Hi all.
Does anyone have any pointers on converting a 3D bluray to DCP? The
bluray which is the source in this case has the 3D encoded as MVC. From
my reading, this means the right eye picture is encoded as a separate
stream (which is a delta from the left eye).
Have ripped the bluray with MakeMKV which recognises that it's an MVC-3D
stream. And the file it outputs appears to be the right size so I think
MakeMKV is not dropping the extra stream or something like that.
But I haven't found any software that can display both eyes at present.
DCP-o-matic doesn't see it, and nor does Bino 3D player or VLC.
I'm on Mac but can get hold of a Windows box if I need to.
Anyone encountered this before?
Many thanks,
Jim
Hi…
…not the first time I do that but today I fail…
DCP-O-Matic 2.10.5 git 61b5d4ad8 on Ubuntu 14.04.
I have a dvd to convert to dcp.
First thing I did was concatenate the 4 vob into one file :
cat VTS_01_1.VOB VTS_01_2.VOB VTS_01_3.VOB VTS_01_4.VOB | ffmpeg -i -
brialy.mp4
Then I use some personal script to get some kind of 5.1 sound → file
becomes brialy_51.mov
Now in DCP-o-Matic conversion always stops @ same number of images (
about 4500 ).
There's some warning in log @ line 2407 FFmpeg: Warning: data is not
aligned! This can lead to a speedloss
Files attached are log, ffprobe.log andmy script for 5.1 upmix.
I suspect more has to be done regarding « concatenate » the vob into one
single.
Any hints / help welcome.
Best regards,
Gerald
Hi all.
I'm trying to make a DCP from a TIFF image sequence.
The post house providing the image sequence say that it's XYZ colour
space. But when I create a DCP from it, it comes out with a green tinge.
I've used colour conversion "none" setting and this is on DCP-o-matic
v2.10.5.
I don't have access to a projector, so am judging the success (or not)
of the conversion using two methods:
1. Viewing in Easy DCP Player demo
2. Converting DCP to ProResHQ Quicktime with ffmeg (ffmpeg -i j2c_...mxf
-c:v prores -profile:v 3 output.mov)
Here's an example still from the sequence:
http://www.cinebox.co/clock.tiff. The clock should be white but instead
has a green tinge.
I can see 4 possibilities:
1. DCP-o-matic is erroneously introducing a green hue
2. I'm using wrong settings in DCP-o-matic
3. My methods for viewing the resulting DCP aren't colour-accurate
4. The image sequence isn't in fact XYZ
Can anyone offer any suggestions?
Many thanks,
Jim

I suggest you take a step-by-step route: Try to create a simple 10s Interop DCP from a still image, no audio, no extras. Format a USB stick to FAT32 using the Macs Disk Utility. After DCP-o-matic finished creating the DCP, select ‚Show DCP‘ unter Jobs - the DCP folder will be highlighted.
Copy only this DCP folder (not DCP-o-matics project folder) to the USB stick, then try to ingest on the GDC.

I have doremi servers that load my content no issue.
I have one GDC sx3000 that I can't get it to load content at all. Any ideas
or suggestions on what I need to do?

It should be ‚Ajouter‘ in your french GUI. You need to select multiple VOBs and use ‚Ajouter‘, or 'Join‘ in the english version.
Another software I regularly used for fixing stream inconsistencies is MPEG-Streamclip.

I'm testing 2.11.10 under Ubuntu 14.04
Most of the time having this error at the very end of hashes and all.
I get all the MXF but no XML.
Error: Programming error at ../src/lib/reelwriter.cc:403
Anyone else?

I tried it and it seems the file is no problem (3d-lg-sports-highlight-(www.demolandia.net).m2ts)
- Create a new project
- add m2TS file
- under Content ->Video, choose ‚3D left/right‘
If you play preview already now, you should see the image stretched properly in the preview area, and while playing, you see a ‚jittering image‘, L and R plays frame consecutive.
Now, under DCP make a checkbox at ‚Video‘ - ‚3D'
The Left Eye/Right Eye selector will then become active below the preview image, and you can switch between left eye only and right eye only for preview. And the jitter goes away. Then hit ‚Make DCP‘.
So, in short words - you need to tell DCP-o-matic which 3D format your source is, and tell DCP-o-matic you actually want to create a 3D DCP.

That appears to be a side-by-side 3D clip - left and right in one image. I assume you made yourself familiar with these types? You have to configure the proper content 3D type so DCO-o-matic knows where to look for the left and right side images in your content.
I’ll try this one and see wether it works for me...

I am not an expert on 2D-3D depth conversion, but from what I know, the material in that specific THX trailer wouldn’t work with automatic/software based conversions, as there are simply not enough distinct shapes/features in it to use for that sort of conversion (aside from the THX logo at the end).
I don’t know if THX ever offered native 3D versions of these trailers.
