Hi!
Thank you for your repsonses, but it didn’t solve my problems for some reason.
I tried using hold keyframes just as you suggested.
AE still can’t render the frame belonging to the hold keyframe. It renders the one before and after it just fine.
And now that i’m using this method i got another problem: the first frame of the second shot has some remnants of the first shot, like if i was fading out the first shot.
Here is a picture of the timeline of the shot in question:

I’m pretty sure i’m doing something wrong, i just can’t seem to find out what it is.
