Ripbot Encode Time

[Rustsatz]

I am getting 11-13 hour encode times on all my Blu-Ray movie encodes. I have searched and reviewed many of the topics in this forum relating to Ripbot. It seems as if I should be getting closer to 5-6 hours with my setup;

Q9550 @ 2.83Ghz
6 Gb ram
XP Pro x64 SP2

I encode from a ripped Blu-Ray movie (DVDFab/AnyDVD) that is on another physical disk than my OS. My usual settings in Ripbot are as follows;

Level 4.0 HD, Blu-Ray, Console Profile
2-Pass/Turbo first pass
Auto Crop
5.1 AAC-LC Audio
English language only
Output file size locked at 4480
Saved as .mp4 to the OS hard drive

The ultimate destination for these files are a PS3. I transfer them via PS3 Media Server (wired) to avoid the 4Gb file limit on the PS3 FAT32 drive.

Any suggestions on how I can achieve 5-6 hour encode times would be GREATLY appreciated. Thanks for your time!

Get a faster PC, seriously. I have 2 PCs. One has:
Intel Q6600
4GB DDR3
Windows 7 32bit
And it encode movies in 6-8. I'll be testing that today since you mentioned it to make sure I'm not giving you false numbers. But my other PC on the other hand:
i7 950 OCed 3.66GHZ
12GB DDR3
Windos 7 64bit
Rocks BD in about 2-4 hours. I don't use 2 pass encoding, I use CQ and set it to 22 or 24. Anyway you might wanna check your tech or try CQ setting. Youi know what? I just thought about something. I encode all my movies to MKV. I wonder if that makes a difference?

[Rustsatz]

Thanks, Bwizzy! Other threads in this forum indicate I should be able to achieve a 5-6 hour encode with my Q9550. I can certainly try the .mkv option.

[Bwizzy]

Does the PS3 Media Server play MKVs, I'm unfamiliar with it?

[Bwizzy]

Alright, here are my results:
Doing a CQ cut of a BD I get 7 hours on the Q6600 PC. and on the i7 950 I get between 3-4 hours. Just a side note, my Q6600 has 3 1TB HDD in RAID 0 and the i7 950 PC has 4 SSDs in RAID 0.

It takes me between 6 - 8 hours for a BD>MKV encode, target size 8150MB, MKV, two pass, 6CH AC3 audio, using a 3.4Ghz quad core CPU. RipBot generates a log you can check for encoding time.

Hard drive speed and RAM amount doesn't have much affect on encoding speed. It's almost wholly dependent on CPU speed and the number of CPU cores. I have my Q9550 OC'd to 3.4Ghz and it runs at 100% CPU during the encodes. 64bit OSs can do these encodes a bit faster, but they aren't compatible with some of the software I use.

10 hour 30 minute Night at the Museum 2 encode
13 hour 33 minute Angels and Demons
10 hour 17 minute Miracle on 34th Street

This was a batch job that saved only the first encode (Night at the Museum 2). The other two 'failed to write'. Any ideas?

Have you tried encoding with BD Rebuilder. It's noticeably faster than Ripbot. Have you tried overclocking your Q9550,3.2-3.5 should be possible. My i7 does a typical movie in 4 hours at 3.7Ghz,my AMD x4-620 takes about 6:30 at 3.3Ghz.

[Rustsatz]

Does BD Rebuilder export to .mp4/.mkv?

[Baldrick]

Nope, it exports as a blu-ray/avchd. But you can probably just use the m2ts in the BDMV/STREAM folder with ps3 media server.

I am getting 11-13 hour encode times on all my Blu-Ray movie encodes. I have searched and reviewed many of the topics in this forum relating to Ripbot. It seems as if I should be getting closer to 5-6 hours with my setup;

x264 encoding times are determined by the quality options/presets you select. Choose a faster preset in RipBot.

MKV has nothing to do with it. Using another application doesn't directly matter either. The encoder under the hood (x264) is the same anyway, unless the version is outdated, or if the application doesn't give you a choice of presets (in which case it's a crappy app).

