I'm looking into upgrading possibly the cpu. I don't know if I may need a new board?
I have an Intel D945GCCR board with an Intel P4 3.0Ghz XT64 with hyperthreading CPU with 2gb of ram and for standard video sizes and standard definition things aren't too bad with speed. It's when working with these Hi-def pieces from a Flip cam is where the issues arise.
I find that I can only load about 20 or so small segments of Flip clips into any editor and it dumps because of memory issues. I can always get more memory but I don't think this would help with speed much? My board will accept a dual core processor, 2 cores, not sure about 4 or more? I guess a dual core will be better than what I am using anyway.
The slowest of all processes is the deshaking.
I can't spend a lot but anything more current I suppose would be better than what I currently have.

Pentium 4 CPUs are much slower than newer CPUs at the same clock speed... and by slower, it's probably as bad as half speed compared to a Core 2 or Core i7. If you can go to a Core 2 you should see a major improvement in video processing speed.
With regard to running out of memory, remember that there is a 2GB limit for a 32-bit program regardless of how much physical memory you have or whether the OS is 64-bit. A 32-bit program can only safely use about 1.6GB of memory before it risks crashing out due to address space fragmentation. What I would recommend doing first is seeing if you can cheaply or temporarily boost the system to 3GB and make sure the page file is at least 4GB. If the program still crashes out, then either it's not a memory problem or you have a problem with the program or workflow that won't be solved by a hardware upgrade.

Thanks Phareon.
Is Core2 and dual core the same thing? I remember from talk shows I use to listen to a few years ago would separate the terms?
Supported CPUs for my board look to be:
Intel® Core™2 Duo Processor
Intel Pentium® Dual-Core Processor
Intel Celeron® Processor 400 Sequence
Intel shows only 4 compatible types for Core 2:

This is supposedly the best for core 2 that I can get with my current board:
http://www.amazon.com/Intel-Dual-Core-Proc...5/dp/B0015BUFCQ
I would have to save up for a board. It will be a while before I can buy everything needed.
Also can I substitute PC2-4300 ram with PC2-5300? I have Crucial sticks, DDR2, 240 pin, 266hz, currently. |

Just checked and I do have the page file set at 4096, been on custom for a long time actually. So it looks like my best bet is to just get the Core 2 CPU and leave the memory capacity as it is?
Update: How much of an improvement would I get from say going from a P4 XT64 with hyperthreading, 3.0Ghrz to an E4700 Core 2 at 2.6 Ghrz? |

If you put a CPU over the specific described on the motherboard site (higher FSB for example, or also Core 2 Quad), it still may work fine as long as the socket is the same; I have done it myself.
Before doing it update the BIOS, also a beta BIOS if the latest stable is too old.
Maybe before buy ask the store to try, if it work.

Core 2 and dual core aren't the same thing. Core 2 refers to a CPU architecture, while dual core is a generic term meaning two CPU cores in the same chip package. There are CPUs using the Core 2 architecture that are single core, dual core, quad core, etc.
Going from a 3.0GHz P4 to a 2.6GHz Core 2 should be a major improvement. The Core 2 will also throttle down much more gracefully when not at full load.

There is a dual core processor which is truly a dual core such as Pen D 945.
The core 2 duo is a semi dual or quad core.
The performance increase is high when you go to core 2 duo.
But the most improvement comes from the Core i7 2600 processor.
You can overclock the cores to 4.6GHz with no issues.
Combine this with SSD performance, and you have yourself a great machine.
But of course cost brings us back to reality.
I am running Core i7 950 at 4.14GHz and I can do live previews of deshaker at 720.
Anything above that requires 4.6GHz or even more.
Keep that in mind. |

