This release introduces significant improvements to multi-clip timeline editing, allowing users to perform more operations across video and audio clips in a single action.

Release highlights

Multi-clip duplication: Duplicate multiple selected clips across tracks while preserving their relative timing and synchronization.

Clip attribute clipboard: Copy and paste audio and picture adjustments without changing the original media or clip timing.

Batch editing: Mute, unmute, or reset picture adjustments across multiple selected clips.

Frame-accurate movement: Move selected clips together in one-frame or ten-frame increments.

Reliability: Improved validation, atomic undoable operations, documentation, and automated regression tests.

It remains free and open source under the GPL-3.0-or-later license. Users can work with their media locally without mandatory cloud processing.
