Immich ignores the modification date of videos and thus sorts videos incorrectly in the timeline

The bug

Hello,

I have had this problem for some time now and have not been able to solve it today despite various attempts.
Videos recorded with a GoPro are sometimes sorted incorrectly into the timeline, even though the modification date has been adjusted. Due to the lack of EXIF, I am not aware of any other way to manipulate this.

It works with this video:

And with this one, it's not:

As I am not aware of any other way to manipulate the timestamp, I set the modification date of the videos to 12:00:00 with +1 second per video. Of course I adjust the date. All videos are in one directory, some are recognized correctly (20.09.2024), the others (18.09.2024) are not. The few images in the directory are not critical and are also sorted correctly.

Please help me to understand the behavior of Immich and how/what/where I need to adjust so that the videos are sorted correctly.

Solution: Modify the EXIF data of the file.
