Hello, how are you friends, I hope you are feeling very well, I have a question about Vmix, we are integrating the system for a radio station and we are doing a lower third.

But I would like the lower third to be dynamic and not static, every time when I change the name of the song that the information is provided by an XML, the lower third appears for about 10 seconds and then disappears, how could I build this? or manage to do it?

At the bottom of vMix there is an overlay tab, click on it, and a window will open...On the section marked Duration, change that to 9000 for the overlay number you are using...1-4, now, in vMix, click on that number you chose for your overlay, and see what happens....it should play the overlay, and let it stay for 10 seconds...that is, from transition on to transition off....I use it for all my lower-thirds for functions, funerals, or panel discussions where I want the lower third to appear and automatically go off....all I do, is play the overlay, and forget about it...it goes off by itself....been using that for years now

You need to script a check for the title changing in the database. Essentially you'd have a script running every few seconds to check if the data changed and if it did you'd turn the overlay on in your script and then go back to watching for the next change.

There are plenty of examples of database monitoring scripts in this thread.
