Thanks for the quick-look-reply!
Interesting/good to know. Is this an MXF-specification thing or an
(ffmpeg) implementation thing?

Might this be the reason why some institutions store J2K-lossless in MXF
as "field-as-frame" with double framerate?

What do you mean by "field encoding"?

The scenario here is as follows:
Source is uncompressed, interlaced NTSC and shall be stored as
J2K-lossless in MXF.
Therefore the intention of having the resulting MXF containing all the
right metadata to be aware of scan-type and field-order.

Thanks for everything,
