High clock-speed CPU (After Effects relies heavily on single-core CPU speeds) 📦 How to Access This Specific Version After Effects System Requirements - Adobe Help Center

: Powered by Adobe Sensei AI. It dramatically speeds up the process of isolating a foreground subject from a background. It handles edge propagation, motion blur, and occlusions much better than the legacy Roto Brush.

Version 17.5 was a highly notable release for After Effects because it brought machine learning and major 3D workspace overhauls.

The v17.5.1 patch is purely a stability and performance bug-fix update. If you are running 17.5.0, installing this patch directly eliminates several prominent workflow-crashing bugs:

: Fixed black artifact frames and garbage pixels tied to QuickTime Avid DNxHR 444 exports containing an alpha channel.

: Fixed broken keyboard shortcuts where holding Alt or Option failed to interact properly with wireframes and 2D layers inside 3D compositions.

is a specific maintenance update released in November 2020. It builds directly upon the major features introduced in October 2020's version 17.5 (internally codenamed "Quarantuna") by resolving critical software bugs.

: Adobe completely revamped how users work with 3D layers.
