OpenShot 3.5.1 Video Editor Adds New Optimize Preview Built-In Proxy Workflow
The biggest new feature in the OpenShot 3.5.1 release is Optimize Preview, a built-in proxy editing workflow for creating or linking lower-resolution preview files, which should make it easier to work with large, high-resolution, or demanding video clips.
With the new Optimize Preview feature, OpenShot no longer needs to force every preview, scrub, trim, and dialog to rely on full-resolution source media. According to the devs, this helps playback feel smoother, makes the timeline more responsive, and improves the editing experience on real-world footage.

OpenShot 3.5.1 Added Preview & UI Scaling for Better UI/UX Experience | UbuntuHandbook
OpenShot, the free open-source Qt-based video editor, released new 3.5.1 version few days ago.
The new version introduced preview scaling feature named Optimize Preview and other changes that significantly improved performance for the editing workflow.
Different to other video editors (e.g., Kdenlive and Shotcut), OpenShot down-scale the original video sources by generating (or linking to) another copy of videos in lower resolution (e.g., 720p, 360p).
Then, it uses these lower resolution videos for preview playback, trimming, and editing, resulting a very faster and smoother user experience, while, the export process will use the original videos.
