thanks for the reply. Those are some things I’ve never been introduced to. I’ll see if I can look at some tutorials.
I’ve done some tests to see what this would look like if I manage to mask the kid out, just rotoscoping the whole clip. It would be tedious but it could work partially, if only the clip would be stabilized first. Rotoscoping the kid is no longer the heavy issue.
Here’s one frame where I’ve pulled off a separate mask on the mountain layer just to mask out the kid frame by frame.

Clearly I am losing some detail like the strands of hair on his head but I’m not gonna pursue that issue. I also tried placing an adjustment layer on top of everything, I’ve got thin masks running across the horizon on both sides of the kid, putting some blur effects and stuff like that attempting to blend it together and make it less jagged. I’ll need to rotoscope that a little so it doesn’t go across the kid but I’m fine with that.
I’m gonna take a look at what you’ve recommended. Thanks again for the reply.
