heavy on PCs.
2. I am in the trial use period of Sony Vegas Movie Studio Platinum version (I started to think this is for amateurs, because it degrades source quality, even though it's price at 119 dollars). I had that installed on my laptop (2.4core 2 duo, 2GB ram), and it can't even preview the movie smoothly (at the size of half of a poker card), even at the lowest resolution setting. I know my business laptop is not equipped for such job, but I am traveling, so I am stuck with the laptop. (I am surprised by the slowness of preview window. Then again I tried saving source file at drive D and it sped up) When I go home next week I will try my desktop and see how it goes.
What do you think of my desktop set up?
3. I realized that movie quality changed when rendered from Sony Vegas Platinum ver. Even if source file was MPEG-4 and rendered at MPEG-4 with highest quality available, the quality of the render was lower than source (less sharpness, contrast, etc). Is this software dependent? Are there more powerful software that will not degrade the quality of source file? Do I have to go to the real professional studio softwares, which could cost hundreds of dollars easily (like Sony Vegas Pro at 599 dollars). But then I can't tolerate less than perfect from my productions

Does Premiere Pro CS4 (Adobe?) maintain source quality after rendering?
4. Do I absolutely need 4GB of RAMs to use professional level studio software (well I guess yes)? You recommended 12GB.
5. Budget is not that of a problem. I spent close to 2.5k dollars for that rig, even got a water cooler so I can overclock the graphic card and CPU for gaming. I am not much of a PC gamer anymore but that thing is going to be converted to movie maker now.
That being said, you recommended RAID 1. 1st, for OS and applications, and 2nd, for media files. I understood from somewhere that it is best to have a hard drive for source file, and another for rendered file, also one for program file (the usual drive C). I have to talk to the local shop (I reside in Thailand) and see if they can do RAID 1 properly.
6. OK, so 2x250GB in RAID 1 for OS & Applications, and 2xTB in RAID for storage. I hope that my CPU, which I think at 4ghz is quite fast (can go to 4.2 but unstable), does not need to upgrade to i7. That would probably mean a motherboard change along with other parts all together, and that costs money.
7. What do you think of Windows 7 for movie editing? I've had enough of Vista. A set of no-solution problems with my desktop, and another different set for my laptop. And my laptop lasts 1 hr if unplugged when I work heavy. Sometimes I just want to go for Mac. Is it a myth or truth that Mac computers are better for graphics, movie editing? I suppose at HD level, even the best Macbook pro laptops will have to kneel at the amount of data.
A lot of questions from me today. And that's me. I have a tendency to flood others with this and that, ha.
Look forward to hear from you, appreciate in advance any comments you have.
Best regards,
Sam
