Fast rip Blu-ray Disc on a slow computer with CUDA implementation
Movie lovers rip Blu-ray movie from BD to HDD for various reasons: to protect original BD from scratches, to copy the BD movies to home server, to compress Blu-ray to iPad for travel or whatever. The biggest problem comes up with Blu-ray ripping must be the BD copy-protection. Long processing time seconds it. Yet there is a fastest way for backing up Blu-ray movie to PC without quality degradation—simply decrypt and copy the BD movie to HDD without transcoding. This takes less than an hour on an average computer. However, most media players prefer common video formats and will not play Blu-ray .m2ts streams properly. That’s why most users create BD backup by converting BD to HD MP4/MKV/AVI/WMV videos. The problem is BD transcoding process is time-consuming. Considering the file size of Blu-ray movie (20GB- 50GB), it is reasonable for a high horsepower computer with Intel CORE i5/i7 processor and 6GB of RAM to complete Blu-ray ripping in 1-2 hours. For an average computer, the ripping time could be 3-9 hours when an effective Blu-ray ripping/converting tool is run exclusively. Suppose it takes 10+ hours to rip a 90min movie to 1080p video, you are encouraged to use a faster computer for faster BD ripping speed instead. Anyway, that’s not the focus of this post. Let’s get down to our point- how to fast rip Blu-ray Disc to H.264 HD video on a slow computer by taking advantage of NVIDIA GPU acceleration. In order to use the CUDA implementation, a NVIDIA CUDA enabled graphics card is required.
The computer info I use for BD ripping:
Processor: Intel(R) Pentium (R) Dual CPU E2140 @1.60GHz
Memory: 1022MB RAM
Drive: External Sony BD drive with USB 2.0 USB cable
Graphics Card: NVIDIA GeForce GTX 460, latest NVIDIA CUDA drivers installed
Operation System: Microsoft Windows XP Professional
Make sure you have basic tools for BD ripping: your desktop or laptop running Windows XP and above OS with NVIDIA CUDA enabled graphics card; an Internal or external Blu-ray Disc drive; source Blu-ray Disc, here I use Alice In Wonderland Blu-ray which is 1 hour and 48 minutes in length; and Pavtube Blu-ray Ripper v3.7.1.2290 trial version.
Step 1. Connect the external BD drive to PC, place in source Blu-ray Disc Alice In Wonderland . 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 Alice In Wonderland from BD drive. Make sure “CUDA” icon is turned on (highlighted) for CUDA implementation (Click the icon to disable/enable CUDA acceleration implementation)
Step 2. Select the main movie, click on the dropdown list of "Format", follow “HD Video” and select “MP4 HD Video (*.mp4)” as output format. Click “Browse” to set a folder for saving converted H.264 MP4 files.
Step 3. Click "Convert" button to start ripping Alice In Wonderland to hard drive, and take down the test data when conversion completes.
See how much CUDA has fasten Blu-ray ripping speed on my slow desktop:
1. Ripping Blu-ray Alice In Wonderland with CUDA ON:
Ripping time- 3 hours and 8 minutes
Generated file size- 7.07GB
2. Ripping Blu-ray Alice In Wonderland with CUDA OFF:
Ripping time- 12 hours and 5 minutes
Generated file size- 7.05GB
By implying CUDA acceleration the Blu-ray ripping speed is 3.87 times faster than that CUDA is disabled.
To properly play M2TS streams back will require both a high horsepower computer and high speed disk drive array to support the data rate involved in that format, while play 1080p H.264 MP4 you just need an average computer like the one I user for ripping Alice In Wonderland to H.264 HD video. Here’s a compressed screenshot of converted Blu-ray movie by Pavtube Blu-ray Ripper v3.7:
The Xbox 360 is not only a game console, but also a media player that allows you watching movies on your HDTV. Being different from Sony’s PlayStation 3, Xbox 360 can not be used as a Blu-ray player, and you have to convert the Blu-ray m2ts streams to Xbox 360 supported format first. WMV HD might be the optimal format for streaming Blu-ray to Xbox 360, but it’s not the only one. The Xbox 360 also supports H.264 and MPEG-4 encoded MP4, MOV, M4V files and DivX AVI video clips. Let me tell you something: if your PC is equipped with an NVIDIA CUDA ready graphics card, then H.264 MP4 is a better export format than WMV, because this format allows you to take advantage of NVIDIA’s GPU acceleration, improving the ripping speed to 3-4 times faster. The following guide focus on how to stream Blu-ray to Xbox 360 with CUDA implementation.
Make sure you have these tools:
PC running Windows XP, Windows Vista, and Windows 7 with a NVIDIA CUDA ready graphics card; an BD drive for reading Blu-ray contents from BD; and Pavtube Blu-ray Ripper software (click to download a trial)
Detailed guide: How to stream Blu-ray movies to Xbox 360 at fastest speed?
Step 1: Run Pavtube Blu-ray to Xbox 360 Converter
load BD files to it,You can click “BD/DVD ROM” or “BD/DVD Folder” to load Blu-ray movie files into the app. When movie is loaded, check if the CUDA button is activated.
Step 2: Select H.264 HD output format for Xbox 360
Click on the drop-down list at the opposite side of “Format”, and then choose “HD Video” > “H.264 HD Video (*.mp4)”. The format generates 1080p HD MP4 video with AAC 5.1 audio for Xbox 360 playback.
Step 3: Start ripping Blu-ray to Xbox 360 supported H.264 HD MP4 at 1080p
Click “Convert” button to rip Blu-ray to Xbox 360, once the ripping task is finished by Pavtube Blu-ray to Xbox 360 Converter, you can click “Open” button at the bottom of the main interface to get the output MP4 files for Xbox 360, and to stream Blu-ray movies to Xbox 360.

The acceleration rate may be different based on the computer you use for BD to Xbox 360 conversion. You can try the Pavtube Blu-ray Ripper software and compare by yourself.
