You can't control position of the pgs/dvb subtitles. Unfortunately there is a bug in the ISR and if window size is not exactly the same aspect ratio as video frame subtitles will be wrong positioned. As for text (.srt) subtitles you can change their position in options (options->default style->screen alignment and margins) just increase bottom margin to move subtitles higher Last edited by kasper93; 11th January 2013 at 12:13. |

I thought of that too and that's why I disabled
however it's not very clear to me that, that option is actually disabling it whole nor do I know what exclusive means... perhaps the author will come and shine light upon me on this "issue" |

That said, Fullscreen Exclusive does take a split-second longer to enter Fullscreen than Windowed, which can potentially make this stretching anomaly more obvious. |

Madshi, do you know why this MBAFF AVC video isn't deinterlaced by MadVR in auto mode (using LAV & MPC-HC)? EVR plays it back fine (25 fps during first ~10 s, 50 fps for last ~20 s) but MadVR never turns deinterlacing on.

LAV also thinks this at first, but once it switches to MBAFF, LAV notices and informs madVR with a new media type (switches from interlace flags 0x0 to 0x81), but this is not enough, apparently. You can actually fix this by setting LAV to "Aggressive Deinterlacing", this flags the stream differently and overwrites madVRs bitstream info (this uses interlace flags 0x1)

Thanks for the explanation. Does this require a change in MadVR to fix (rather than workaround) then? Also, would enabling "Aggressive Deinterlacing" have any adverse effects on other files?

Because of many decoders misbehaving and setting interlaced flags wrong, i don't think madshi wanted the behaviour much different (i have discussed this with him before )
Anyway, Aggressive Deinterlacing usually doesn't have any real downsides with hardware deinterlacing, because the HW Deinterlacer can figure out if something needs deinterlacing before doing it, but with YADIF it may degrade quality a bit on mixed content (mixed progressive/interlaced). Pure progressive content is not affected at all by the setting.

Interestingly, although the "Aggressive Deinterlacing" workaround works for the ~hour of interlaced video after the progressive title sequence, it doesn't work for the pre-titles section, which is definitely interlaced video but not being detected as such. Tis possible the metadata is wrong in this section. Sample here.

hey guys, just wondering if I will get frame drops no matter what I do unless i get reclock? I managed to get my display refresh to a 23.976xx something - madVR displays that, but still I get a 1 frame repeat every 12-13 minutes - or so the OSD shows. Unless I configured something in madVR badly? Cheers

I think this would be a right time to make use of IRC for discussions related to madVR since the response time may be quicker for simple questions.
And to keep doom9 updated we can log the channel and maybe madshi could add a link to the log in the first post? |

I still get drops. Madshi suggested it could be due to the clock deviation so your display will never exactly be 23.976. For those brief moments I guess you could drop a frame. That's my understanding I actually made adjustments to my playback rate upwards in tiny increments using svp until I got 0 frame drops but can't really be sure that im not getting frame repeats. I think there's always a need for some software solution to sort out this type of problem I guess. Matching rates is good but not enough. |

for example. I don't use Mediaportal but JRiver MC is now my normal HTPC frontend and they are now aggressively incorporating both the latest MadVR and LAV builds (in fact they somewhat overzeleousy included a LAV beta in a full release a few days ago!). JRiver MC includes Videoclock which has all the benefits of Reclock in a supported package with LAV and MadVR. Last edited by Jong; 12th January 2013 at 21:26. |
