Converting a Bluray takes unusual long

[Caotica]

Hello guys!

I am new here and, well, came here with a question :-).
Recently, I started ripping all my DVDs and blurays, using Handbrake. DVDs were good so far.
But when I wanted to rip a Bluray (Doctor Who Season 5), Handbrake showed an estimated time between 9 and 12 hours for one episode. My settings were:
CRF: 20
Speed: Slow
Tune: Film.
My target format is H.264. My computer (notebook) has an I7-Quadcore with 2.00 ghz.
Can it really take that long to convert an episode with a runtime of 42 minutes?

Thanks in advance

Seems a little slow. I just tested and I'm seeing 2.9FPS while running two other encodes on a 4GHz Haswell i5. (35-45% util on that encode). So unless it's 50p that should be around 6 hours an episode.
Download HWMonitor and see what your temps and frequency are while running.

Thanks for your answer.
My temperature is between 60 and 62 degrees Celsious (141 and 143 degrees Fahrenheit). I should probably add, that I am blind. So it could be, that my screenreader doesn't recognize it propperly. Can you please tell me, where in HWmonitor's treeview I can find the frequency?
Also, do you think, a processor like, for example the I7-7700K quadcore would bring a significant improvement? I was hoping to get an episode with a duration of 42 minutes done in a time of around 2 hours...

Was that with Handbrake churning away? That seems suspiciously low for a laptop under load, or suspiciously high for one at idle. It would normally be in the 85C range. Perhaps you were reading your motherboard temperature. HWMonitor reads more than one temp.
CPU temp would be under your CPU tab, which should be labeled something like Intel Core i7 2630QM. Core frequency is under there too.

If you want to install Teamviewer and PM me your ID and password I can remote in and take a look.

Yes, that would do it.

Caotica, check your energy plan, you should not allow your hard drive to go into energy saving plan.

@kuchikirukia:
Thanks for the offer. I actually had the chance to have someone look over it yesterday. It turned out, that I read the temperature correctly, and that the temperature is already in the range of 50 when the computer is just idling. Through Google I found out, that this apparently happens, if the fan is just not very efficient. That is probably the reason, why it's barely audible. Not even when I am encoding something.
The frequency while I am encoding is between 2095 and 2295.
But I think, I will just get a new computer anyway. I would like to shorten the encoding time to at least two hours, maybe even shorter, if that's possible, depending on what kind of processor that would take.

@GMJCZP
I switched off any energy saving options, but it didn't really make a difference.

Idle temps on laptops are normally pretty warm since the that doesn't hurt the electronics any. It's a waste of power and noise to try to cool it further. If you're getting 65C load your cooling is excellent.

But your speed seems low for any actual quad-core. Are you sure you don't have a hyperthreaded dual-core? The majority of laptop i7's are actually dual cores.

[Caotica]

@kuchikirukia
You are right. It is an actual dual core. I was confused because of the word "hyperthreaded" and especially, because in the specs from the place, where I bought this laptop, it said, that it was a quadcore. Well, the goodd thing is, that I learned some things the last few days. And I will definitely choose the parts for my next computer myself. Since this is only a dual core, it's no wonder, that Blurays take so long.
Do you have any recommendations for a computer for converting? Anything, that I should pay special atension to? I know, that I need a fast CPU and probably lots of RAM. The plan was also, to put an SSD in there. Is there anything else, I should considder?

[kuchikirukia]

You don't need a SSD at all with Handbrake. Nothing it does it storage speed limited. If you were using Avisynth then a SSD scratch disk would be nice for demuxing, indexing, and muxing, but Handbrake doesn't need to index and it muxes on the fly.
You also don't need much RAM. A 1080p encode with max settings only takes around 2GB itself. No new machine is going to come with less than 8GB and that would be fine, though 16 is a little more future-proof.

But AMD is releasing a new processor series soon. You might want to wait to buy until then, since it may be enough to shake things up. Intel is already coming out with hyperthreaded Pentiums and overclockable i3's in advance of AMD's Ryzen. It looks like they might be adding a hyperthreaded quad to the i5 line too. (so it'll be an i7 with just a little less cache.) We very well may see a hex-core i7 on the consumer platform soon.

I would say the price per GB is cheaper than the price per kWh - do the conversion while the winter is still on, you can benefit twice therefrom.
