Finally I was able to try this today and it worked but some special
cases would not. For example:
oiiotool in.dpx -sattrib ImageDescription {TOP.dpx:InputDevice} -o out.jpg
I am getting:
oiiotool ERROR: expression : unknown attribute name `dpx' at char 8 of
`TOP.dpx:InputDevice'
am I missing something or is this case just not covered by the current
implementation?
Regards,
Sebastian

YES! That's a great idea. You should be able to copy one image's
metadata to a field of a different name entirely using the expression
evaluation. For example, this would copy the DateTime field into the
image description field:
oiiotool old.jpg -sattrib ImageDescription {TOP.DateTime} -o new.jpg
That's with the current master branch only, because this expression
evaluation is not in the release branch 1.5.
Ok, but it's possible that this is not necessary at all. I think that
the DPX reader should try hard to load the DPX timecode into the
generic "DateTime" metadata field, and also the JPEG writer will put
the generic DateTime into the Exif data. So it may just work with no
help at all:
oiiotool old.dpx -o new.jpg
Does that already do what you want? If not, then I think Justin is on
the right track.

Maybe you can do that with the new expression support that Larry added?

I haven't tried that, but you could possible set a metadata value
from the expression that evaluates from another metadata key?

Hello,
is there a way with the current oiiotool to map/transfer metadata
from one field name to the other? For example: I would like to
put a dpx's timecode into an exif field of a jpg (that is created
in the first step). As far as I can see, currently the metadata
fields can only be set explicitly to key> value.
Best,
Sebastian
