I used paint in a video. Have gone thru all frames and everything is fine. However, when I render the project. It's as if everything is zoomed in. Please tell me what I am doing wrong. Did it once and everything was fine. Not sure what I am doing wrong. Thanks for your help.
I have no idea what you are doing that may be different from the times where paint worked for you. Please give details of your workflow or reexamine your workflow to try and figure out what you did differently. Check comp settings and render settings and make sure things match up.
Screenshots of your composition settings, render settings, output module settings, and a full shot of your workspace would help us figure it out.
And, once we get this problem sorted, take some time to go through these resources: Getting started with After Effects Those resources are specifically designed to help you avoid newbie frustration.
Welcome to the family. After Effects is hard. Really hard. Like no other software you've ever used. I've been using AE for 20 years, just now kinda getting the hang of it.
