JPEG 2000 MXF OP1a preset needs support for interlaced media
The JPEG 2000 MXF OP1a preset currently supports only Progressive output in the Basic Video Settings but we desperately need support for both interlaced sources and properly interlaced output to meet the JPEG 2000 archival requirements of the Library of Congress and other archival organizations.
We have a growing backlog of interlaced 1080i 59.94 program files that need to be converted to lossless, interlaced JPEG 2000 files for archival delivery, compliant with ISO/IEC 15444-2 specifications. I would point out that such files have become a core deliverable for many broadcasters, distributors and funding and production tax credits agencies, both in the US and in Canada. I would therefore submit that this issue should be given the highest possible priority, especially since all other aspects of this preset appear to be working fine and the only real "show-stopper" is the current lack of support for interlaced input and output, which should be a relatively quick and easy fix since it's fully supported by the JPEG 2000 standard. I have found many other references to this issue on the Adobe boards and other forums so I believe there is widespread support for this effort. Thank you in advance from the entire broadcast industry for making this a priority feature request.

We did not find an actual J2K alternative that could support interlace so we ended-up having to create deinterlaced versions of some of the source masters - not an ideal situation at all, but we really had no choice in order to clear the processing backlog. We did not use Adobe's deinterlacing engine but rather Red Giant's Shooter Frames plug-in with adaptive deinterlace enabled.
I have tried repeatedly to impress upon Adobe the importance of having support for interlaced media in their JPEG 2000 MXF OP1a preset and I was told it would be added in "a future release" without any time frame commitment. I do hope this is correct, but I'm not holding my breath.
Hi David - did you end up finding an alternative? We are in a similar situation, having much interlaced footage requiring archival. The need for interlaced output for the J2KMXFOP1A preset is long overdue! I hope Adobe implements this soon, as there are quite a few people I know who are waiting for this feature to be provided.
