madVR wiki thread
flac.rules:
I am sorry if my question are stupid, my knowlengde in this field is limited. But madVR is a renderer (i assume the renderer is the program drawing the picture on the screen), that has additional functionality that the decoder usually does (ffdshow in my case), like resizing? And the powerstrip part, is it needed for me? I have a ati 5750, and it supports 23.97, do i need to mess around any more with power-strip, timings and so on?

I also want to thank you for making the best video renderer ever! I didn't know about madvr until JimH mentioned it in a post and now that i'm using it, i can't believe how i was "stuck" with EVR and other renderers in the past.

Glad you like it! :)

Correct. Although it is not usually the duty of the decoder to resize. ffdshow doing that is rather unusual. Most decoders do just decode and nothing else. The video renderer is the best place to do resizing. madVR resizes in higher bitdepth and quality than ffdshow. E.g. ffdshow resizes in 8bit integer per channel, while madVR resizes in 32bit floating point per channel.

If you can run a full movie through without any frame drops/repeats then you don't need to mess around with PowerStrip etc. It depends on how well ATI's default 23.976 mode works on your PC. With a bit of luck it's already near enough perfection that manual tweaking isn't necessary. Furthermore, if you enable MC's new "VideoClock" feature, you won't have to mess around, anyway, because "VideoClock" makes sure that no frame drops/repeats will occur. It comes with a small cost, though: Audio quality might suffer a tiny little bit because VideoClock resamples audio.

Thanks for good information. Is there a program or utility that can measure if i get drops or repaets? Or can i do it via MC? So i know if need to engage the videoclock-function?
madshi:
The madVR OSD (press Ctrl + J) counts frame drops. It doesn't count frame repeats currently, though. That will come in a future version. You can ignore frame drops that happen during the first 5 seconds of playback. There will probably be a few. After a couple of seconds playback you should have no further frame drops, though, if the GPU refresh rate perfectly matches the audio hardware clock.
jmone:
Let me add my thanks to Madshi and Matt. It was a pleasure to see them work together and help push MC's Videophile credentials.
On a well setup system with a correctly calibrated TV the results are just 1st rate. The other feature recently added that should not be overlooked is MC's ability to resample audio so that video frames are not dropped/added (eg reclock like) though I'm still stuck with reclock till an auto frame rate change feature is added to either madVR or naively in MC.
Thanks again,
Nathan
