I'm using version 5.0.1 and am having some issues converting from MPEG2 to JPEG2000.

I can get the JP2K to work just fine with the projector in 3D mode but in 2D mode the colour space is all wrong like there's a confliction between the player and the projector.

Anyone else using this who can shed some light on why this is happening?

When preparing the files for 2D you are selecting the "Convert to XYZ" option?

Hi Marcial

Thanks for responding. Yes, I am. Are you using this software also? Have you had any issues converting an MPEG2 to a JP2K?

I downloaded the trial version of this just to mess with, and also add to my arsenal of software that I don't have time to learn to use.

I'd like to just create a brief clip that shows our own gift cards, and also a "Welcome to the Roxy" one that I could play at the beginning of the movie. Obviously, quite a learning curve here. But it'll be fun to try to figure it out.

I was working with a mpeg file that was trying to convert it (2D and 3D) and always had troubles with colors. I did a lot of test and finally I found in common that Im using the Convert to XYZ option and that my source file is 24fps or 23.97fps and use the option Convert 23.97 frames to 24 frames. It works

That was it.

It now works on my two DSS-200's but unfortunately comes up as 'unsupported clip' on the DSP-100.

Any ideas?

Thanks for that Marcial! It must be the only thing I didn't try! [Eek!]

For those not willing to spend a fortune on the CineAsset software, I strongly recommend OpenDCP. It's free and works like a charm.

Is your DSS100/DSP100 on the same system software version as your DSS200s? If not, upgrade the DSS100/DSP100 to at least 4.2.1 (3)...last I heard, there is NO CHARGE for that upgrade.

If your dsp100 don't play the clip it is in 25 frames/sec.

Is it possible to have the files you're working with John supplied not as MPEG2, but as say, a 12-bit TIFF sequence?

Try Steve suggestion of upgrading if you haven't. All our Dolby server are upgraded and the clips run well.

Thanks for the tips guys. I'm working on them. I'll let you know how it works out.

Apologies but I'm puzzled by this; aren't DCPs mostly JPEG2000-based today, and having studied the CineAsset User Manual I couldn't find any reference to converting MPEG2 files to JPEG2000? Aren't these two distinct compression schemas?

Isn't the MXF wrapper going to be either MPEG2-based, in which case there might possibly be compatibility issues with current hardware combinations, or JPEG2000-based in which case there should be no problem?

Also, having read the literature, it is frequently explained that it should not be necessary to perform XYZ colour space conversion on MPEG2 material.

It seems like the most robust workflow for DCP creation currently is to start with a 12-bit TIFF sequence, perform XYZ colour space conversion, then encode to JPEG2000 (audio and encryption aspects aside).

Any comments would be appreciated as they might help others as well.
