Today we are excited to announce the availability of Speculative Preview in After Effects beta, available in builds 18.4x37 or newer. Download the latest build from Creative Cloud Desktop.
What is Speculative Preview? While AE is idle (e.g., you’ve stopped to admire your beautiful design, checking email, or getting coffee, etc.), the composition that has focus (and any pre-comps in that comp) will begin automatically rendering in the background. You’ll see green cache marks appearing as frames are rendered and you will not lose your place in the preview window. This should allow you to then scrub around the composition with frames already rendered, speeding up your design/preview iteration loop.
You can see Speculative Preview in action in the attached video.
Please use this forum post to discuss and provide feedback.
Thanks!