[wulf109]

BDRebuilder does have several options. Higher quality is the default speed,but it has two faster modes,better and good. Good is about 50% of higher and better is about 75% of higher. There's also HighSpeed BD25 mode which only works for BD25 disks and about 50% of the higher speed.
If you don't overclock an AMD quad might be a better choice than Intel. The AMD quads work very well with BDRebuilder.

[Rustsatz]

How much can I expect to overclock on original/stock cooling?

[wulf109]

Intel's stock cooler's are very poor for overclocking. You should download and install Speedfan so you can monitor your CPU temps. You might be able to overclock to 3.2Ghz on the stock cooler but watch your CPU temps.

[Rustsatz]

Do you feel that my encode times are reasonable considering the settings and my hardware? I will give BDRebuilder a try as well.

[wulf109]

I setup my AMD X4-620 to run at 2.83GHz,like your Q9550. It took 7:43 to compress a 2 hour movie,The Brothers Grimm,to a 4480 MP4 file. Your 11-12 hour encode times do seem excessive. I would look at your hard drive,how much free space do you have. It took 18Gbs of space to compress the two hour movie because in addition to the 4.37Gbs for the mp4 file it also created 13.7Gbs in the C:\temp directory. You should manually delete the Ripbot sub-directory in your C:\temp. You should defragment your hard drive that could be the cause of your 11-12 hour encodes. XP has a good defrag utility.

Took me about 70 min to create a 4.37 avchd 720p from land of the lost blu-ray disc with dvdfab 6.BDRebuilder crashed halfway thru with a tsmuxer error.

[wulf109]

But 720P is not BlueRay resolution,that would be 1080P.

DVD Fab - Land of the Lost - 720P - 4480MB

X4-620 @ 3.25Ghz - 76 min.
i7-920 @ 3.70Ghz - 53 min.

[johns0]

720p is blu-ray resolution,just cause 1080p is used for commercial movies doesn't mean 720p isnt blu-ray,just a lower res of it and the time was actually 58 min the second time encoding not doing other stuff at the same time and at 3ghz non overclocked.

[Rustsatz]

Thanks for the Speedfan suggestion, wulf109! I have heat and/or ventilation issues. I was at 95-100C during encode (full CPU load). I assume that has been the case since I installed the Q9550 in November. I hope I haven't damaged my CPU.

[wulf109]

Plenty of good coolers in the $20-30 range. You should buy some Arctic Silver CPU grease,really helps lower temps. A rear exhaust fan also important. I run my i7 with the side panel off the case.

[Rustsatz]

Thanks a million, wulf109. I replaced the stock q9550 heatsink with a E6400 heatsink that I had laying around (it was bigger). Although that in itself will help, I concluded that I had too much thermal paste. I followed the install directions as per Intel and now my full load temps have gone from the upper 90s to the upper 60s. I have yet to run another session with Ripbot but I can only assume it will be quicker. One more thing, will a RAID 0 setup improve encode times?

Thanks again wulf109!

[redwudz]

RAID 0 won't have any real effect on encode time, it's almost completely CPU dependant. When using a codec like X.264, high CPU speeds and multiple CPU cores help the most. RAID 0 is also not fault tolerant, so if one drive fails, you loose all data on both drives.

[Rustsatz]

Problem solved. After 'reseating' my heatsink with the proper amount of thermal paste, my encode times are much more tolerable. I am getting anywhere from 5-8 hours now. Thanks again to wulf109 for pointing this out. And thanks to everyone else for their time and suggestions!

[Peakr]

Most likely your cpu was down clocking itself for protection against the heat, causing the long encode times. A good heatsink will help you with a higher overclock. Check your cpu stepping with CPU-Z. Most q9550's G0's will overclock to 3.6-3.8 with stock voltage as long as your ram's decent. A 64bit OS will help with times as well. 64bit x264 is worth an extra 10% in speed.

[johns0]

With a really good hsf your temps should only get to the high 40's,high 60's it running too hot,high 90's was cooking bacon.
