Is there a tool to migrate Picasa's video collection to Shotwell or any other Linux photo / video administrator?

After many years of using Picasa on Windows, it's time to find an alternative, since Picasa is suspended and not maintained for a long time.
I have a large collection of short home videos. The tags have been added manually by me and contain a lot of valuable information. I need to export these videos WITH LABELS to some other photo / video administrator (Shotwell or similar).
I have searched a lot, but all I find are questions, not answers.
Does anyone have an idea of ​​how to solve this problem?
Thanks in advance!
