How to write image's post date to file's metadata?

[ghost]

I'm trying to download artworks from Pixiv and DeviantArt, with the picture's date applied to the file's metadata. The goal being the file's modified or creation date metadata is set to when the artwork was published. I did this successfully with --write-metadata --mtime-from-date but now I can't get it t work, the file's metadata dates are set to today's date.

I'd also like a .json file containing all metadata alongside the image. I'm trying to do all this using the config file only, without adding any flags in the terminal.

If you could help I would appreciate it. Thanks :)

So you want to use --write-metadata --mtime-from-date in a config file, did I get that right?

In that case, add

    "postprocessors": ["mtime", "metadata"]

to the "pixiv" and "deviantart"` blocks of your config.
