Python doesn't work properly with exiftool

[Faramy]

Hello.

The script has this line:

Code Select Expand

subprocess.run(f'exiftool.exe -Description="{result}" -overwrite_original "{image}"')
Some sites display Description normally.
And some sites (as I calculated by the number of characters) remove spaces, and show spaces instead of characters (by the number of characters.
That is, instead of

Code Select Expand

Curvy road with a sign in the middle of it.shows

Code Select Expand

                               
If you directly write the Description to the file, then everything is fine.

Is there a solution?

[Faramy]

Maybe there is some way to fix this?

I tried to resave, but to no avail.

Code Select Expand

exiftool.exe -P -overwrite_original "-Description<${Description}" "D:\."
How else can you overwrite the Description so that it is correctly saved?

[Malus]

This code is running fine on my site:

Code Select Expand

import subprocess
result = 'myresult'
image = r'd:\test\file.jpg'
_r = subprocess.run(f'exiftool.exe -Description="{result}" -overwrite_original "{image}"')
_r = subprocess.run(f'exiftool.exe -Description "{image}"', capture_output=True, text=True)
print(_r.stdout)
print(_r.stderr)
What's the value of your string "result".

Last, let me encourage you to try pyExiftool. It's using stay_open and much faster then running "subprocess.run(f'exiftool.exe . . .". several times in a loop.



Thanks for reading, malus

Malus, thanks for the tip about pyExiftool. I will try it.
As for result, everything is recorded normally.
And Description is visible in exif. But here are some sites that do not see the Description, which was written in this way.

And Description is visible in exif. But here are some sites that do not see the Description, which was written in this way.

Description is not an EXIF tag, it is an XMP tag, specifically a Dublin Core XMP-dc tag.  All EXIF data is metadata, but not all metadata is EXIF data.

Otherwise, this is FAQ #3. Exiftool has no control over what tags some website reads. Find a file that reads the data you want correctly and use the command in FAQ #3 to figure out what the actual tag you want to write is.

[Faramy]

Is it possible to simply resave the meta-information in the file? This should fix the bug.

It would be great if there was such a command.

[Faramy]

Now I looked more closely.
The uncorrected file has only "Description"
And in the corrected one, this name is still in the "Image Description"
I'll try the command:

Code Select Expand

exiftool.exe -P -overwrite_original "-Image Description<${Description}" "D:\."Warning: Invalid tag name 'image description'

[Faramy]

Tried

Code Select Expand

-P -overwrite_original "-Description<${Title}" Output:

IPTCDigest is not current. XMP may be out of sync

[Faramy]

If I apply this JS, then the whole file is corrected:

Code Select Expand

        btnSave.onClick = function()
        {
            if ( app.document.selections.length == 1 )
            {
                editTitle = wrapper.editTitleRefs[0];
                new_title = editTitle.text;
                editDescr = wrapper.editDescrRefs[0];
                new_descr = editDescr.text;
                DescrToTitle = wrapper.chkCloneDescrBox[0];
                TitleToDescr = wrapper.chkCloneTitleBox[0];
                if ( DescrToTitle.value == true )
                    new_title = new_desct;
                if ( TitleToDescr.value == true )               
                    new_title = new_descr;
                editKeywords =  wrapper.editKeywordsRefs[0];
                new_subject = editKeywords.text.split(",");
                for (var k  =0 ; k < new_subject.length; k++)
                {
                        new_subject[k] = new_subject[k].trim();
                }
                saveMetadata(app.document.selections[0],
                                    new_title,
                                    new_descr,
                                    new_subject,
                                    { sort:wrapper.chkSortBox[0].value,
                                    append:false } );
                reselectFiles();
            }
            else
            {
                alert("Metadata save only for one file", "Error", errorIcon)
            }           
        }   
But I can only apply to one file.
I have to come up with something to apply to the whole folder.

Code Select Expand

exiftool.exe -P -overwrite_original "-Image Description<${Description}" "D:\."Warning: Invalid tag name 'image description'

See FAQ 2.

First of all, this is the error:

Warning: IPTCDigest is not current. XMP may be out of sync

Most likely, python somehow crookedly writes:

Code Select Expand

subprocess.run(f'exiftool.exe -Description="{result}" -overwrite_original "{image}"')

[Faramy]

In general, I found a way out. What is called - with crutches.
Suddenly someone will need it too. I leave it here:
1. In the same script that sends files to the server, I form a csv file from jpg files:

Code Select Expand

exiftool.exe -T -csv -Filename -Description -Subject ./*.jpg > CSV.csv2. I send this file along with pictures.
3. On the server, the csv file is processed and the Description is now normally visible!

[Phil Harvey]

The -T option has no effect when combined with -csv

[StarGeek]

This should fix the bug.

Failing to see where you have shown there is a bug.

It appears more that you don't know what is the correct tag you want to write. Which is understandable given the complete mess of competing standards that is image metadata.

Obligatory xkcd

[Faramy]

Thanks everyone for the help, but choosing with an intermediate csv works fine.

Now there is another problem:

Code Select Expand

    subprocess.run(f'C:/exiftool.exe -P -overwrite_original -Title="{result}" "{image}"')
    subprocess.run(f'C:/exiftool.exe -P -overwrite_original -Description="{result}" "{image}"')
If the file is .jpg, then it normally writes both in the Title and in the Description.

If the file is .mov - writes only in the Title. And the Description in the file remains empty.

And if I change places - it is written only in Description

Code Select Expand

    subprocess.run(f'C:/exiftool.exe -P -overwrite_original -Description="{result}" "{image}"')
    subprocess.run(f'C:/exiftool.exe -P -overwrite_original -Title="{result}" "{image}"')

The problem, as I understand it, is the inability to create a second temporary file, since it already exists:
Error renaming temporary file

Only I don't understand why it creates a temporary file. Isn't it possible to write directly to a file?
