Join Alan Demafiles for an in-depth discussion in this video Using prerenders, part of After Effects CC 2018: VFX Essential Training.
- [Instructor] Often we have have built up…a heavy composition, it's helpful to create prerenders…to speed up our work.…Generally, if we have an element…that we are using over and over again as a precomp…or we know that a certain section of our shot is locked…and not going to change,…then we can create what's called a prerender.…The idea here is that by creating…a render of these elements,…we're asking After Effects to calculate less…and speed up our workflow by reading those elements…off of our hard drive instead.…So here in this composition,…I've got some fire that I've introduced…and it's a precomp that I'm using.…
I've got four instances of it here.…And you can see as I'm previewing, it's chugging along.…And of course, there's other elements in the scene…that are contributing to the longer preview time.…However, if I wanted to populate more of the scene…with all this fire, generally I'm looking for redundancies…or anything that I can do to help out my speed here.…So what we can do is prerender this fire…and I'll come over here to my composition…
