MPF information invalidated by PM

[Phil Harvey]

When editing metadata, PhotoMechanic inserts information after the MPF APP2 segment in JPEG images.  This invalidates the MPF image pointers contained in this segment.  A number of current camera models by Panasonic, FujiFilm, Ricoh, Samsung and Sony contain this MPF information.  For the MPF spec, see:

I would be happy if you would fix PM to only add JPEG segments before the MPF APP2 segment.

Thanks.

Phil,

This should be an easy fix, although files already "invalidated" won't be fixed by PM - they would have to use ExifTool for example 

Thanks for the heads-up.

I wish these camera manufacturers would think twice about some of their decisions for writing metadata.  It really is a mess as your note points out (and I can think of plenty of other absurdities).

I hope JPEG-XR is rapidly put into use when it is finally ratified (it's taking forever).
