Well, even if you don't have to resize, you still get best in class chroma upsampling, a full 16bit processing queue with all its benefits for image quality and best in class YCbCr -> RGB conversion with included gamut & gamma correction. Finally, due to the way madVR works, all the damaging video processing algorithms which graphics card manufacturers like to use, are disabled.

This does not happen with MPC HC for me. Seems to be a ZoomPlayer specific problem?

Actual processing is done in 32bit floating point (that's the native processing bitdepth of GPU shaders), but temp buffers used for storing processing results can be either 16bit or 10bit, depending on the madVR settings. Final RGB output bitdepth at this time is always dithered down 8bit, but the down dithering is only done in the very last step. I'm planning to add support for 10bit and 16bit output modes once Windows 7 arrives. The 10bit/16bit switch in the madVR settings only applies to the temp buffers.

- JR Media Center

Seemingly: MPC HC (special build), ZoomPlayer and ReClock.

You'll have to ask the JR Media Center and ArcSoft guys about madVR support. Not sure if there's any chance with ArcSoft because they may need to use protected data paths for copy protected material, which madVR doesn't support.

Can you describe that weirdness for me? Is there some visible corruption? Or is the image just squeezed for a short time?

I'm not sure if it can be improved much. Reading a 96MB file does take its time.

That will require a combined effort on my side and MPC-HC side, but it should be possible to do. One problem is that I think the best place for some shaders would be in YCbCr space and madVR could offer that to custom shaders, while VMR/EVR can not. So MPC-HC currently does not support YCbCr shaders.

BTW, forgot to mention: Subtitle rendering is currently not supported. That needs to be added, too.

That's already planned.

madVR getting united with MPC HC is not in the cards, because I want madVR to be media player independent. You know, although personally I'm using MPC HC for now, some people prefer ZoomPlayer.

But as explained in the first few posts of this thread, I'm planning to work on motion smoothness.

--------------------

Can I get some specific feedback, please? I'm especially interested in playback smoothness? Do you guys get stuttering with madVR? Or is your graphics card fast enough? How smooth or non-smooth is motion display for you currently? Especially if you set display refresh rate to 1:1 match with the source frame rate? Are the Beliyaal special builds a lot smoother for you, or only slightly so? Thanks!
