I was wondering if its possible to prerender a composition 100% in-file (NOT prerendering out then bringing back in).
Prerender might not be the best word - I'm essentially looking to do what rasterize does to a smart object in Photoshop. I want to take the output as is and make it so if I change any of the compositions inside the to-be-prerendered comp, the output DOES NOT reflect those changes.
It would take the comp and turn it into non-editable footage.
If anything like this is possible, please tell me how! I can't just pre-render normally and bring it back in due to storage limitations - if what I'm describing doesn't exist I'll have to find another way
