[thedanimal] “Can I revert back to the original version?”
Well, unless you deleted the original composition after you pre-rendered (there would be no reason to do that) you should be fine. Just find where your pre-rendered footage appears in other compositions and replace each instance with the original comp:
1) Right click the pre-rendered footage in your project pane and go to the bottom option “Reveal In Composition.”
2) Select one of the compositions it appears in from the drop down menu, you should be taken to that composition and the pre-rendered layer should be automatically selected.
3) Drag your original composition onto your timeline while holding option (or alt on PC) to replace the pre-rendered footage with the original composition.
4) Start at step 1 and repeat for every instance of the pre-rendered footage.
