i have a cooling pad, fans set to max, a 120MM fan on the back, and in an air-conditioned room
here u go
Got a tip for us?

Still waiting to see a screen shot of Activity Monitor doing this "normal stuff."
Even if you do find a way to do it and add a significant increase in speed, your cooling setup will be insufficient. You're going to need a special rig setup with liquid cooling or a massive heat-sink with a large CPU fan. That's what PC users usually do, myself included when I used to do that. Laptop's aren't the ideal thing to OC. You might be able to pull it off if you use it inside a freezer. But then the HDD might not work too well in the extreme cold.
This is a typical PC setup for cooling an OC'd CPU and this guy went from 1.8GHz to 2.8Ghz. He's cooling his CPU & chipset.

I think you are overestimating the possible performance gains.
If something is so slow that it's actually unusable, overclocking a few percent won't change that.
I also think you're underestimating the performance of your machine. A 2ghz Penryn is perfectly fine even for rather demanding tasks.
If your machine is really as slow as you describe, it's probably a software problem (or a crappy/failing hard drive).

Lol don't bother trying to OC if you think that is cooling
... I OC'ed my i5-2500k CPU by 1.2 Ghz and that was with a the Hyper 212+, great cooler for the price. Laptops don't have the heatsink, cooler, or design to OC well. IMHO it's just plain stupid to OC a macbook pro that already sucks with heat. Go buy a new computer b.c OC'ing won't solve your problem. It will prob make it worse by either A. making it too unstable or B. you break/fry something.
Okay, so it is an aluminum MacBook. Why couldn't you just tell us that?
Most will not help you because you act like a toolbag. Some people are giving you good advice in spite of that fact.
Asking questions on a forum is a form of discussion. If you just want a simple answer, learn how to use the Googles. No one owes you a bit of time or respect based on your attitude. I am not trying to rip on you, just letting you know since self-observation is hard for some young people (assuming you are young). You will learn more if you learn how to interact.
googling only gives me the ZDnet overclock for mac, which is mac pro only (it'll be great if they release the universal version tho...)
i'm not young btw
EDIT: there's a app named coolbook, is there any way this can be used to OC?

Here is how it's done.

Have a look at Activity Monitor (Applications / Utilities /) and select All Processes and sort by CPU to see what the culprit may be.

As been said before, OC'ing a computer especially a laptop is pretty pointless. The cooling in your MacBook isn't designed for it.
Best bet upgrade to a newer laptop or build a cheap multi-core PC to do the rendering.

i don't think firefox with 8 non-flash tabs will take 30%
then again, i have a old mac
If when you followed those instructions, Firefox appeared at the top of the list with a CPU usage of 30%, then yes it is.
Can you post a screenshot of Activity monitor after selecting all processes and ordering by CPU %.
CoolBook is only for undervolting, it does nothing with clock speed. That said, I love me soon CoolBook; 10*C cooler temps under full CPU and longer battery life.
I wouldn't suggest it, but...
Alright look, no one really recommends doing this, and neither do I. You will literally cook the living piss out of your MacBook, Unless you have liquid nitrogen running through your computer.MacBooks run hot enough already, I wouldn't want to see what it's like after being overclocked.
However, if you feel it absolutely necessary, there is a shareware app you can use to manually adjust your clock speed. I honestly don't know anything about it, or how to use it. But, it has a good rating on MacUpdate. Here is the link: http://www.macupdate.com/app/mac/23183/coolbookcontroller
Good luck with the second and third degree burns that will soon follow...

...which means overclocking won't help at all in this case.
Seriously: What do you expect?
For example: You MacBook is able to run a game at 10fps now, even with a 20% performance gain through overclocking (which would be a lot for a notebook), the game would then run at 12fps and still be unplayable.
You're talking about it like it was an old PowerBook G3.Core 2 Duo machines are still being sold today.
In all seriousness, TC, post a screenshot of the activity monitor with the CPU tag clicked, so the most intensive tasks show.
As everyone here has said, overclocking is not the solution. If you REALLY think the machine is at fault, sell it, and purchase a new Mac.
Thanks, I didnt think Id have to tell him how to post in Activity Monitor.
OP, obviously you have something taking a lot of %CPU, since your %idle is 55%! Thats terrible. Just fix the offending app (might just be a plist file needs to be deleted), and forget about OCing.
You tell him!
In my opinion, some people just need to experience the consequences if they are not willing to listen to the advice coming from the majority.
It goes back to the "I told you so" saying.
I would be a troll if overclocking a mbp was something plausible. The video was telling the truth, that overclocking a mbp is not going to happen.
We dont even have a bios to overclock like windows computers. Apple does not condone overclocking and when you got a forum of people telling you that its not plausible, its not going to work. Overclocking a mac pro is possible but overclocking a laptop (especially a mbp) is really dumb.
You might be able to overclock your graphics card depending which 1 you have but your cpu is out of the question. Even if you did get it to work likely it would cause many more problems and make your laptop preformance drop due to the heat.
There is a reason Apple and other laptop manufactures do not let consumers overclock laptops!
A high idle % means that nothing is requesting more resources. So over-clocking wouldn't help in this case as the full power of the machine isn't being used as it is. You'd just end up with slightly faster idle CPU cycles (and the aforementioned meltdown, quite probably).
A possibly more relevant question is 'how are you importing the video'? If the source is a USB hard drive, flash drive/card, firewire drive or other connected device, then the slowness is very likely in the transfer, not in the horsepower of your laptop. Especially if the file is large and being transcoded as it's ingested.
If it is an external source, then you're limited by the speed that device can transfer the file. And then there are other possible slowdowns (is it less than a class 6 card? is it a 5400 rpm drive? is it a USB 1.x device? etc.)
Another possibility, if it's not an external device that's slowing you down, is a problem with your internal hard drive. But you can find that out quickly by running Disk Utility, clicking on your Macintosh volume and clicking 'verify disk'.
One other possible culprit is that the program ingesting the video is not multi-threaded and can, therefore, only use one core of your multi-core CPU.
Good luck. But, again, over-clocking is not what you need.

Unbelievable. He asks how to delete a plist and hasnt even told us what AM gave him. Hopefully, he doesnt delete something he shouldnt.
