madVR Subtitles in 3D movies
Hendrik:
Re-encoding while swapping the eyes could work, but i'm not aware of any 3D MVC encoders available, as you would need to actually change the video, not just the container. You could encode it into SBS, but thats not really the same experience.
If the primary eye would be wrong for the video, it would entirely be unwatcheable, similar to how the subtitles behave - instead of just having that problem with the subtitles.
Technically LAV Video could swap the eyes after decoding and just always pretend its always left-first, but then we would have to somehow prevent madVR from reading the eye order, so it doesn't get it wrong, its all sorts of messy.

Only container supporting 3D frame pack is MKV which contain flag for which eye is first ... you can change that flag with MKVToolnix (require remuxing) ... you can also override flag value in MadVR (for cases where flag was set wrong and you are too lazy to remux)
But in this case flags are set correct ... MadVR is playing video correct (as Hendrick mention when you play incorrectly ... video is unwatchable) ... MadVR is just doing subtitles and OSD wrong for "right eye first"

Now THAT is good walkaround ... which will set MC apart from others :)
Here are screenshot of what I am talking about:
1. for left eye screenshot ... see how subtitles on top is offset to the right of subtitle on bottom ... this make subtitle "come out of screen"
2. for right eye screenshot ... subtitles on top is offset to the LEFT of subtitle on bottom ... this make subtitle "go in the screen" ... with all other things combine - cannot focus on subtitles
I included a 3rd screenshot of that "right eye screenshot" ... but with text overplayed correctly ... if you have 3D display/projector that support Over/Under ... you can make those screenshot fullscreen, then switch display to 3D Over/Under and you will see what i meant

I dont think MadVR can determine which eye is first ... as it seems to always rely on MKV flag (not sure how it determines from ISO or BDMV folders) and never overides it unless explicitely told to do so (you cannot specify which eye is first in MadVR menu ... you can only choose to swap eyes)
