what is it?
"But when I save it in database"
what gets stored in the 'database'( mysql? )
paste me/us the stored
field value and the
table column type you are storing it in?
a ':' is not the same in all column types
https://dev.mysql.com/doc/refman/5.7/en/time.html
you are not dealing with time you are dealing with text
you are not performing time arithmetic (end time - start time)=elapsed time
you are just trying to store and retrive a text value of 'video run time length'
Is this the problem?
