Two video files?

#1 Post by Smiggy » Fri Dec 30, 2022 12:07 am

Hi,

I've ripped this Blu-ray movie, Journey to The Centre of the Earth, but when I open it in makemkv, there seems to the option to remove the video file, normally this isn't the case and for this movie, there are two video files.

Why is this?

Did I rip it incorrectly?

Your image shows ONE file, which you've removed the video portion from. Is that what you want?

I don't understand what you mean.

Most of my rips look like this with no option to select.

Looking at the two images, one is from disk 1, the other from disk 2. Disk 1 has an optional video track that's been excluded. I would guess it's for a stereo picture.

I have rarely seen this option, because I don't do 3D. This is probably the secondary video channel needed for splitting the picture into stereo. The last 3D movie I bought as a test is in storage right now, but the 3D disk was separate from the 2D disk, and I remember the stereo video channel was marked as "MVC".

It took me some eye-pinching to scan the screenshots. I think Woodstock is right with reading the additional MVC track.

FYI a 3D-BD carries two videostreams. The main AVC stream is the largest and holds independent (2D) video. Secondly there's a smaller, dependent MVC stream. This one contains differential videodata. With which - combined with the data in the 2D stream - a 3D capable player creates the videostream targeted to the other eye. So, for muxing a 3D mkv it is required to select MVC.
Not selecting it will result in "2D-only" video. Which saves space.

Out of Topic: Right click the image and open it in a new tab, then you can see it in original size.

Didn't know this, thank you. Works like a charm.

Back on topic...

Hi,

Thank you.

What's confusing me, is other 3D BD movies I've ripped, like The Hobbit, I don't see this second video option?

I guess, I ripped them not realising I de-selected the 3D video option.

Yes that's possible, but de-selecting something is a mindful act. Note that MakeMKV does not select MVC by default; you have to do that yourself. So probably that is what you didn't realise.
