RipBot and Time Taken To Convert

[FSGDAG]

Hello All...

This is my first post but I've been lurking and reading on this site for a while now. Kudos to all the contributors!! You guys have made it possible for a noob like me to be able to accomplish 99% of my tasks without having to ask a ton of questions. Thanks for that.....

My question is about RipBot and the amount of time it should take for it to encode a single ripped Blu-Ray movie. Currently its taking me anywhere between 4.5 hrs and 7.5 hours, depending on the length of the Blu-Ray movie. During the process, my CPU Usage is pinged at 100% the entire time. I'm only using about 2.5 GB of my available RAM during the process though. I'll describe what I'm using and how I'm doing it so maybe it might give a clue as to why its taking so long ( unless that amount of time is normal ).

First my hardware:

Processor = AMD Phenom II X4 810 Quad 2.6Ghz
RAM = 8 Gigs of RAM
O/S = Windows 7 x64 Bit Retail ( was happening on Vista x64 as well )
HDD = SATA 500GB ( O/S ) - 2x SATA 1TB each ( Movies / Music / etc )
Rom Drive = LG Blu-Ray Internal SATA Drive

Software

Latest version of AnyDVD HD - Full Paid Version
RipBot264 1.14.5 ( latest ) + latest version of all pre-req for RipBot264


I start by having AnyDVD rip the Blu-Ray directly to my HDD ( it goes to the O/S drive with 500GB ). It takes AnyDVD roughly 30-45 minutes per Blu-Ray to complete. After its done, I run RipBot264 and take the largest .m2ts file and convert it to a .mkv file. The MKV file is also set to be stored on the 500GB O/S drive.

I'm not really sure if my issue is with my hardware or maybe the settings I'm using in RipBot. But any help is GREATLY appreciated!

I think your encode times are fairly normal for blueray encodeing using a quad-core CPU. The only way to speed it up would be a faster CPU. You might consider upgrading to an x4-940and overclock it to 3.6Ghz. Dual-core CPU's take 14-20 hours.

Thanks for the reply wulf109. I appreciate it!!

Would you happen to know, roughly ( wouldn't expect exact times ), how much time it might take off if I upgraded to the X4 940?? I'm just wondering if worth putting out the money for it, depending on the amount of time I'm going to save

I would agree entirely with wulf109. My quad 3.4Ghz takes about 5 - 6 hours for a two pass BD>MKV conversion. But the quality is great. You can probably OC your CPU up a little and gain some speed. I haven't tried W7 64 bit, but it should be generally faster than my W7 32 bit system at equal clock speeds.

You want to see 100% CPU during H.264 conversions. But you might want to monitor your CPU temps to make sure your system is performing properly. At 100% CPU your CPU can get very warm if you don't have good cooling, especially with long encodes.

EDIT: Faster CPU speeds equal faster conversion times. How much faster depends on the CPU speed. If you can get a 500Mhz - 1Ghz increase, you may see a fair improvement. But it depends a lot on the file you convert. BDs vary quite a bit on conversion speed. RAM or HDD speed doesn't have much effect on conversion speed. But converting to a different drive than your decrypted BD file is on will help. Not using your boot drive in the process usually helps also as the boot drive is used by the OS quite a bit.

If you can OC that CPU you own at present to 3Ghz, should be a fair speed increase.

And welcome to our forums.

If you want faster speed just buy Core i7! Encoding will be about 40% faster than on your cpu at the same clock speed You can speed up whole process by using Single Pass (CQ mode) instead of 2-pass. Just leave CRF@22.

[FSGDAG]

Actually... I am doing CQ. So what your saying is that 2-pass should take that long and CQ should be shorter???

I wasn't under the impression that an i7 was that much faster than a Phenom II X4 series. I thought that was AMD's comparable model to the i7's?!?!?

The i7 are faster than the phenom ll but cost a bit to buy.The phenom ll 940 is comparable to an intel q9450.

I haven't used CQ as I need a set output size from the two pass encode. The first pass usually takes about an hour or so, the second pass about four hours. I would assume the four hour time would be about the same as the single CQ pass if the other settings stayed the same. The i7/i5 CPUs use a bit more efficient data handling system that does speed up encodes, but they cost a whole lot more than the AMDs or the earlier Intel CPUs in part because they use different RAM and more expensive motherboards. I can afford to wait a hour or two extra.

I have a AMD quad and a Intel quad and at the same CPU speed, they take the same amount of time to encode. But I don't have a i7/i5.

I have an i7 920 clocked at 3.8 with a noctua air cooler. Win7 64 bit 12gb ram, and I can convert blu-ray in cq 22 1080p mkv in about 3 hours. If I OC to 4.0, my system overheats and crashes when converting.
At 3.8 my cpu gets to about 74c, and cores also in mid 70s accourding to CPUID hardware monitor.
The i7 is very good and converting video/audio, I had a phenom II previously and this is almost twice as fast using ripbot.
