I have completed a new system build and now have a fully stable Intel 2600k over-clocked to 5.0GHz on the ASUS P8Z68 Deluxe platform. So I have been experimenting with optimal AV codec settings to fully exploit the QuickSync feature available in Intel Z68 Motherboards.
Using a purchased Blu-ray disk of Insidious, I created a full clone .ISO file which resulted in a 26.6 GB file. This ISO file and DVDFab v8.1.2.5 were the basis of all my performance tests....
The AV / Codec settings for Decode were:
H.264 - QuickSync
VC1 - CUDA (I have a mid range Nvidia card (EVGA GTS450)
MPEG2 - QuickSync
The AV / Codec settings for Encoder were:
H.264 - QuickSync
Lightning Recorder was NOT activated / checked.
Using the BluRay "Full Disk" copy to a BD25 target it took a disappointingly long 3 hours and 29 minutes to transcode. This test was with the "HD Audio" set to "Off". As an experiment, I retried the Full Disk copy, but with HD Audio now set to ON. To my great surprise the transcode now only took 46 minutes to complete!
Is this a software bug or are my observations what the developers intended? Naturally I would like to see this performance reversed, since I want to afford more space to the video content and not to audio, but with such a performance delta, I am going to stick with including the HD audio, for now.
I would appreciate other forum members who use QS could confirm this observation.
One final observation..... It seems v8.1.2.5 has improved the QuickSync decoding quality. In previous versions, I observed very poor output quality when ripping a BluRay to a iPod / iPad compatible format. The video would have many artifacts and the playback with stagger. Other members had experienced this and several recommended to use "Software" as the video encode option (which I did). But it seems v8.1.2.5 has improved this tremendously and when using QuickSync for both decode and encode I have seen iPad / iPod rip frame rates as high as 178 frames per second! I too would appreciate any QuickSync forum members who used the encode "software" option to see if v8.1.2.5 has improved their results.
Thanks
