I have a set of photos and videos that shares a common tag in Shotwell. I'm able to verify those photo files in Nautilus and assert that this tag is written in it. This is confirmed either by exiftools. However, this does not happens in video files. Nautilus doesn't detect any tag, as well as exiftool.
This way, I'm supposing that Shotwell isn't writting this tag to video files. How can I fix this?