Thanks evropej for the explanations. Cost is a factor for me. I would need to win the lottery to get what I would need, ideally.
You mean to tell me a live 30 fps preview of deshaker at 720!? That's insane! Without any other filters and at 4th scale deshaking I get, if lucky, 2 fps at 864 X 480! 1 fps at full 720!
I'm still getting "out of memory" issues when loading about 8 minutes of Flip video in any of my editors. How do people load full length movies into their computers if this is the case? I've seen people do this even on their laptops and I don't see how with all of the heat and spec issues of laptops.
In task manager when things start to barf I notice the peak memory going to 2.99GB and then just pukes. Is an editor opening up a raw Flip file or it converting it into uncompressed in the editor? Shouldn't the size of the Flip video be the "real" indicator of how much memory is being used? If so then it doesn't seem to be the case with me?
Thanks Phaeron for clearing up the questions on the CPU types. |

I have an Intel DG965WH in my other PC and like you said, the highest CPU that I can use is the E6500. You need a graphics card that supports HD video also. I put my Radeon 2400XT in that PC. Not sure how well it encodes since I don't use it for much. It's just an emergency PC in case this one breaks down.
This PC is a Gigabyte GA-EP35-DS3P with a Q6600 overclocked to 3.2Ghz and 4GB of G-Skill DDR2 1066 memory and it encodes x264/aac pretty fast. My brother's P55-760 I5 runs circles around mine though. I'd like to build a new I5 2500K but the motherboards look pretty lacking. Maybe when the new stuff from Intel comes out then they'll have better boards.
The AMD boards seem to have better offerings and they have a six core processor for around the same price as the I5 2500. |

Thanks DarrellS
I'm looking at AMD CPUs and they seem slightly lower in price. It also looks like the Gigabyte motherboards are cheaper while the ASUS ones are more pricier. I forgot there were more choices than "Intel"
Question is will the newer boards and CPUs, Intel, AMD, GIGA or ASUS take Win XP Pro? I say this because I remember Win2000, which I loved, when trying to put that OS in with the board I put in in December of 2007, same one I am using now, it didn't accept Win2000 because of either some ACPI deal or other incompatibility, can't remember totally but I do remember a blue screen which mentioned something wasn't good with this board accepting Win2000.
I really would like to stick with XP if at all possible. 6 cores does sound kind of nice to me.
In an ideal world I would like to have 8/16 or more cores and have one of these:
http://www.flickr.com/photos/lastfm/2266368081/
But I now remember what Phaeron said about 32 bit programs using around 2GBs of ram only? Maybe that 128GB setup is for a 64 bit system or I'm guessing supercomputer of some kind with special programs to take advantage of that much ram?
A supercomputer would be nice. Probably process a one hour h264 clip in like 10 seconds lol. Vdub on a supercomputer :-) Anyone know of anybody who has tried running Vdub on a supercomputer setup? |

Another thing. A video card. Would this be as much more help so as to free the CPU itself from the chores of processing? I have used audio card before but never had an external video card. |

Here are my suggestions:
1. Look into a core i5 processor, best deal as far as price goes. I would even suggest a 2500 since the mobo is cheaper. Dont get the hyperthreading, it does nothing but cost money.
2. I did an AMD to Core i7 comparison and the AMD lost pretty bad. I have nothing against AMD, just stating facts here, vdub processing was the task. Compressions and deshaker processing.
3. A GeForce 460 or 560 is my recommendation. I say this so you have some support for new features of new GPUs. If you want just video power, I saw 9800 on slickdeals for less then 50 bucks.
4. MicroCenter, google it, has great deals on processors and computer hardware. I suggest an Antec 300 case from them for about 50 bucks.
5. Last but not least, if you want to use more then 3.24 gigs, you must go to a new OS. Vista is crap. Windows 7 has the same crappy interface but runs a bit faster.
6. Get a good heatsink and overclock these bad boys, they can take a 10% overclock with stock fan, 20% with a decent fan, and 30-40% with a good fan.
7. Find a small 40 GIG SSD. This is a must since its the bottleneck in most systems. You can buy the smaller drives for a decent price.
8. Shop around and wait. Deals pop up left and right for memory and drives. But in either case, wait for a good deal.
Good luck in your search =]
