I'm running 13.1 now on HD6570. MadVR with MPC-HC and jRiver MC18 is flawless on film SD and HD (bluray rips) material (jinc3/AR for both Chroma/Luma). Running a chessy old Athlon II...10bit x264-encoded sources....Encoding video with x264 at the same time as playback....
Anyway, are any of your madVR queues starved? Try going into REclock advanced and "Clean up Video Timings Database", then start a video and let it get it's groove back on, see what happens. Last edited by noee; 18th January 2013 at 02:00. |

If a channel switches from 1080/25p too 1080/25i, if using dxva deinterlacing, shouldn't it detect it needs to go from "no deinterlacing, or "weave" as you describe from the progressive source. Too "vector" for the interlaced source? Because in my case it doesn't. It always thinks the video is progressive, even when I change the deinterlacing in the AMD control panel to vector or motion, there is no deinterlacing, or just "weave" deinterlacing for the 1080/25i video. So since this just happens with Madvr, is this a communication problem between the renderer and the amd driver? Why doesn't it work to set the deinterlacing to vector manually when this occurs? Why does it work forcing deinterlacing on in Madvr? If it could detect the change, should it be sending the information to change the deinterlacing type too the driver? |

Two questions:
1) Is it better to use SVP in conjunction with madVR or does it not make a difference? 2) If I were to use SVP with madVR does the need for ReClock still arise or does SVP eliminate the problem which ReClock is trying to solve as well? |

I tried SVP but could not stand the look of it... It made everything nice and crisp, but it looked cheap and sterile and looked like a soap opera. Not my cup of tea, but some people love it.

2) Reclock is still needed unless you have perfect timing. Please visit SVP forum. The authors are nice guys and the result SVP is able to give in my case are FAR BETTER than the frame interpolation of my TV set.

I'm not sure about that. First of all: See my reply after the next quote. Furthermore: Your screenshot of the Cheese Slice test pattern does not show how proper motion adaptive deinterlacing with diagonal filtering looks like. Proper motion adaptive deinterlacing looks *much* better than that! You're putting way too much stock into the Cheese Slice tests. Furthermore, AMD's and NVidia's implementation of motion adaptive deinterlacing seems to be far from optimal, as far as I can see...
Quote:
Edit: Btw, you can now use the 1080i50 Cheese Slice test patterns to check whether your GPU IVTC algorithm can handle PAL film content well... Compare it to madVR film mode. Use frame stepping and compare pixel by pixel. Or use the 1080i60 pattern to check how well your GPU IVTC can handle 2:2 cadences in 60i content. FWIW, madVR takes too long to switch to the correct cadence here. That's something I'll work on in the future. Edit2: Disable the option "only look at pixels in the frame center" in the madVR settings, and madVR film mode will play all 1080i Cheese Slice test patterns with identical quality to the original progressive source, which is much better than anything AMD and NVidia seem to be able to do.

Some suggestions: (1) Try with software decoding (just in case you have DXVA decoding enabled). (2) Try without Reclock. (3) If you still have problems, make a screenshot of the OSD in the situation when the problem occurs. If we're talking about FSE mode, then maybe PrintScreen won't work? (Not sure). In that case write down numbers of all the queues in the moment when the problem occurs. Then we may be able to identify where the bottleneck is. (4) The madVR OSD probably does report frame drops when the problem occurs? (5) Are you playing progressive files or interlaced files? Try progressive files (e.g. Blu-Ray), because they're easier to play. Does the problem only occur with interlaced files, or with progressive files, too? Not at all. Nobody said it would... Film vs video has nothing to do with your problem. Last edited by madshi; 18th January 2013 at 11:25. |

With this enabled, my MBAFF videos recorded from DVB-T2 correctly switch between progressive and interlaced. Quote:
I know what crappy deinterlacing ("288p") looks like - for example, the UK Coupling DVDs all exhibit this (576p/25 made from 576i/25 but they've clearly just taken every other field and line doubled them). I do not see this with "progressive video in an interlaced stream" material on any of my PCs or TVs. Quote:
Presumably the best way to do this would be to create a 1080p/50 video, then cut away half of each frame to get a 1080i/25 video, then compare the two with different algorithms. EDIT: Hmm, for some reason forcing film or video mode doesn't do anything on my laptop (HD4000). EDIT 2: Oh OK, forcing film mode only works for software decoding.

Last time it happened I noticed on the madvr osd that the clock deviation was like 20%, which is funny... For a while it seemed the problem was fixed then it came back again. |

Speaking of SVP is it only possible to use it with ffdshow software filter? Since it runs on the cpu and without HW accel the decoding also my cpu is far from sufficient and the video card's acceleration capabilities are wasted. Last edited by mzso; 18th January 2013 at 15:10. |

The only time I get dodgy playback in MediaPortal (EVR) is when the GPU and/or driver craps out. This happens rarely but inexplicably. Basically I just get frame drops all over the place for no apparent reason and I have to restart the PC. The other day it was only happening during certain scenes on certain channels - e.g. the adverts would all be fine, but the programme would be crappy (despite everything being interlaced) and another channel would be fine. Oh, the joys of video playback.

@DragonQ, a year ago the NVidia drivers had serious bugs when using madVR fullscreen exclusive mode. These bugs have been fixed in the meanwhile (at least when using win7 or win8 x64). For windowed mode you can now also use Overlay in madVR which could also potentially help avoiding frame drops.

1 frame repeat every 29.94 seconds dropped frames 11 delayed frames 3 all queues are full, i guess its the vsync causing the frame drops? |

It runs under Avisynth so ffdshow raw video filter is needed. It runs on CPU+GPU (Open CL) or CPU only.

So if I want to use YADIF2 deinterlacing in lav for standard def dvb channels, is there anyway to use lav without it applying yadif to hd channels also? At the moment the only solution I have is to uncheck lav to use h264, but then I have to use cyberlink decoder for 1080i instead and id like to use lav instead. |

(1) i always try with software decoding, tried with lav and coreavc, coreavc is much more smooth (2) yes, guess what, madvr started being smooth after disabling reclock. sound is bad now, but i went to the loft and brought my old pci xfi xtrememusic and sound is good again, no need for reclock (3) I will put here my osd after playing a progressive video, with everything you said to disable, now with locked clocks and with ati brand new drivers 13.1 Thanks Last edited by xabregas; 18th January 2013 at 16:37. |

Problem is i think this gpu is very fast, the PQ is amazing with jinc and lanczo with AR enabled, but there is too many things screwing madvr in CCC amazing settings |
