Any way to slow down Handbrake?

[gloryunited]

The question sounds stupid but...

I like to let Handbrake take care of some batch-converting overnight while I'm sleeping. However, it's better to lower the CPU usage so that my MacBook Air fan wouldn't be running at 5000+ rpm while I'm sleeping besides it.

Is there any way to allocate or throttle CPU usage? Is it possible for Handbrake to convert in a slower and less CPU-intensive rate?

Thanks a lot.

Would it be too difficult to run the task in another room?

No. Move your computer farther away from you.

I know... I'm just too lazy to move my whole set-up (MBA+power brick+external HDD).

And I do wish to know if there's any way to process something slower if I got the time. (computer staying on overnight anyway)

If you really decide you need to do something like this, see here:

There's a link to a program called cputhrottle that should do what you want. It can set a maximum CPU share to a PID (as opposed, I think, to using nice, which will downgrade the app's priority, but will not stop it from using CPU time if no one else wants it).

Well, I have not done any research but I would not be surprised if you could change Handbrake's priority (nice) or even force a transcoding frame rate limit. Survey says you will do it via the command line or passing some parameters in.

Thanks, I will look into that.

You guys are quick! thanks for the inputs and keep them coming!
