Test: DVD rip speed with Handbrake and Quick Sync on Ultrabooks

Ultrabook DVD

Backing up DVDs is an important topic for many people. Transferring the DVD to a portable format isn’t easy though and can take a lot of time. My daughter is away this weekend and I thought it would be nice for her to be able to watch some of her DVDs on her PC while she’s away. Her netbook, tablet and smartphone don’t have DVD drives (although the netbook has a DVD playback license) so there’s only one thing possible – transfer them to a portable digital format. I’ve tested three generations of Ultrabook with a very simple DVD backup process and the results are below.

The legalities of DVD backups are very country dependant and I believe that the process below could be illegal in my home country if used to back-up a complete DVD. I’m doing the research, doing the testing and leaving it up to you to decide for yourself what to do. During this test I’ve only run the process partially to measure the performance. I haven’t backed up a complete DVD in this test. Again, copying commercial DVDs for backup or transfer purposes could be illegal in your country. Never share copied commercially protected DVD content.

The tool of choice for decoding and encoding is Handbrake, the well-known, open-source video conversion tool. It doesn’t natively support ripping DVDs (the DeCSS process to be exact) but if you’re interested in ‘Fixing Handbrake’ to achieve that, you won’t need to Google search too far to find out about ‘Fixing Handbrake.’ Got it?

Handbrake beta software now supports Intel Quick Sync.

The set-up I’m using here is based around a Samsung SE208 Slim USB 2.0 DVD Writer. (Review) which should be able to read a commercial DVD at 8x speed. It’s connected to the USB3.0 port on the test Ultrabooks. All the Ultrabooks are running Windows 8 without the Media Center pack. Windows 8 and Windows 8 Pro don’t support DVD playback. The Media Center pack, €9.99, adds the required codec for media playback.

Ultrabooks in this DVD rip test:

  • Ultrabook 1 – 1st Generation (Sandy Bridge Core i5-2557M 1.7-2.7Ghz, HD3000 media engine.) Toshiba Z830.
  • Ultrabook 2 – 2nd Generation (Ivy Bridge i7-3667U 2.0Ghz-3.2Ghz, HD4000 media engine.) Intel Developer Ultrabook.
  • Ultrabook 3  – 3rd Generation (Haswell, i5-4350U 1.4Ghz-2.9Ghz HD5000 media engine.) Intel Developer Ultrabook.

Test DVD: Commercial (CSS encrypted.) Fresh from packaging.

Handbrake software in test: http://sourceforge.net/projects/handbrake/files/Betas/QSV/HandBrake-svn5671_x86_64-Win_GUI.exe/download
(The current Intel Quick-Sync-enabled Beta from this download page)

The Handbrake build has been changed to decrypt CSS as detailed in other web pages. (Search Google for ‘Fixing Handbrake’ and look for links to libdvdcss-2.dll from Videolan.)

Handbrake settings.

  handbrake iqsv settings handbrake settings 2

  • Test 1 settings (left image above) – Default ‘QuickSync’ profile.
  • Test 2 settings  (right image above, without Intel QS) – Default ‘Normal’ profile

The process was left to run for 5 minutes before taking the average FPS reading. 3 minutes ‘cool down’ was left between tests. Ultrabooks were powered by mains with ‘balanced’ energy profile. (Haswell device in use is Connected Standby-capable and therefore has no power profiles.)

 

Handbrake DVD encoding speed results, with and without Intel Quick Sync hardware.

Ultrabook 1

Ultrabook 2
Ivy Bridge, HD4000
107.6 (CPU: 15-23%, No Turbo Boost, No Fan) 107.4 (CPU: 75-100%, Turbo Boost used, Fan active.)
Ultrabook 3
Haswell, HD5000
107.3 (CPU: 12-17%, No Turbo Boost, No Fan) 108.0  (CPU: 55-100%, Turbo Boost used, Fan active.)

Removing the DVD as a bottleneck

Following a suggestion, I took a direct copy of the DVD video and audio TS folders and placed them onto the local SSD of the Haswell Ultrabook. From there I repeated the process.

Ultrabook 3
Haswell, HD5000
338.0 (CPU: 50-60%, Turbo Boost, Fan) 148.4 (CPU: 55-100%, Turbo Boost used, Fan active.)

Clearly the DVD read speed is a bottleneck in the process but the results also show the limit of CPU-based, software codecs and the advantage of using the Intel Quick Sync process, approximately 2X in speed with the Haswell-based Ultrabook and over 3X speed over a software codec on the Sandy Bridge Ultrabook.

Note that the combined time of copying the DVD to the SSD and then running Handbrake is longer than a slower-speed Handbrake-only process. The answer here is to use a faster external DVD.

Important note: I haven’t inspected the results for quality. I’m looking for ‘acceptable’ audio and video from a consumer perspective and I believe that both the Quick Sync and software codecs reach that level of quality. Quality may be an issue for those looking for the highest quality encode.

RipLock, Slow Starts and Queuing

It’s worth mentioning that these tests only include a 5-minute ‘rip’ test. DVD ripping always speeds up as the process progresses as long as the PC can keep up with it. For example, at 40% into the process, I see peak rip rates of 156 FPS and rising. Due to this slow-start effect the DVD-based test results here aren’t showing the true average speed. Also note that Riplock is a ‘feature’ that could limit read speeds of your DVD drive. Damaged disks, incorrect region and other DVD protection features can also slow down the process.

For those doing multiple ‘rips’ it could be better to copy DVDs to ISO’s on a hard drive first and then queue the conversion process in Handbrake to run automatically and unattended. The overall time is longer but the time needed changing discs would be less.

Summary of DVD rip speed results.

The Ultrabook is highly capable of a fast decode/encode process and with Quick Sync enabled in this version of Handbrake it can be much faster, quieter, cooler and more efficient. DVD read speed is the bottleneck in this test setup though.

The Handbrake software encoder often hits a bottleneck with CPU power whereas the Quick-Sync tests show a lot of headroom in the CPU power.

The Haswell Ultrabook running a software encoder was the fastest Handbrake-only (direct from DVD) result by a very small margin although the fan noise and CPU utilisation (which affects battery life) must be considered. The only setup that showed limits in the CPU processing was software encoding on the Sandy Bridge Ultrabook.

The disk-based 300+ FPS speeds seen here are impressive and show the real power of a modern Ultrabook using Intel Quick Sync.

Final note: Copying commercial DVDs for backup or transfer purposes could be illegal in your country. Never share copied commercially protected DVD content.
