Suspicious video mxf file size #18

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago
What steps will reproduce the problem?
1. Create a 3D DCP (with DcpMaker)

What is the expected output? What do you see instead?
For the same image source, the *.video.mxf size is much more larger than:
- a *.video.mxf generated by a doremi orca wrapper
- a *.video.xmf generated by opencinematools 1.0.1 with one image sequence
at 48fps

It a ~1.8 ratio. 

What version of the product are you using? On what operating system?
1.1.2
windows

i have just made the same finding.  same workflow for a very short test
the doremi cineasset made a stereo dcp with video mxf of 213mb and OCT made a 
video mxf of 424mb.  double the size.  this makes me think it is not coding the 
files for the 125mbit rate for each eye to be compliant but makeing them coded 
as 250mbit each.

i am using the windows gui to do this.  is the gui not putting the correct 
switches in when it runs?
