Convert canon's *.VRD to *.DR4 ?
« on: June 14, 2018, 05:38:57 PM »
Hi,
Canon's DPP 4.x (Digital Photo Professional) does not support or read the edits performed onto the raw CR2 files by DPP 3.x.  Since Exiftool can read the *.VRD files from DPP 3.x output, is it possible for Exiftool to convert *.VRD files to *.DR4 files such that the resulting *.DR4 can be read back into DPP 4.x?  This would achieve the equivalent of DPP3 to DPP4 migration in terms of the old CR2 edits.

Some of the problem discussion can be found here - http://community.usa.canon.com/t5/EOS/DPP-4-6-10-0-vs-DPP-3-14-40-0-and-Canon-550D-1000D/td-p/201864

Thanks

It is possible, but unlikely that this would work.  You would have to start with a blank DR4 then try to copy all of the tags from a VRD to see what happens.  I'm sure it wouldn't be complete, but you may be able to copy over some of the edits.

So it sounds lots of work and error-and-trial, especially if one starts from scratch.  Any similar discussion or attempt before?

Yes, it would require some experimenting.  I don't recall anyone trying this before.
