Attached a log, it includes attempting to go from 60 to 75 in the first instance. In the second display is at 75 and madvr switches to 60. 50hz works fine so I'm not really missing switching to 75.

According to the log, the decoder seems to claim that the source file is 50p. That's the key problem. If it were 25p or 50i, madVR should switch to 75Hz.

Makes sense but why is madvr detecting it as 50p? Attached a snippet of the video that was used in the log. It happens with all 25p videos I've tried.

Also thanks for fixing the other issues I had in the latest build. On the issue about dropping frames when switching displays of different refresh rates, it no longer drops which is good but madvr osd reports composition of the first display. Should it be reporting the current displays composition rate like it does with display rate?

> Makes sense but why is madvr detecting it as 50p?

That's not what happens. madVR does not "detect" anything. It's the upstream DirectShow filters which report 50p to madVR.

What does the madVR OSD (Ctrl+J) report for you when playing that 25.mkv? It says "movie 25.000 fps (says source filter)" on my PC. There must be something specific to your DirectShow filter chain which results in 50.000 fps being reported to madVR. Maybe your splitter or decoder is responsible for the error. Or maybe you've LAV Video Decoder configured to deinterlace internally? If so, the output will be 50fps and that would be your fault then... ;-)

It does! The problem is that the OS is using a composition rate which doesn't match the refresh rate. That's a problem with the OS, not with madVR.

1. It says 25 fps, uploaded image of the OSD, maybe there's something else there. Nevermind the dropped frames or 50hz display.

2. But in the situation of switching single displays the composition rate does change while madvr osd doesn't in the current instance. Opening another instance of madvr reports it, it's just a very minor cosmetic issue. Not sure if I reported it here or not but is there a way to get multiple displays of different refresh rates to not drop frames in window mode on non-primary/extended display where the composition really is different from display? EVR doesn't handle this correctly either but overlay mixer and madvr's overlay and FSE do.

And in that situation where the ODS reports 25fps, madVR still doesn't switch to 75Hz? Are you sure that this is the very same thing as your log file recorded? Because (unless I've made a mistake when interpreting it) your log file seems to indicate that the OSD should have reported 50fps.

About the composition rate: That doesn't belong into this bug entry. Please reopen the other bug entry and let's continue that discussion there.

It's the full video of what 25.mkv attached is from log and osd are from the full video which switches to 60 instead of 75hz.

How do I reopen a bug entry? Only seeing 13 issues, all either assigned or feedback. None of the resolved/closed issues show.

Ok, the situation is quite complicated but I think I figured it out now. There are 2 basic problems:

(1) It seems that your filter chain tells madVR that the source is 50p. However, madVR has a built in logic which can detect such incorrect information and auto-corrects it. This feature seems to have done its job because according to the log, madVR does handle the source as being 25p or 50i.

(2) I think you have deinterlacing set to "automatically activate when needed" and you have *not* forced film mode. Correct? With this deinterlacing setting madVR cannot be sure whether your video file might not need deinterlacing sooner or later. As a result madVR looks for a multiply of 50Hz, just to be safe. In my case madVR looks for a multiply of 25Hz because I have forced film mode.

I don't think this is a bug in madVR. If I looked for a 25Hz multiply with your settings, madVR would actually switch to a e.g. 1080p25 instead of 1080p50 for some all users with similar settings, even for content which actually needs deinterlacing. So I cannot really change this. It would break things for other users. You can solve the problem by forcing madVR into film mode. Or by adding a 1080p50 mode to the list of supported refresh rates.

You can view closed issues by clicking on "View Issues". Then modify the "Hide Status" and finally click on "Apply Filter".

I am encountering the exact same issue as the original poster, 23.97, 24fps and 30 fps material plays well, but 25 fps becomes 59.94 (the lowest frame rate mode available). I have tried enabling and disabling deinterlacing.

(I will attach a log where I am deinterlacing in the decoder to film mode 25fps and forcing film mode in madvr)
