Right-click a VideoClip -> Process -> Ping-Pong Video: runs ffmpeg in the background (forward + reversed video concat, audio played twice), writes <name>_pingpong.mp4 next to the source and imports it. Supports multi-select, silent clips (video-only retry), progress display and unique output paths. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
