hello, I was working on a small project and I came up with the need to know the total time of a playlist from the XML file. in the example below, Shotcut shows that the total is 33,18/30 seconds (33.6s) but when I do the addition of all producers (except tractors) I get 33.237 seconds. What I’m doing wrong? Thank you in advance for any kind of help.
