Rotoscoping Deletes Work?!?
Hi there,
I’m missing something here when masking out this little scene in my video… need your help!
I have a guy opening the back doors to a truck…. and I want this overlay behind him showing the payload capacity specs for the truck.
But after going through all of the trouble, frame by frame, to meticulously mask the overlay so that it seems behind the guy… when I scroll back to preview my work, the program distorts the mask on each frame, erasing all my work.
So I thought I wasn’t making the keyframes, but the keyframes are there for each frame…. it doesn’t let me NOT make a keyframe.
So why do the masks keep changing?
Ironically, the first half of the clip was changed/erased… but when I scroll back over the latter half of the clip, Premiere has “accepted” these masks and isn’t erasing them. See this photo:
How am I doing it wrong? thank you!

Ok thanks, Dave! I’ll try that.
Kinda reminds me of that old Seinfeld episode about how the car rental company knows how to “take” the reservation, they just don’t know how to “hold” the reservation.
Premiere knows how to let me make the mask, just doesn’t know how to hold the mask in place once I click over to the next frame.

Dave, you sure there isn’t an easier way with Premiere?
I know I said the word “rotoscoping” but it’s just masks that I’m messing with here.
How does a mask set in stone on Keyframe 1…. then distort itself…. after work on Keyframe 25 is completed….?
It doesn’t matter if that mask is a square or a custom line…. it shouldn’t change/erase the work.
If you needed to blur out the McDonald’s logo in your video… you’d create a mask, dial up the blur, and move the box along each frame (I know you can auto) in line with McD logo. What is the difference here? I don’t think you’d take that example into After Effects to do…?

Ok thanks for that confirmation. Sometimes I expect these programs to perform flawlessly and just assume it’s my error somehow (of course, most of the time it is).
I’ve got AE and while I’m not as comfortable with it, I’ve gotta suck it up and get on it it cuz I know it’s a valuable tool.
Thanks again for the help.
