MadVR AR is not always set to what it should be

[tingtong5]

Hi,

I made a profile rule that checks AR (aspect ratio), when AR > 2.2 then profile1 should be used otherwise profile2.

This works, but only in some cases. In most cases when watching cinemascope (aspect ratio of 2.40) content MadVR reports (using CTRL-J) an aspect ratio of 16:9 (which is 1.78) instead.

What is going on here? Why are some many movies reporting the wrong aspect ratio? Is MadVR to blame here or is this due to the way the movies are encoded ?

a movie on a BD is always encoded as 16/9 so 21/9 has hard coded black boarders.

A ok, I already thought it must have been something like that...

So that leaves the question: howto make a rule in madvr that distinguishes between 16:9 and 21:9 ?

My goal is to have non 21:9 movies automatically stretch vertically because of anamorphic lens setup and 21:9 screen.

madVR has an option to detect and crop black bars, that could help you.

Yep, I know, unfortunaltly it does not support vertical stretch, only zooming...

Well the "AR" profile variable should update when its cropping black bars, so you can use your profile again.

Ahh, that is good news :-) Accept for the fact that an unwanted zoom has then be applied to the video I want to play...

Go to devices -> your device -> screen config and enable "anamorphic lens".
You have to set your device to digital or crt projector to access this option.
Obviously you'll have to use profiles here to automate it.

it can easily work without profiles.

just tell madVR what type of lens you have and madVR will take care of the rest.

I misunderstood. Yesterday I looked into it and its working fine now :-)

I was not aware (my native language is not english) that "crop black bars" actually means deleting them. So I enabled this option and after that my rule is working and the correct profile (with enabled anamorphic lens option) is selected :-)

Thanks all! :-)
