How to make an insert appear in after effects after a certain period of time?
Let's say every minute of the video?

Answer 1

Through action. We create a nested composition and insert the file after a certain period of time. If this is some kind of watermark, then we just play with a value of 0-100%.

Answer 2

We make a layer with an insert. Stretch it for exactly one minute.
We make 4 keyframes:
1. At the very beginning with 0 transparency.
2. After a couple of seconds with 100% transparency. So we made an appearance.
3. We make the 3rd key with the disappearance of the insert after some more time.
4. We make the 4th key at the very end of the minute insert. We don't change anything there.
5. Write loopOut(); layer.

It is possible with an action, as you were told above, but for me it is longer and more cumbersome + you will not be able to change the position of the insert.
