Send to the reder queue only those scenes that need to be rendered, clean up the rest in the render queue
a) check which fonts you used in the project, and copy them manually to a separate folder, naming it Fonts
c) make a collection for the selected compositions.
An AE project can contain dozens of compositions, of which one or two are required to render. In order not to save, and then upload unnecessary gigabytes to the server, you need to understand what compositions you want to "collect" and before this procedure, select them in the Project panel
Once the desired compositions are selected, we proceed directly to the creation of the collection of our project.
