Thanks, got it now! I use a different rendering process, and at this time, there's no need for this (the GPU can do all the work real time). Everything I've dealt with so far didn't require pre-rendering yet. I may end up doing this in the future for insanely complicated scenarios. Otherwise, I do a lot of optimization behind the scenes for loading the video frames (I've made my own PRORES-lookalike format), while applying all effects on the GPU. If I will end up implementing this, I will also allow for a Refresh footage button :P
