For me, copying masks have been a rare event. So taking a little effort to precisely make only the changes I wanted were worth the effort. YMMV.
ok, you are right. When I said copy from 1 to 4 was like an example. I took in consideration the menu options which allow select one by one the desired profile, I'm sorry.
My real problem is not the copy from 1 to 4, my real problem is when modify the mask from profile number 1 and want copy this to all others profiles without modify an y other parameter, only the mask. For example:
I have 4 profiles (day, afternoon, mid afternoon, night)
profile numer 1 "min. object. size = 500"
profile numer 2 "min. object. size = 400"
profile numer 3 "min. object. size = 300"
profile numer 4 "min. object. size = 250"
If the option "sync with profilenumber 1" is checked, after save the changes all the profiles take the value from profile 1 and I don't want this. My checkbox "sync with profilenumber 1" on profile 2, 3 and 4 is unchecked, thats mean, each one of this profiles works independents from profile 1, but the problem is with the mask, becasue all profiles sahring the same image and when I edit the mask, after save the changes the profiles 2, 3, and 4 are not reached by the changes on the mas because "sync with profilenumber 1" is unchecked although the mask should be reached by the changes.
This is the reason why I say that
Blue Iris has not yet solved the problem of copying masks.
I don't know if my explanation was clear, my English is not good.
Best regards
