Performance / Caching
Over the past few months, improvements to performance have been my top priority. In some cases, performance is improved more than 10x compared to OpenShot 2.1. Adding huge images to your timeline is now fully optimized, and won’t slow you down. Editing HD videos (5K, 4K, 2.5K, and 1080p) is vastly improved. A new caching engine was built from the ground up, and supports both memory and disk back-ends, depending on the user’s needs. This can be configured in the Preferences, under “Cache”. Also, opening huge projects (with hundreds of files / clips) has been optimized and is up to 10x faster.
