Blu-ray Ripper with CUDA acceleration: how fast could it be?

Movie enthusiasts, you gotta try Pavtube Blu-ray Ripper v3.7 if you wanna accelerate the conversion speed when backing up BD collections to PC. The software now lets you take advantages of GPU acceleration and rips Blu-ray and DVD faster than ever! News taken from the Pavtube official site--- “Dec. 2, 2010 - Pavtube Blu-Ray Ripper now takes full advantage of the latest NVIDIA CUDA technology to speed up Blu-ray ripping process. Now with a CUDA-enabled graphics card, the BD ripping speed is accelerated up to 3X faster than before, which saves you lots of time to wait around.”  

I was so excited with the news that I performed a Blu-ray ripping process with CUDA vs. without CUDA test on my PC last night. Pavtube Studio claims 3X faster speed and 96min for ripping Avatar Blu-ray to 1080p MP4 on 4 cores PC with CUDA support (check for details here), well I do not own a fast PC and it took much longer to rip Inception BD… Anyway, the results revealed that it is actually 2.7 times faster when CUDA is enabled! Here’re more details:

Test environment

  1. Processor: Intel(R) Pentium (R) Dual CPU E2140 @1.60GHz
  2. Memory: 1022MB RAM
  3. Drive: External Sony BD drive with USB 2.0 USB cable
  4. Graphics Card: NVIDIA GeForce GTX 460, latest NVIDIA CUDA drivers installed
  5. Operation System: Microsoft Windows XP Professional

Test tools and method

  1. Source Media: Blu-ray Disc Inception
  2. Software Tool: Pavtube Blu-ray Ripper v3.7.1.2290 trial version.

Test procedures
Step 1. Connect the external BD drive to PC, place in source Blu-ray Disc Inception. Ensure the desktop is networked. Install and launch the Pavtube Blu-ray Ripper v3.7 software (trial), click the BD icon to load Blu-ray Inception from BD drive.
Step 2. Select the main movie, click on the dropdown list of "Format", follow “HD Video” and select “MKV HD Video (*.mkv)” as output format. Click “Browse” to set a folder for saving converted H.264 MKV files.
Step 3. Click "Convert" button to start ripping Inception to hard drive, and take down the test data when conversion completes.
Step 4. Click “CUDA” icon to turn off GPU acceleration, and repeats Step 1 to Step 4.

Test results
It takes 16hrs (968mins) for ripping Inception Blu-ray to 1080p H.264 MKV with CUDA off comparing 6hrs (362mins) with CUDA on. Both of the conversions generate MKV file of 9.64GB. And both the file plays great in VLC Media Player. To conclude, the Blu-ray ripping speed is 2.67 times faster with CUDA enabled. I’ll call it an acceptable result for such a slow desktop. Hopefully the Pavtube Blu-ray Ripper can do better in future. Anyway, wish you luck with the implementation.

What is CUDA?
bluray ripperCUDA™ is a revolutionary parallel computing architecture from NVIDIA that enables dramatic increases in computing performance by harnessing the power of the GPU (graphics processing unit). With millions of CUDA-enabled GPUs sold to date, software developers, scientists and researchers are finding broad-ranging uses for CUDA, including image and video processing, computational biology and chemistry, ray tracing, and much more.

Blu-ray ripping: why it takes so long?
By ripping Blu-ray to 1080p HD video clips, the Blu-ray movies can be played back freely over PC HD media players and Video DVD players as well, and are no longer restricted to play in applicable Blu-ray player only. Many movie lovers find it takes long time to rip a Blu-ray Disc to PC, especially when they choose 1080p MKV/MP4/AVI/WMV as export format. If you have a PC/laptop with Intel CORE i5/i7 processor with 6GB of RAM or above and run an effective Blu-ray ripping/converting tool exclusively, the Blu-ray ripping process could takes around an hour. Generally speaking, Blu-ray ripping process can cost 2-8 hours when working on a regular PC. The higher quality you get, the longer it takes. Learn how to gear up Blu-ray ripping speed with CUDA.
