Writing to Hasselblad .fff files

[philbond87]

I am trying to write to .fff files (using Exiftool v.12.26) and it's failing.
The documentation suggests that .fff files can be written to, provided that you ignore minor errors (-m).
I'm doing that but writing is still failing.

I'm on MacOs and am trying:

Code Select Expand

exiftool -overwrite_original -m -creator="some text" <file or directory>

Shouldn't this work?

Thanks,
Phil

Hi Phil,

I tried this at first with an FLIR FFF file and of course it didn't work.  But with a Hasselblad FFF file I get this:

Code Select Expand

> exiftool a.fff -make -model
Make                            : Hasselblad
Camera Model Name               : Hasselblad CFV-39
> exiftool a.fff -creator="some text"
Error: [minor] Phocus may not properly update previews of edited FFF images - a.fff
    0 image files updated
    1 files weren't updated due to errors
> exiftool a.fff -creator="some text" -m
Warning: Phocus may not properly update previews of edited FFF images - a.fff
    1 image files updated
> exiftool a.fff -creator
Creator                         : some text
> exiftool -ver
12.39

Phil,

Thanks for testing.
I am trying to update Hasselblad HD6-100D files. I also get the minor warning (but I'm suppressing it with -m.)
It doesn't appear to be updating the files.

Exact command:

Code Select Expand

exiftool -overwrite_original -creator="this is a test" -m <directory>

(again, I'm using 12.26, incase that's relevant)

It doesn't appear to be updating the files.

Please be more specific.  If you get this message, then the file was updated:

Code Select Expand

    1 image files updated

Sorry I wasn't clear.
I am not at my computer now but I got the same warning you showed, but then also "no files were updated due to errors."

(I also checked the files and confirmed changes weren't made.)

I also checked the files and confirmed changes weren't made.

How did you check?  Using exiftool or some other program.

[philbond87]

I checked with exiftool.

"no files were updated due to errors."

Let us know what the error was and maybe we can help more.

Here are details of the error messages I'm seeing:

Given the command:

Code Select Expand

exiftool -overwrite_original -creator="test creator name" -m <file>

I get the following error:

Warning: Phocus may not properly update previews of edited FFF images
Error: Error reading value for IFD0 entry 29
    0 image files updated
    1 files weren't updated due to errors

I really appreciate the help.

Not being able to read an IFD entry is serious. Could this file be corrupted? Does this happen with all your HD6-100d samples, or just this one?

I have an HD6-100c sample here that doesn't have a problem like this, but I don't have an HD6-100d sample.  If it happens with all your files, could you send me a sample so I can take a closer look?  My email is philharvey66 at gmail.com
