Okay so I’m pretty new at this After Effects thing but I edited a scene for Mustafar from Rogue One. The very beginning of the scene still has a portion from where I removed the ship, but I didn’t know how much to cut (some editors like to play around with footage or maybe it could be taken away with a wipe or something). It’s only a couple of seconds but maybe it could be useful.
That’s quite a good start! I’m glad someone was willing to help out! Keep at it and soon it will be perfect! Hopefully there are more people like you who want to experiment with some things on this list? 😃
