I guess that dependswithwhichCPUorGPU iscomparedQS.


AnywayI also readthat theIntelencoder with QSis faster thanother encoders, but withworse qualitythan the others.
GOM VCis not onmy Lucid list. I've tried adding
MediaCoder andGOM VC executablesin "D" mode (discretecard), but I still can not useQS with my nvidia.
The curious thing in Lucidis thatthe only applicationsthat arelistedby defaultin "I" mode (integrated graphics) are threevideoencoders. It's likeLucidwould only workto try to improvethe performance ofQSwhen the monitoris connected to theintegratedvideo.ButI'mjustassumingthat it is.

Yes, not surprising really seeing as it only uses 1 reference frame. It's pretty basic encoding, a lot like streaming media. Hardly what you want for anything decent. However, seeing as Quick Sync can decode video very quickly, far faster than my GT240 with the VP4 decode engine can do, it could have some use for me when encoding to lower resolutions where the encoding speed it currently faster than my video card can decode it. That is what I wanted QS to do. It would be best if Donald Graft had an application to do the Indexing using QS because that would do it well without any issues that Directshow can introduce. He has said that he was interested in developing for QS but he doesn't have the development hardware ATM. I thought about multiplexing H.264 video into a MKv container with every frame referenced which isn't usually used in order to index the file and help with seeking and proper frame retrieval during encoding. I haven't tested that so far because QS decoding has not worked for me.


Have you ever looked at DGDecodeNV? If your not into AVISynth scripting you might never use it. I think that MeGUI can make use of it. It uses nVidia graphics cards to decode Mpeg2, H.264 and VC-1 video such as that from HDTV and BluRay.


What is the application between Media converter 7 and Media espresso in the Lucid Lugix (LL) application tab? I cannot read the name on my system due to the layout making the name unreadable. From what has been said about QS, I would say that the I mode is required to make use of QS and the onboard graphics connector connected to a monitor.


It might be possible to add new applications, specifying the main encoding executable and marking it with the "I" rather than the "D" in LL applications.
