Blu ray file Has Mixed Content

Post by filmteknik »

I run a screening room and a client has booked us for a social gathering to show a movie off Blu-ray which they have licensed via Swank. Just for my own amusement I've decided to make a DCP. I've done this many times for private use.

I ripped the disk via MakeMKV. I checked the results playing on VLC. Biggest file is the complete movie.

But when I "add file" to DCP-O-MATIC and look at it the video shown is one of the "making of" videos. Rechecking the file on VLC I see the movie is video track 1 and the making of is track 2. But DCP-O-MATIC is picking up Track 2. Is there a way to select the other track or must this be done at the ripping stage?

Hi,

Unfortunately there's no way to select between video streams in DCP-o-matic at the moment (though it is on the list of things to add).

With MKVToolNix you can alter MKV files, so you can remove the unwanted video track.

Thanks, Carl.

I think I got it licked. Not a DCP-O-MATIC issue. I the interest of anyone else coming here for help I was able to deal with file in MakeMKV where a checklist appears and I unticked all items except the basic video and main sound and rip just that. Checking in VLC showed just one video track. Looked proper in DCP-O-MATIC. It's running now.

It's usually best in MakeMKV to restrict yourself to extract what you really need for conversion.
Also because DCP-o-matic will analyse all content after importing, and that will take A LOT longer if unnecessary video, audio and subtitle tracks are present. There are of course tools available to strip MKV from unnecessary tracks.
