I noticed that while encoding Hancock (not a great movie) that my CPU was being totally used up by Handbrake. I am on a new MacBook (Late 08" 2.4Ghz). Have any of you had this experience/ is it normal?
 
Don't worry about it using 100%. It doesn't prevent other apps from running ... it uses what's available after other programs grab their resources.
 
Alright Cool,

So a Quad or "Octo" core would just encode a crap load faster than a regular old dual core at the same clock speed. The encoder app will encode as fast as the processor lets it, is this correct?

So basically a Quad would encode twice as fast at the same clock speed, and an 8 core 4 times as fast as a dual core at the same clock, right?
 
Using iStat Menu it shows CPU activity per core. Handbrake uses both cores on my iMac, and it nearly pegs them while encoding. As mentioned before - it's a good thing, as older programs I've used in the past incorporated only 50% of your CPU - they took a while.

Does Handbrake support 4 or more cores? IDK, but sure would be nice (and a tempting reason to upgrade) if it did. :)
 
How can you tell if Handbrake is using 1 or 2 cores? Activity monitor shows almost 100% of the processor being utilized.
Handbrake I believe will use a maximum of 4 cores. If you want to use 8 you can right click on Handbrake in applications and go to duplicate, and run two instances of Handbrake and have each instance use a CPU to encode 2 DVD's.

The duplicate tool is extremely useful and works for alot of applications to run multiple instances of an application.

lol it supports 4. at least it does on mine though i might be an exception

I'm sure once Snow Leopard is out, we'll see Handbrake become lightning fast.

that would be super nice! i hope the gpu can use these calculations to help out with handbrake
 
I would like to hear for someone on a quad core machine. Does it do the same thing?

I have a Dell Quad-core (Q6600) running at 3.0Ghz and it pegs all four processors as well, it's normal - if it's working right it would peg a dual Quad-core machine as well, only for a shorter period of time.

Usually I can rip a movie to the AppleTV preset in about 35 minutes with the machine.

I found this thread though because of the 'Hancock' reference as that one is giving me trouble. Ripped the DVD just fine but Handbrake really struggles with it and the process dies after like 600k is written.

Anyone figure that movie out yet?

I have it ripped and encoded to H.264 and I had no problems.
 
i also ripped Hancock with Handbrake, and it took a while ~2hrs.

Sounds about right. Encoding is extremely CPU intensive - especially when encoding using H.264.

The CPU usage should be 200% in Activity Monitor - since there is two cores. You can always tell if both cores are being used by an application by how much CPU power it is taking up. If it is over 100%, then it is using both cores.
