They already are. My first file starts out with
TAOWB_00000

and ends with

TAOWB_117529

Used OpenDCP to create a DCP and followed the instructions to the letter from the tutorial found on Vimeo. The frames of video and audio matched up perfectly and the DCP seemed to generate fine.

The film (about 80 minutes long) plays fine for the first few minutes, then randomly begins to interlace the video image with random frames from elsewhere in the movie.  I have included a view of what it looks like when played. The closeup image of the little boy should not be there. The audio seems fine. This happens throughout the film.

Number of frames is 117430

Link to the video showing the problem is as follows:

I am using the QuVis 1.0.8 - (165) DCP player to test the DCP's, for which I only had access to for another few days before it expires.

I also checked the JPEG2000 files to see if this is occurring in the source frames and it is not. The frames for this segment and all others I can see are fine and do not contain random frames from elsewhere. This problem seems to be generating when the DCP is created.

I am using OpenDCP 0.30.0 with all standard default settings for the DCP creation. I am using a Mac with OS X 10.10.1.
