[Request] Intel Quick Sync support
« on: July 22, 2014, 02:40:58 am »
I think it would be fantastic if Dxtory could take advantage of Intels Quick Sync technology.

Intel Quick Sync Video is Intel's hardware video encoding and decoding technology, which is integrated into some of the Intel CPUs. The name "Quick Sync" refers to the use case of quickly transcoding ("syncing") a video from, for example, a DVD or Blu-ray Disc to a format appropriate to, for example, a smartphone. Quick Sync was introduced with the Sandy Bridge CPU microarchitecture on 9 January 2011.

Quick Sync has been praised for its speed. Eighth Annual MPEG-4 AVC/H.264 Video Codecs Comparison showed that Quick Sync is comparable to x264 superfast preset in terms of speed, compression ratio and quality (SSIM); tests were performed on Core i7 3770 (Ivy Bridge) processor. A benchmark from Tom's Hardware showed that Quick Sync could encode a 449 MB, four minute 1080p file to 1024×768 in 22 seconds. The same encoding using only software took 172 seconds but it is not clear what software encoder was used and how it was configured. The same encoding took 83 or 86 seconds GPU-assisted, using a Nvidia GeForce GTX 570 and a AMD Radeon HD 6870 respectively, both of which are contemporary high end GPUs. Unlike video encoding on a general-purpose GPU, Quick Sync is a dedicated hardware core on the processor die. This allows for faster and more power efficient video processing.

If somehow we had a quicksync enabled vfw codec then someone could implement it easily.

This is an old post. But I totally agree with it. The only downside to Dxtory right now, is the file size. Other than that it is the best recorder out there. If you added Quicksync to allow us to use the Intel onboard H.264 encoder (I believe AMD has an equivalent now, too), then Dxtory would hands down be the ONLY choice for professional screen capture.

Would love to see this feature added!

This technology sounds awesome! Dxtory captures are really too big and need some more compression. Maybe the new H.265 Codec could help?
