- Previewing your work is an important…subject inside After Effects.…Depending on how complex your compositions are,…it can take significant time to render just one frame,…but you'd like to watch all those…frames played back to back in real time,…normal playback speed.…Well the first thing you might have noticed…is these little green bars appearing…along your timeline panel.…These indicate frames that After Effects…is already calculated to display to you,…and they're currently stored in RAM.…That way if you go back to that frame,…rather than calculating it all over again,…it will pull that frame out of RAM, much faster.…
To move through the timeline,…I'm going to press Page Down,…and you can see that green bar filled in…as I view these new frames that I…had not previously viewed.…And as I move my current time indicator…through these, it displays very fast…cause it's just pulling those from RAM.…It's not calculating them from scratch.…The number of frames that can be stored in RAM…is based on the amount of memory that you have…
